[00:07:19] *** dingo001 has left ##java
[00:07:35] <Olathe> I'll probably just take a String and use a HashMap<String, Class>

[00:44:17] <znoG> a program that fixes all problems in a computer?
[00:44:23] <snooplsm> znoG, no
[00:44:40] <znoG> is it one of those "don't worry, be happy" programs?
[00:44:43] <tiglionabbit> sounds impossible, or like Norton Systemworks for Windows.  Which is quite imperfect
[00:44:50] <snooplsm> no no...
[00:45:13] <cybereal> I don't think he said it fixes anything
[00:45:22] <snooplsm> i don't want to tell you what it is exactly, but i'm sure you wished there was an easy way to do somethign before, and this is that easy easy way.

[00:46:30] * ernimril raises a hand
[00:46:34] <snooplsm> ernimril, its for any problem of your computer.
[00:46:35] <bpalmer> ernimril: that's tautological. Only stupid people use computers
[00:46:39] <tiglionabbit> ernimril: I'm not stupid, but I had a lot of problems with windows

[00:47:27] <snooplsm> let me rephrase that..
[00:47:33] <Garibaldi> yeah, windows woudln't let me resize the bloody console window
[00:47:39] <Garibaldi> :-P
[00:47:42] <znoG> snooplsm: so is it a program to keep track of the problems you've had? is it a program you type a question into and brings up answers based on a smart search system? may as well tell us in general what its about so we can either go "woaaah" or "haha"
[00:47:43] <tiglionabbit> bpalmer: you must be using a computer right now, in order to say that.  Do you include yourself in the set of "retards"?

[00:48:40] <snooplsm> znoG, yes there is.
[00:48:45] <tiglionabbit> bpalmer: because you're typing that message.  What else could you be using
[00:48:47] <Clackwell> Garibaldi: see system menu of the console window
[00:49:02] <Garibaldi> Clackwell: yeah, I want to click and drag and it do the right (tm) thing.
[00:49:07] <bpalmer> tiglionabbit: you couldn't possibly be aware of whether I'm typing a message or not as we speak
[00:49:12] <Garibaldi> I don't want to go to some menu and fiddle with some static setting
[00:49:23] <Clackwell> Garibaldi: that's not the same as "windows won't let me resize the console" though.
[00:49:28] <znoG> snooplsm: it's some remote PC management tool isn't it
[00:49:31] <tiglionabbit> bpalmer: why is that?  I see the results of it
[00:49:48] <snooplsm> znoG, no.

[00:50:07] <bpalmer> tiglionabbit: perhaps your imagination is limited. You're unfamiliar with the concept of voice recognition?
[00:50:14] <bpalmer> of tablets and handwriting recognition?
[00:50:22] <tiglionabbit> bpalmer: those are also computers
[00:50:24] <Garibaldi> Clackwell: I would have thought people would understand the point I was making, my mistake.
[00:50:33] <znoG> snooplsm: btw, if you don't tell anyone at least what it's about, you are risking writing something nobody uses as you didn't allow for criticism before starting.

[00:52:33] <tiglionabbit> bpalmer: I think you will find that an abacus is also designed for computing
[00:52:42] <Clackwell> if the lack of direct resizing support of the console in windows is your biggest complaint about windows, i'd say it must be a kick ass OS.

[01:44:15] <Amnesiac> Because...
[01:45:16] <forsaken> "please implement the class x which inherits from the classes x y and z, obviously she meant interfaces, but in the problem before (which this one references) she made us write them as abstract classes, and this was on a test

[01:57:29] <cybereal> pr3d4t0r: funny, I've always thought we had terminal emulators like WYSE to blame for that, since that's the quadrant they use
[01:57:47] <pr3d4t0r> I believe the most successful "graphics" computer until the Apple ][ came up was the Commodore PET CBM.
[01:58:19] <cybereal> I think it makes sense to do 4th, considering how most framebuffers work
[01:58:21] <pr3d4t0r> cybereal: Tektronics graphics (vector) workstations (like the ones they used for rendering Tron) had 1st quadrant graphics too :)
[01:58:32] <pr3d4t0r> cybereal: It's unnatural, but that's the reason.
[01:58:47] <pr3d4t0r> cybereal: Woz and company figured it'd be cheaper to refresh down than up.
[01:59:28] <pr3d4t0r> cybereal: Then Apple ][ became so insanely successful that TRS-80 and others began implementing graphics that way.
[01:59:40] <The_Vulture> pr3d4t0r: how'd they figure that? (if you know)
[01:59:47] <Stork> how can i get a list of all the files in a folder in my .jar file?
[01:59:55] <cybereal> pr3d4t0r: first time I did graphics was in dos straight to the vga framebuffer, so the calculations were more natural that way imho

[02:00:08] <pr3d4t0r> cybereal: Yup.
[02:00:42] <pr3d4t0r> cybereal: That's because the frame boffer on a CGA/VGA adapter started at b800:0000 and as memory increased, you hit pixles going right and down.
[02:00:58] <The_Vulture> Stork: perhaps using that JarFile class - what do you want to do that for though?
[02:01:12] <pr3d4t0r> The_Vulture: Because of what I told cybereal; older systems had the video memory mapped (and handled) in the main bus.
[02:01:21] <Stork> not sure really :p
[02:01:27] <DemisM> why doesn't this line work when running the app? String[] testString = myString.split("+");
[02:01:31] <Stork> seemed like a good idea at the time
[02:01:47] <pr3d4t0r> The_Vulture: So what cybereal said makes sense (and it made sense to Woz):  Pixel 0 is offset 0, pixel 1 is offset 1 and so on (oversimplified but you get the idea).
[02:01:48] <The_Vulture> pr3d4t0r: still not sure why that'd make it cheaper to scan one way than the other..
[02:01:48] <MacIver> DemisM: why are you doing that?
[02:01:56] <The_Vulture> DemisM: RTFM for that split method you're calling
[02:02:19] <pr3d4t0r> The_Vulture: The corollary is that CRTs scan also (from your POV) left-right, top-bottom.

[02:04:36] <pr3d4t0r> MacIver: We had a kid a few weeks ago trying to parse all kinds of weird shit with regexp in Java.  A good 20 lines of Java code, pain in the arse to debug, etc.
[02:04:39] <DemisM> I guess I don't know what legal regex's are
[02:04:58] <cybereal> DemisM: it varies by implementation
[02:05:08] <DemisM> ok I would like to split up my String wherever I have a +
[02:05:12] <DemisM> how would I do this?
[02:05:13] <pr3d4t0r> MacIver: Since the processing wasn't critical to his program, I handed him an awk script, one short line, that did the same thing.  He'd instead call that prior to running his Java program and tutti contenti.
[02:05:17] <cybereal> there is an RFC for regex's and all it does it point to about 50 different OTHER rfc's for regex implementations

[02:12:42] <pr3d4t0r> DemisM: Yeah.
[02:13:06] <pr3d4t0r> DemisM: Your polynomial terms are separated by = or - signs.
[02:13:23] <DemisM> right

[02:13:55] <pr3d4t0r> DemisM: I'd use an ArrayList, a for statement, and the charAt(nPos); method for String.
[02:13:59] <pr3d4t0r> DemisM: Yup.

[02:15:08] <DemisM> sure
[02:15:55] <The_Vulture> DemisM: you're told that the input will be in cannonical form already..
[02:16:12] <DemisM> The_Vulture: so no check is needed?
[02:16:38] <The_Vulture> Well you could write some really robust code with checking & all, but it doesn't seem to be required.
[02:17:35] <DemisM> in my spec. I would say in the precondition: a polynomial in canonical form is provided. This would make the user of the class responsible no?
[02:17:45] <DemisM> not me
[02:18:04] <The_Vulture> sure
[02:18:16] <DemisM> k :)
[02:18:34] <The_Vulture> well the only thing stopping you from keeping the whole thing in one String is that the spec requires "discrete objects" - if the class actually provided useful operations on Polynomials it might actually be in interesting task

[02:25:32] <pr3d4t0r> DemisM: Because unlike what most Java pundits will try to make you believe, Java is a big kludge.
[02:25:38] <The_Vulture> DemisM: well "length" on a vector could be somewhat misleading - confusing the ideas of a mathematical vector's length. As for why not use size on a string.. *shrugs*
[02:25:40] <Honk^away> DemisM: texts dont have a size :p and containers dont have a length =)
[02:26:05] <pr3d4t0r> DemisM: Languages such as Smalltalk, Ruby, Objective-C, etc. picked one and stuck to it :)
[02:26:16] <The_Vulture> well that's also true - many containers aren't sequences, so the term "length" would be a misnomer - they are really just bags of things, so size makes more sense.
[02:26:26] <The_Vulture> size is the more generally usable term
[02:26:46] <pr3d4t0r> The_Vulture: If you take the high road, it doesn't matter.  You can make the case for either.  Consistency would've been preferred.
[02:26:48] <The_Vulture> Interestingly enough C++'s std::string has both (size() and length(), they are synonymous).. (and it's containers have just size())
[02:27:10] <pr3d4t0r> The_Vulture: In Smalltalk, size is the way to go because strings are collections of characters.
[02:27:11] <grifis> why when doing in.read(buf,0,7) for recv only numbers...i received also next string sent by client ? for example '10rt' ... (rt is the second request)
[02:27:16] <The_Vulture> pr3d4t0r: I think it'd be harder to make a case for length() as a general property of all containers (sets, bags, lists, maps, etc)
[02:27:21] <The_Vulture> but yes, consistency is the real key
[02:27:34] <pr3d4t0r> The_Vulture: Yeah.  I'd hate to see length -- size is more like it.
[02:27:49] <The_Vulture> pr3d4t0r: Yeah - that's true in C++ too, why length() got in there at all I'm not sure. Probably some poor attempt to make it consistent with other existing string types.
[02:28:17] <The_Vulture> I should go back and check the minutes from some of the standards committee meetings one day, just for a laugh.
[02:28:31] <The_Vulture> all of these trivial details were presumably given far too much thought

[02:30:49] <pr3d4t0r> DemisM: There were things like Colour() instead of Color(), and other typos.  It was funny as hell reading the Java 1.1.0 spec.
[02:31:23] <pr3d4t0r> DemisM: The problem was that some brits had worked on it so it wasn't consistent; either that or some class/method names had typos in them.

The problem is that the while loop taken 1 second to complete, so setting a varible false will not work right away. How do I stop the thread instantly?
[02:43:21] <pr3d4t0r> cybereal: The scanner will read all the characters but if it runs into white spaces, it'll ignore them and just pass the meaningful symbols to the parser.
[02:43:46] <cybereal> pr3d4t0r: but without the spaces it won't know the difference between 'new Object()' and 'newObject()'
[02:44:06] <pr3d4t0r> cybereal: Everything in a language definition is a symbol; you have language symbols and terminal symbols.  Language symbols are those that can be defined in terms of other symbols.
[02:44:27] * pr3d4t0r wants to smack cybereal
[02:44:43] <pr3d4t0r> cybereal: Terminal symbols are those that can't be reduced to anything else.
[02:45:01] <pr3d4t0r> cybereal: Anyway, your example with newObject() is validating 100% what I'm telling you.
[02:45:10] <cybereal> pr3d4t0r: it's also validating that space isn't ignored
[02:45:13] <pr3d4t0r> cybereal: In Java, that'd look like a method name.
[02:45:30] <pr3d4t0r> cybereal: Dude, IT IS BEING IGNORED BY THE PARSER.
[02:45:56] <pr3d4t0r> cybereal: new           Object(); and new Object(); are THE SAME because the spaces are ignored by the parser.
[02:46:08] <pr3d4t0r> cybereal: Your example is dicking with the SCANNER, not the PARSER.,

[02:49:38] <javabot> Mc_Fly, please see java.lang.Thread: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Thread.html
[02:49:43] <Honk^away> wohow :)
[02:49:55] <pr3d4t0r> cybereal: Because I'm Mexican.  It doesn't sound right otherwise ;)
[02:50:15] <cybereal> pr3d4t0r: heh, look up the word ethereal; it's based on that pronunciation
[02:50:30] <pr3d4t0r> cybereal: Will do.
[02:51:05] <pr3d4t0r> cybereal: So anyway, in the second case, if the scanner passes SYMBOL_NAME(newObject()) to the parser, the parser will look it up in its symbol table and throw an error if it isn't defined.
[02:51:18] *** frivol has joined ##java
[02:51:56] <pr3d4t0r> cheeser: :)
[02:53:28] <cybereal> pr3d4t0r: if you used a parser generator would you have to scan out spaces before using the generated parser?
[02:54:02] <pr3d4t0r> cybereal: Depends on what your syntax definition defines as a white space.
[02:54:13] <pr3d4t0r> cybereal: "White space" is an arbitrary definition.
[02:54:55] <pr3d4t0r> cybereal: For example, in the bash parser one of the definitions of white space is something like:  SHARP ALPHANUM EOL
[02:54:57] <cybereal> pr3d4t0r: also on the comment about 2 'r's in my nick; lots of english speakers do that too, I was just noticing the trend the other day
[02:55:08] <pr3d4t0r> cybereal: He, he, he...
[02:55:18] <pr3d4t0r> cybereal: I've been accused of speaking English too.
[02:55:33] *** Stork has quit IRC
[02:55:33] <cybereal> pr3d4t0r: sorry, I mean native english speakers :P
[02:55:43] <pr3d4t0r> cybereal: Or rather, SHARP STRING EOL
[02:56:03] <pr3d4t0r> cybereal: SHARP STRING EOL --> # This is a bash comment
[02:56:33] <cybereal> pr3d4t0r: I guess my point is lost on all of this; the whitespace isn't always ignored in C like languages at some point, maybe the parser ignores it because it never gets it but whatever, it's semantics.  You can't write all of java constructs without any whitespace.
[02:56:39] <pr3d4t0r> cybereal: STRING ::= CHAR STRING | CHAR
[02:57:02] <pr3d4t0r> cybereal: Dude, stop being stubborn and go read about compiler design.
[02:57:51] <cybereal> I don't think I'm the one that is being stubborn :)
[02:57:58] <pr3d4t0r> cybereal: It's not "semantics".  There is 60 years of research defining all this stuff precisely.  What you need to do is learn that terminology instead of arguing about whether your definition of white space matches what Aho, Kernighan, and co. said.
[02:59:26] *** sched has quit IRC
[02:59:28] <pr3d4t0r> cybereal: So yes, you're being stubborn because there is very precise terminology about what a parser, a grammar, a scanner, white space, etc. are or how to define them, and you're either chosing to ignore it or really not know it, yet you insist on creating an inaccurate interpretation of what they mean.
[03:00:31] <cybereal> pr3d4t0r: i'm not saying you're wrong, I'm just saying you missed my point
[03:00:39] <pr3d4t0r> cybereal: OKi.
[03:00:41] <cybereal> pr3d4t0r: WHen you boil it all apart then definitely, there is lots more to it
[03:00:55] <pr3d4t0r> cybereal: I like boiling it to that part ;)
[03:01:09] <Honk^away> pr3d4t0r: not talking about compilers though, he's right :P
[03:01:16] <Honk^away> whitespaces in java are not always ignored :)
[03:01:26] <pr3d4t0r> cybereal: For example, in C/Java/C++, "The spaces here               are meaningful" but not to the LANGUAGE.  They're meaningful to the string definition.
[03:01:38] <cybereal> pr3d4t0r: yeah, I get that
[03:01:51] <Honk^away> maybe you should just stop now you've found a consense :p
[03:02:02] * cybereal concurs
[03:02:15] <pr3d4t0r> Honk^away: I'm just bitchy because I only slept three hours since Saturday at 0600.
[03:03:09] <Honk^away> yeah, but seeing 2 ppl argue when they actually say the same thing is confusing =)
[03:03:29] <pr3d4t0r> Honk^away: I'm not saying the same thing.  Never did.
[03:03:45] <Honk^away> cybereal's saying the same thing as you though
[03:03:46] <Honk^away> now :)
[03:03:55] <cybereal> Honk^away: we were talking about different things, without really specifying properly
[03:04:06] <Honk^away> cybereal: "you were"
[03:04:10] <cybereal> well whatever

[03:06:23] *** wonea has joined ##java
[03:06:23] <cybereal> BSD zealots are the only people worse than debian zealots
[03:06:25] <Mc_Fly> I have a thred that looks an a varible every now and then. And a userinput that sets this varible. Do I need synchronized keyword around the varible? I'm a bit confused as I only have 1 thread and the docs states that synchronized is needed when more threads access the same code at once
[03:06:27] * Amnesiac sets The_Vulture on fire
[03:06:32] <pr3d4t0r> The_Vulture: Ah, so shit sandwich then.
[03:06:37] <Amnesiac> pr3d4t0r, decent GUI == twm
[03:06:38] <Amnesiac> :P
[03:07:01] <pr3d4t0r> Mc_Fly: What type is the variable?
[03:07:10] <The_Vulture> pr3d4t0r: Working well at the moment, but who knows what tomorrow might bring.. (actually I've not had any severe failures in Sid in the 3 years or so I've been using it)
[03:07:24] <Mc_Fly> pr3d4t0r: double[]
[03:07:29] <pr3d4t0r> Mc_Fly: If it's a primitive other than long or float, you don't need to worry about synchronization because updates to such variables are atomic.
[03:07:33] <cybereal> hm I'd post the last 20 lines to bash.org but I doubt most people there would get the humor
[03:07:43] <pr3d4t0r> Mc_Fly: OKi, you  need to synchronize then.
[03:07:52] <The_Vulture> Mc_Fly: and by "access" you mean read/write values in the double[], or change the value of the double[] itself (ie: make it refer to a different array)
[03:08:13] *** wonea has left ##java
[03:08:19] <pr3d4t0r> The_Vulture: Ah!  Good question.  I assumed RW.
[03:08:32] * pr3d4t0r smacks himself in the head for assuming things.
[03:08:51] <Amnesiac> Having a Collection.iterator() is there any safer way to modify the Collection while iterating over it? say another thread is adding elements to the Collection and another thread was iterating by using java.util.Iterator;
[03:08:59] * Amnesiac assumes pr3d4t0r is chilango
[03:08:59] <The_Vulture> pr3d4t0r: Yeah, I assumed read/write, I just wasn't sure if he was modifying the array reference, or the array members, or both. If he's only accessing the members he can lock on the array object, if he's modifying the reference he'll need to lock on something else
[03:09:09] <The_Vulture> pr3d4t0r: depends on the kind of updates he wants to do.. (hmm.. is an increment atomic? what about += ?)
[03:09:12] <Mc_Fly> pr3d4t0r: Thanks
[03:09:15] <The_Vulture> that was out of order..
[03:09:26] <pr3d4t0r> The_Vulture: I'd assume the array elements; modifying the reference is also atomic :)
[03:09:53] <pr3d4t0r> The_Vulture: It'd be crazy, but it is atomic and doesn't need to be synchronized :)
[03:09:56] <Mc_Fly> The_Vulture: I'm actually changing the object, as I'm initializing a new array.
[03:10:04] * pr3d4t0r madrea a Amnesiac
[03:10:09] <Amnesiac> heh
[03:10:21] <Amnesiac> Yeah I know, being called a "chilango" is worse than a "mentada de madre"
[03:10:24] <Honk^away> Mc_Fly: then synchronize on something :p
[03:10:27] <pr3d4t0r> Amnesiac: Indeed.
[03:10:34] <The_Vulture> pr3d4t0r: *nods*
[03:10:38] <pr3d4t0r> Amnesiac: I'm poblano, raised celayense.
[03:10:41] <Mc_Fly> Honk^away: ?
[03:10:47] <The_Vulture> Mc_Fly: and what are you doing in different threads?
[03:11:22] <Amnesiac> Having a Collection.iterator() is there any safer way to modify the Collection while iterating over it? say another thread is adding elements to the Collection and another thread was iterating by using java.util.Iterator;
[03:11:36] <pr3d4t0r> Amnesiac: And you know what they say:  Perro, perico y poblano - no lo cojas con la mano.  Cógelo con un palito porque es animal maldio.
[03:11:43] <The_Vulture> Amnesiac: lock on the container itself, or something else, keep the lock over the entire iteration
[03:11:45] <Amnesiac> maldito* hahaha yeah
[03:11:49] <The_Vulture> the docs explain this clearly
[03:11:55] <Mc_Fly> The_Vulture: I have 1 thread and it reads from the double[]. The double[] is being reinitialiced by interaction
[03:11:57] <Honk^away> Mc_Fly: maybe you should rad some tutorial on threading before actually using it =)
[03:12:03] <Amnesiac> The_Vulture, I DO, but I still get ConcurrentModificationException
[03:12:07] <Amnesiac> and I know the docs say about that
[03:12:15] <Amnesiac> I'm synchronizing on the Collection itself
[03:12:19] * pr3d4t0r checks the docs
[03:12:25] <The_Vulture> Amnesiac: but do you actually lock in other places too.. and/or use a concurrent wrapper..
[03:12:27] <pr3d4t0r> Amnesiac: Dude, the documentation says that you suck!
[03:12:34] <Mc_Fly> Honk^away: I did, but they all regard isues of more that one thread
[03:12:37] <The_Vulture> pr3d4t0r: hehe :)
[03:12:43] <Amnesiac> pr3d4t0r, I'm following that, I'm locking on the Collection
[03:12:44] <Honk^away> Mc_Fly: you have more than one thread
[03:12:46] <Honk^away> obviously
[03:12:49] <MacIver> you are lucky you get that exception...in my day, we had to have erratic behavior if we did crap like that...and like it!
[03:12:57] <Honk^away> one that's reading and one that's writing on user input
[03:12:58] <Honk^away> that's 2
[03:12:58] <The_Vulture> Amnesiac: have you done this: List list = Collections.synchronizedList(new ArrayList(...));
[03:13:07] <Amnesiac> The_Vulture, yes
[03:13:10] *** octoberdan has joined ##java
[03:13:11] <The_Vulture>  Amnesiac then locked on the whole list for the length of the iteration?
[03:13:26] <Mc_Fly> The_Vulture: Ok, so the UI has own thread?
[03:13:30] <The_Vulture> synchronize (list) { for (Iterator<String> i = list.iterator(); i.hasNext(); ) { .. } }
[03:13:31] <Amnesiac> yeah, I place the Iteration inside a synchronized block on the collection
[03:13:35] <octoberdan> Has  anyone here used Tomcat's Realm?
[03:13:39] <Amnesiac> yeah The_Vulture that thing :)
[03:13:47] <pr3d4t0r> frivol: I was successful last night.
[03:13:50] <Mc_Fly> The_Vulture: me?
[03:13:57] <MacIver> Amnesiac: and you do that where you modify it?
[03:14:07] <MacIver> if you only lock in one place it won't help ;-)
[03:14:13] <Amnesiac> I do that when I add to it and when I'm iterating over to it
[03:14:18] <The_Vulture> Mc_Fly: Listeners and the like will be triggered in the event handling thread.
[03:14:33] <The_Vulture> Amnesiac: when adding you don't need to - you've already wrapped it to make it thread safe.
[03:14:34] <Mc_Fly> The_Vulture: ahh ok
[03:14:48] <The_Vulture> Amnesiac: are you sure you aren't doing concurrent operations within your iteration in one thread?
[03:14:53] <Amnesiac> The_Vulture, well I did that because I was checking if that was causing the exception
[03:14:55] <The_Vulture> Amnesiac: pastebin the relevant code and the stack trace
[03:15:17] <Amnesiac> The_Vulture, well while iterating I'm removing using iterator.remove()
[03:15:27] <The_Vulture> MacIver: it will, because the synchronizedList is already providing synch for single operations

[03:15:48] <MacIver> The_Vulture: yeah i realized that when you said it ;)

[03:40:27] <The_Vulture> that doesn't make a lot of sense..
[03:40:50] <The_Vulture> a Pair contains two coordinates, you can't make a Pair that just "doesn't have" one part or another
[03:40:52] <DemisM> 0 is my coord index
[03:41:42] <DemisM> so how do I correctly add a pair?
[03:42:09] <mohadib> cooed.add(new Pair(1,0));
[03:42:28] <The_Vulture> coord.add(new Pair(1, 0), 0) I assume is what you want.. if you want to add Pairs at the begining of your List

[03:59:30] <cheeser> the aolbonics ir probably overkill but yeah.
[03:59:40] <rake> http://pastebin.com/403619 <-- in that code, for some reason I get an error about return types not lining up: I think it has to do something with the catch statement at the very end. Can someone have a look at that and give me a pointer?
[03:59:49] <mohadib> pr3d4t0r: most aolbonics users dont kknow how to read a topic
[03:59:56] <tiglionabbit> like, how do I properly throw a runtime exception?
[04:00:02] <tiglionabbit> preferably with a string

[04:00:19] <mohadib> throw new Exception("BAD!!");
[04:00:19] <cheeser> javabot: tel tiglionabbit about exceptions
[04:00:19] <javabot> Did you mean tell tiglionabbit about exceptions?
[04:00:27] <pr3d4t0r> mohadib: Yeah, but now they can't complain that they haven't been warned.
[04:00:29] <cheeser> bah!

[04:01:25] <pr3d4t0r> cheeser: IMTheNachoMan was nagging earlier that "it's not in the /topic" so I fixed that.

[04:03:01] <The_Vulture> Twiun: thanks

[04:04:09] <Kal-L> in other words, the pic is in the jar file with the rest of the needed files but it still doesn't display
[04:04:14] <rake> The_Vulture, I simplified the code: http://pastebin.com/403622 , and eclipse won't compile it at all, because it says return type has to be the same
[04:04:30] <cheeser> Kal-L: because you don't load files from jars with File
[04:04:40] <cheeser> javabot: tell rake about newbie ide
[04:04:40] <javabot> rake, newbies shouldn't use IDEs.  read:  http://qa.jtiger.org/GetQAndA.action?qids=52&showAnswers=true
[04:04:53] <The_Vulture> rake: you could make it even simpler and still fail.. you said your function returns something, but there are paths through that function that don't have a return statement
[04:05:05] <Kal-L> the .gif pics load fine
[04:05:07] <The_Vulture> rake: and stop paraphrasing the compiler - copy/paste the actual compiler error next time
[04:05:11] <The_Vulture> thanks cheeser

[04:06:24] <The_Vulture> rake: right.. now what value of type MDT is returned when an Exception is thrown (and caught)?
[04:06:55] <Kal-L> got it..
[04:06:57] <The_Vulture> control flow leaps from the point of failure, to the exception handler, then out to the end of the function, never hitting a return statement to return an MDT type..
[04:07:20] <rake> The_Vulture, so I need to define a exception type for a MDT object, basically?
[04:07:27] <The_Vulture> no..
[04:07:37] *** Geren has joined ##java
[04:07:38] <Geren> hi
[04:07:39] <mohadib> heh
[04:07:40] <The_Vulture> you need to make sure that every path through your function returns the type you declared it should
[04:07:41] <Geren> a question
[04:07:46] <The_Vulture> Geren: an answer.
[04:07:56] <Geren> with a Hashtable, can i have two entries with the same key?
[04:08:00] <Geren> like (a,1) (b,1)
[04:08:03] <mohadib> no
[04:08:07] <Geren> its not allowed???
[04:08:11] <mohadib> no
[04:08:22] <The_Vulture> Geren: they'll just overwrite one another..
[04:08:30] <mohadib> how would it know what to give you when you   ht.get("a");
[04:08:33] <The_Vulture> perhaps you want a Map< ..., List<...> > instead..
[04:08:38] <Geren> The_Vulture, well i'm trying to remove duplicates from an array
[04:09:03] <Geren> and the way i do it is that i run through the array, and if the array's value already has a key in the Hashtable, i add 1 to the key
[04:09:15] <Geren> if not, i create a key (1) for that value
[04:09:25] <Geren> at the end, i run through my hashtable and pick out only those values iwth key 1
[04:09:49] <The_Vulture> Geren: so what's the problem?..
[04:10:03] <Geren> but you said i can't have values with the same key
[04:10:06] <Geren> so if two values both appeared 2 times, what do i do?
[04:10:06] <mohadib> yep
[04:10:16] <Geren> i mean that means the Hashtable method does not work?
[04:10:46] <rake> The_Vulture, I'm pretty sure it does: I mean, the whole method goes and fills up the MTD object with variables, then returns it to main
[04:11:55] *** zackk has quit IRC
[04:12:22] <rake> The only reason the try/catch is there is because the user needs to enter some values before they go into the MTD object.
[04:12:36] <Geren> The_Vulture, i mean can do MyHashTable.put(value1, 1) and then do MyHashtable.put(value2.key)
[04:12:40] <Geren> i mean*
[04:12:47] <Geren> MyHashtable.put(value2.1)
[04:12:49] <mohadib> map.put( key new Integer(Integer.intValue(((Integer)map.get(key)))++);
[04:12:50] <mohadib> ;)
[04:12:58] <Geren> huh?
[04:13:02] <mohadib> heh
[04:13:13] <Geren> if i can't have the same key, what am i supposed to do?
[04:13:24] <mohadib> you dont need the same key
[04:13:27] <mohadib> why would you
[04:13:41] <mohadib> you are just takinging an existing key and ++ it's value
[04:13:52] <Geren> mohadib, i use the key to determine how many times a number as appeared
[04:14:01] <mohadib> why the key
[04:14:06] <Geren> then what
[04:14:07] <mohadib> the key should be the item
[04:14:14] <mohadib> value should be how many times
[04:14:15] <Geren> ok hold on
[04:14:25] <Geren> when i do myHashTable.put(a,b)
[04:14:27] <Geren> which one is the key,
[04:14:29] <Geren> a or b?
[04:14:33] <mohadib> b
[04:14:34] <mohadib> er
[04:14:38] <mohadib> a ist the key
[04:14:40] <mohadib> b is the value
[04:14:41] <Geren> a is the key?
[04:14:42] <Geren> ok
[04:14:52] <Geren> so value could be the same, but key must be unique
[04:14:53] <Geren> right?
[04:15:00] <mohadib> yep
[04:16:24] <Geren> mohadib, so using hashtables to remove duplicate values is good?
[04:16:38] *** dingo001 has left ##java
[04:16:56] <mohadib> Geren: there are collexctions thwt will not allow duplicates
[04:17:31] <The_Vulture> mohadib: it's not quite that
[04:17:42] <The_Vulture> he wants to remove all instances of a value that appears more than once
[04:17:51] <The_Vulture> so {1, 2, 3, 2} becomes {1, 3}
[04:18:00] *** Dena|Lap has quit IRC
[04:18:11] <The_Vulture> yes, a Map would be one simple way to do it, though it still sounds like you're not understanding how to use it effectively for this task
[04:18:35] *** Onur_ has joined ##java
[04:18:37] <Geren> mohadib, what are collections?
[04:18:39] <Geren> The_Vulture, yes
[04:20:10] <mohadib> then i would use contains() when making the list
[04:20:29] <The_Vulture> mohadib: doesn't do what's necessary
[04:20:45] <mohadib> i guess im not understanding his problem
[04:20:52] <The_Vulture> you need to keep track of which elements you seen more than once, so you don't put them on output
[04:21:05] <The_Vulture> mohadib: look at the example I gave, if two appears more than once on input, it doesn't appear _at all_ on output
[04:21:43] <The_Vulture> If you say, only add an element once, and don't add it again if it's already there, then you still get it at least once on output
[04:22:00] <The_Vulture> Alternatively if you remove an element when you see it a second time, then you still get it on output if you have an uneven number of duplicates
[04:22:00] <mohadib> yes but you can remove the elament if iyt is contained
[04:22:13] <The_Vulture> but then if there's a 3rd, your approarch breaks
[04:22:22] <mohadib> if(l.contains(e){ l.remove(e)}
[04:22:40] <The_Vulture> because you already removed the first when you saw the second, and so you add the 3rd because it doesn't appear in the list at all at that point
[04:22:51] <mohadib> The_Vulture: good point
[04:22:56] *** forsaken has quit IRC
[04:23:03] <mohadib> so a map sems the best
[04:23:11] <rake> The_Vulture, is it possible to use input from .io without implementing try and catch altogether?

[04:23:35] <javabot> rake, exceptions is http://java.sun.com/tutorial/essential/exceptions
[04:23:36] <The_Vulture> rake: standard input in Java's an unnecessarily complex task, so no - there's no real way to do it without some understanding of exception handling

[04:29:07] <hobbsc> if I use the final keyword, should I place it outside of my first class?  I'd like to use a named constant in main
[04:29:24] <hobbsc> that is, should it follow my import statements?
[04:29:31] <The_Vulture> hobbsc: that doesn't make sense..
[04:29:31] <Garibaldi> no
[04:29:36] <Garibaldi> there are no global variables
[04:29:37] <The_Vulture> you can't declare variables outside classes
[04:29:49] <hobbsc> er
[04:29:59] <hobbsc> I mean just outside of my main method, I got confused,
[04:30:00] <hobbsc> sorry
[04:30:13] <Garibaldi> anywhere in class scope
[04:30:18] <hobbsc> ok, thank you
[04:30:26] <The_Vulture> you could declare it there if you want. The general rule is that a variable should have the least scope necessary
[04:30:37] <The_Vulture> so if you aren't using it outside main, you probably shouldn't declare it outside main
[04:31:06] <hobbsc> that makes sense
[04:31:35] <vinse> hobbsc: a common practice is to create a class called Consants where you declare the final variables as static ... you then improt that class where needed and use Constants.VARNAME
[04:31:46] <hobbsc> I thought that named constants would be easier to use while I'm testing a program, as I can just change their values at the top of the file and not have to change multiple instances.
[04:31:59] <hobbsc> that's a good idea, I'll keep that in mind

[05:53:45] <mohadib> d03boy: use a bianry search
[05:53:53] *** MrPrimate has joined ##java
[05:54:19] <d03boy> i'm testing a few things: Lookup (custom class), TreeSet, HashMap, and LinkedHashMap
[05:55:06] <d03boy> i cant figure out why an ArrayList (from the Lookup class) is behaving like this though
[05:55:17] <mohadib> LinkedHashMap are have constant time insetion , removell etc , but it also is fast to iterate and it reatins assertion order
[05:55:39] *** Amnesiac has joined ##java
[05:57:02] <d03boy> to run the contains method on ArrayList 100 times through a list with 8000 elements it takes nearly 200ms, but it only takes 35ms for 10000 elements
[05:57:26] <slava> because hotspot compiles methods that are called frequently
[05:57:40] <d03boy> slava, can you elaborate a little?
[05:57:53] <d03boy> it stores the halfway point maybe?

[06:16:23] <d03boy> is it bad when all of my comparisons of arraylist, treemap, hashmap, linkedhashmap look almost exactly the same :|
[06:16:42] <dibblego> eh?
[06:16:57] <d03boy> i graphed their time complexities
[06:17:58] <dibblego> please make sense

[06:19:34] <MacIver> d03boy: have you ever done algorithm analysis?
[06:20:16] <d03boy> a little bit
[06:20:17] <MacIver> O(1) != O(n) != O(n^2)
[06:20:28] <d03boy> big-o notation, yes a little
[06:21:02] <MacIver> so, what is the cost of a remove in arraylist?
[06:21:06] <MacIver> in hashmap?
[06:21:17] <d03boy> i'm not testing remove, i'm testing add() and contains()
[06:21:28] <MacIver> ok, let's say contains
[06:21:40] <d03boy> an ArrayList is random access if I remember correctly
[06:21:42] <MacIver> what do you think it is for contains in an arraylist?
[06:21:46] <MacIver> random?
[06:21:52] <MacIver> it has to search through the list
[06:22:02] <MacIver> so it's O(n) time
[06:22:05] <dibblego> erm, no it doesn't
[06:22:09] <dibblego> ArrayList is O(1) seek
[06:22:13] <MacIver> dibblego: really?
[06:22:15] <MacIver> how so?
[06:22:17] <dibblego> truly
[06:22:19] <dibblego> so so
[06:22:25] <dibblego> LinkedList is O(n)
[06:22:29] <slava> you guys are idiots
[06:22:37] <MacIver> dibblego: how can it do that?
[06:22:39] <slava> MacIver is talking about contains(), not get()
[06:22:44] <dibblego> oh
[06:22:48] <MacIver> exactly!
[06:22:52] <MacIver> bah
[06:22:55] <dibblego> well shuddup then!
[06:22:57] <d03boy> it has to search through all of them :P

[07:51:32] <cybereal> vinse: in closing of emails
[07:51:34] <vinse> i also enjoyed how, when they were under any type of time pressure, they would always include the phrase "urgent" in the title

[07:52:06] <vinse> cybereal: yeah, that's how it sounds to me too
[07:52:16] <vinse> but to them it means "pls do whatever is necessary"

[08:10:51] <vinse> he really said that?
[08:10:54] <vinse> while in office?

[10:05:35] <Dewi> how do I tell which implementation of the java API I have installed? (fedora core 3)
[10:05:49] <Honk^away> java -version
[10:06:04] <Dewi> isn't that just the JVM?
[10:06:24] <Honk^away> is there a difference? :P
[10:06:33] <Dewi> with every non-sun implementation, yes
[10:06:49] <pr3d4t0r> Dewi: What are you running?
[10:06:59] <Dewi> on both these fedora core 3 machines, javac is from IBM
[10:07:05] <Dewi> and java is gij
[10:07:13] <Dewi> but I don't know what API (or "classpath") is on here
[10:07:16] <pr3d4t0r> Dewi: Sun certified Java systems come hand-in-hand with the libraries, etc. at the same release level.
[10:07:27] <Dewi> this isn't sun stuff
[10:07:28] <StarScream> morn
[10:07:35] <Honk^away> ibm's versioning is the same as suns, isnt it?
[10:07:40] <Dewi> I don't think any linux ships with sun stuff by default
[10:07:53] <pr3d4t0r> Dewi: Er... trash that GIJ stuff.  Use either IBM's or Sun's.
[10:08:00] <Dewi> yes.
[10:08:04] <Dewi> I may well do that
[10:08:11] <Dewi> but I need to be able to see what API it's using
[10:08:12] <pr3d4t0r> Dewi: When you do, don't install from RPMs.
[10:08:19] <Dewi> pr3d4t0r: why not?
[10:08:42] <pr3d4t0r> Dewi: Because RPMs are screwy.  Download the .bin file from Sun instead, chmod it to +x, then install that.
[10:08:43] <Dewi> you want me to use the instructions and .bin file from sun? is that what you mean?
[10:08:49] <pr3d4t0r> Dewi: Yes.
[10:08:52] <pr3d4t0r> Dewi: Less pain.
[10:08:59] <Dewi> except they are for "redhat"
[10:09:02] <Dewi> I'm running fedora
[10:09:02] <pr3d4t0r> Dewi: There are some queer RPM dependencies in the other one.
[10:09:06] <Dewi> at home I run debian
[10:09:07] <pr3d4t0r> Dewi: It doesn't matter.
[10:09:24] <pr3d4t0r> Dewi: It'll work on Linux systems of reasonably recent ilk.
[10:09:33] <Honk^away> gentoo's java-install stuff is pretty nice :)
[10:09:33] <Dewi> so I usually do convert the sun download into a package for my system
[10:09:36] <pr3d4t0r> Dewi: I just installed one on Mandrake.
[10:09:41] <Dewi> also you kind of need to do that to satisfy dependancies
[10:09:42] <pr3d4t0r> Dewi: Whatever works.
[10:09:50] <Dewi> otherwise no package requring java will install, generally
[10:09:51] *** d0gf has quit IRC
[10:09:58] <pr3d4t0r> Dewi: That's the point; the .bin file works fine without mucking with RPM dependencies.
[10:10:23] <Honk^away> pr3d4t0r: you may need java as dependency for other packages :)
[10:10:32] <Honk^away> (rpm sucks nevertheless)
[10:10:35] <pr3d4t0r> Dewi: Easiest install of them all.  1. run .bin file; 2. create symbolic links to the Java tools from /usr/local/bin or wherever; 3. ???; 4. profit!
[10:10:35] <Dewi> so how then do you install a java program shiipped as an RPM?
[10:10:55] <pr3d4t0r> Honk^away: If you don't install Java from RPMs, there is no dependencies.  Easy.
[10:10:59] <Dewi> it'll go "you don't have java installed". that's my main concern
[10:11:01] <pr3d4t0r> Dewi: I don't.
[10:11:16] <pr3d4t0r> Dewi: I go find the same program as a .tar.gz or disk image or whatever and install that instead.
[10:11:17] <Honk^away> pr3d4t0r: yeah, there's nothing to satisfy other dependencies either
[10:11:27] <Honk^away> pr3d4t0r: that's a pretty bad approach

[10:11:33] <Clackwell> hallo everyone
[10:11:34] <pr3d4t0r> Honk^away: No, it's not.
[10:11:39] <Honk^away> rpm sucks, but its still better than using no package manager at all
[10:11:40] <Honk^away> it is
[10:11:43] <Clackwell> hey pred
[10:11:45] <Dewi> for example I run azureus from a package, if I didn't package my java VM it would refuse to install
[10:11:46] <pr3d4t0r> Honk^away: No, it's not.
[10:11:49] <Honk^away> it is :)
[10:12:08] <pr3d4t0r> Honk^away: No, it's not.  I never had any Java software failed that was installed like that.
[10:12:12] <Honk^away> Dewi: if you wanna do it right, get apt ;)
[10:12:15] <Dewi> and sun doesn't distribute a package for a Free linux anyway
[10:12:21] <Dewi> Honk^away: damn straight
[10:12:26] <Honk^away> pr3d4t0r: so what?
[10:12:28] <pr3d4t0r> Honk^away: And I have some pretty major Java stuff running on my Linux boxes.
[10:12:29] <Clackwell> free linux?
[10:12:36] <Honk^away> you had to download and install every single java program yourself
[10:12:40] <Honk^away> including all dependencies
[10:12:41] <Dewi> Clackwell: they do redhat only
[10:12:47] <Honk^away> i just do emerge someprogram and it's there

[10:14:02] <pr3d4t0r> Clackwell: Indeed.
[10:14:09] <Honk^away> pr3d4t0r: you make your life more complicated ;)
[10:14:11] <Dewi> my original pragmatic question was how to identify which API "java" will use
[10:14:18] <Dewi> like is there some config file it checks
[10:14:20] <Dewi> or some dir it looks in
[10:14:26] <Honk^away> Dewi: java -version
[10:14:29] <Clackwell> what does "which api java will use" mean?
[10:14:30] <Dewi> or some environment variable I'm not currently aware of
[10:14:33] <Honk^away> if it's a proper jvm
[10:14:35] <pr3d4t0r> Honk^away: Let's put our success rate and pay cheques on the table and see who's getting more stuff done in less time, shall we?
[10:14:42] <Dewi> the JVM is not the API
[10:14:58] * pr3d4t0r is being a dick because he's tired.
[10:15:00] <cybereal> Dewi: the standard library is linked to the java spec version that the jvm supports
[10:15:03] <pr3d4t0r>  /kick pr3d4t0r
[10:15:05] <pr3d4t0r> Good night.
[10:15:14] <Dewi> cybereal: I don't have the standard JVM. I keep saying that.
[10:15:19] <Honk^away> Dewi: is there any jvm, that uses several java apis at once?
[10:15:20] * Clackwell senses linux modularization desperation, "everything's a module, the jvm, the api, everything!"
[10:15:25] <Honk^away> i dont think so
[10:15:28] <Dewi> how can I remove something to replace it with sun's one, as you recommend, if I have no way of looking up what I currently have installed?
[10:15:33] <Dewi> I don't even know its name to remove it!
[10:15:43] <Honk^away> Dewi: ibms jvm has proper versioning too
[10:15:48] <Honk^away> same with blackdown
[10:15:49] <Dewi> well this is gnu's
[10:15:50] <Clackwell> Dewi: just have the sun "java" and "javac" executables first in your path.
[10:15:52] <Dewi> at the moment
[10:15:55] <Honk^away> Dewi: screw that
[10:16:01] <Honk^away> it sucks
[10:16:02] <Honk^away> bad :P
[10:16:06] <Clackwell> while at it, consider an OS which you don't have to make guesses around when using.
[10:16:25] <Dewi> Clackwell: what the fuck OS is that?!
[10:16:34] <cybereal> Dewi: gnu's jvm classpath is worthless, it's not even up to 1.1 spec
[10:16:35] <Clackwell> starting several new things at once is a bit confusing, might make it more comlpicated than necessary.
[10:16:44] <Dewi> the only OS one doesn't have to guess about is an OS whose source you've read start to finish :P
[10:17:00] <Honk^away> and there's some stuff from higher java apis too
[10:17:08] <Honk^away> so you cant tell, no matter how hard you try :P
[10:17:09] <Clackwell> Dewi: windows for example. or any linux distro that doesn't install some fake "java" (like gcj, kaffe, etc.)
[10:17:25] <Dewi> I'm developing in windows, but I'm planning to serve JSP pages from linux
[10:17:37] <Clackwell> Dewi: i see
[10:17:47] <Dewi> so the windows situation where my IDE lives is, as you say, nice and simple
[10:17:53] <Honk^away> just dont use gcj ;)
[10:18:13] <Dewi> unfortunately I have inherited this server
[10:18:19] <Dewi> from an idiot
[10:18:23] <cybereal> install a real jre
[10:18:36] <Clackwell> Dewi: just have the sun "java" and "javac" executables first in your path. the respective jvm will automatically do the rest, use its own resources, api implementation, etc. (in case of sun java, anyway).
[10:18:45] <Honk^away> Dewi: even if you didnt have root, you could still set up suns java without problems
[10:18:56] <Dewi> Clackwell: I don't think that'll work unless the API implementation is in the location it expects
[10:19:07] <Dewi> like how does it locate it?
[10:19:33] <Clackwell> Dewi: you are wrong. it does work. i have used it many times. how does it locate where it itself is residing? ask sun that.
[10:19:58] <Clackwell> there is some path traversing trickery, if i recall correctly, on linux.
[10:20:04] <Honk^away> btw, Dewi: http://gcc.gnu.org/java/faq.html#2_1
[10:20:05] <Honk^away> =)
[10:20:19] <Clackwell> PATH traversing, rather.
[10:20:32] <Dewi> so what you're saying is that if I install java on a network drive on the moon, as long as "java" and "javac" are in my path, it'll fly to the moon automatically or establish whatever link it needs to to find the API jar?
[10:20:36] <Honk^away> Dewi: java can be installed wherever you want
[10:20:36] <Dewi> (s)
[10:20:45] <Honk^away> Dewi: yes
[10:20:49] <Honk^away> absolutely right
[10:20:55] <Clackwell> Dewi: as long as the moon is mapped into the filesystem, yes.
[10:21:04] <Dewi> sounds like my hope of uninstalling GNU classpath is hopeless then
[10:21:10] <Dewi> since it will seek it out across all time and space
[10:21:16] <Dewi> what hope do I have of removing it?
[10:21:22] <Clackwell> "oh, i got started. let me check the path to find my location in the filesystem. all my other files must be there, too."
[10:21:30] <Honk^away> Dewi: suns jvm wont meddle with the gnu stuff at all
[10:21:49] <Clackwell> Dewi: no need to uninstall GNU classpath.
[10:21:56] <Dewi> software tends to get confused if more than one thing called "java" is in the path, in my limited experience
[10:22:15] <cybereal> Dewi: first on on the path is used
[10:22:19] <Honk^away> Dewi: that's not true
[10:22:22] <Clackwell> Dewi: that may be true for fucked up java variants. sun's isn't fucked up.
[10:22:30] <Honk^away> ibms isnt either
[10:22:39] <Honk^away> gcc definitely is
[10:22:45] <Dewi> I've had things pop up and ask me which implementation to use
[10:23:01] <Clackwell> Dewi: that's due to your moronic linux distro probably.
[10:23:01] <Dewi> so anyway, it's some relative path thing
[10:23:07] <Dewi> Clackwell: nah this was in windows
[10:23:16] <Dewi> didn't have any linux at that job
[10:23:18] <cybereal> that's normal, if the applicatino supports checking for such things
[10:23:24] <cybereal> jre
[10:23:29] <Clackwell> Dewi: then it is PEBKAC or not plain java applications.

[10:23:53] <Clackwell> cybereal: yeah
[10:24:00] <Honk^away> that wont "fuck up" anything though
[10:24:06] <Clackwell> not the "java" command bringing up any popups.
[10:24:06] <Honk^away> it's actually pretty convenient
[10:24:12] <Clackwell> it is useful to keep such things apart.
[10:24:15] <cybereal> but it is irrelevant when java <args> is how you started your app
[10:24:19] <Clackwell> so you can put blame more accurately.
[10:24:39] <Honk^away> and dont mix linux with windows :P
[10:24:59] <Dewi> Honk^away: I'm the worst kind of offender there

[10:26:54] <Clackwell> Down`: consider channels concerning themselves with web stuff.
[10:26:56] <Dewi> Down`: read about javascript
[10:27:01] <cybereal> bash is close to acceptable but, if ... fi? heheh

[10:28:04] <Down`> Dewi thx ;> but I can't find a fine tutorial.

[10:29:07] <cybereal> Dewi: do your homework and you'll find those tools
[10:29:31] <Clackwell> Dewi: developers sometimes have a disturbed sense of good and bad. assuming you are not one of them, sure, give the java web world a try. be prepared for having to wade through 1001 choices for every little piece you need.
[10:29:48] <Dewi> I wrote web apps in a cocoon clone for 9 months, so now I want to try the real cocoon
[10:29:58] <Clackwell> Dewi: any decent java/.net developer should cope well with .net/java in my opinion.
[10:30:01] *** roots- has joined ##java
[10:30:07] <Clackwell> if he doesn't, he sucks and should probably stick to what he knows already.
[10:30:12] <Dewi> (becuase the aforementioned clone is closed source and unavailable anymore)
[10:30:46] <roots-> Clackwell old house
[10:31:03] <Clackwell> Dewi: you may not find many cocoon users here, not often asked for. might ahve to use their mailing list to get in touch with people using it, efficiently.
[10:31:08] <Clackwell> hi roots-doods :)
[10:31:23] <Clackwell> ah, just recalled, it's monday, right? :)
[10:31:32] <roots-> the day i dont like
[10:31:39] * Clackwell enjoys his first proper vacation since 1+ years
[10:31:42] <grifis> Clackwell: i need to receive a variable number of bytes two times with in.read()... The first time i receive also a lot of bytes from the second's send
[10:31:49] <roots-> Clackwell: i had 1 week in the summer
[10:32:01] <roots-> still have 5 weeks plus 4 days left for this year to take
[10:32:28] <roots-> Clackwell: but you work parttime right ?
[10:32:31] <Clackwell> grifis: the bytes that you send are received as a stream, always. it is up to your code to keep them apart. nothing on the sending site will automatically do that for you.
[10:32:40] <KingNato> Concurrency gives me headaches
[10:32:54] <roots-> KingNato: stick to patterns that work
[10:33:10] <Dewi> hmmm
[10:33:15] <Dewi> looks like a storm is about to hit
[10:33:15] <Clackwell> roots-: officially did, practically didn't for +1 years. now we switched the contract over to full time. so better pay for about the work on the bottom line.
[10:33:18] <roots-> eg almost all of concurrent/multithreaded apps work based on an eventqueue with consumer/producer threads
[10:33:21] <Dewi> I'm going idle to drive to another geographic location
[10:33:23] <Dewi> thanks for the advice ghuys
[10:33:26] <Dewi> much appreciated
[10:33:39] <Clackwell> Dewi: good luck with tomcat and the java web world
[10:33:52] <Dewi> thanks
[10:34:00] <Clackwell> may the java gods not frustrate you too much with their usual wanking :)
[10:34:01] <Dewi> bbl
[10:34:06] <Dewi> hehe
[10:34:10] *** chippy has joined ##java
[10:35:10] <KingNato> roots-: Easier said than done when dealing with an existing codebase of several hundred thousand lines of code :(
[10:35:23] <roots-> indeed
[10:36:42] <roots-> but its not that hard to get into other people's code as it seems when you first see it
[10:36:48] * KingNato would like to try writing something major in Erlang at some point, to see how much it helps with cuncurrency
[10:36:57] *** chippy has quit IRC
[10:36:58] <roots-> take a while to get familiar with a program and some programs are so chaotic
[10:37:27] <cybereal> KingNato: erlang's threads are not able to run in seperate processors are they?
[10:37:56] <KingNato> cybereal: They aren't threads, but you can have processes on different CPUs or even machines
[10:38:04] <Clackwell> roots-: however there will often be that sick feeling that the authors of the code did their best to favor indirect, obscure, complicated choices and design decision rather than the straightforward ones.
[10:38:43] <roots-> Clackwell: hardly ever
[10:38:53] <roots-> if you did that and have any decent skills it would indeed become impossible
[10:39:08] * KingNato points everyone who doesn't know it already to http://thedailywtf.com/
[10:39:11] <roots-> code looks like its been intentionally scrambled soon enough
[10:39:14] <KingNato> It cheers me up immensely :)
[10:39:30] <roots-> just by adding a few special cases and a few strange lines
[10:39:41] <Clackwell> roots-: taking the most obvious turns requires yearas of training and a lot of feedback with other developers about great amounts of your code.
[10:39:47] *** chippy has joined ##java
[10:39:50] <roots-> if you really designed for no-maintenance it really becomes like thta too
[10:40:05] <Clackwell> i doubt many people have that ability. so i expect every code to be fucked up.
[10:40:07] <roots-> Clackwell: not true, just read "code complete"
[10:40:37] <roots-> 2nd edition, its full of down-to-earth advises on how to make code readable
[10:40:46] <Clackwell> roots-: yes, the problem is that the author hasn't read it...
[10:40:47] <roots-> could even be extracted to a 3 page documented
[10:41:02] *** dibblego has joined ##java
[10:41:07] <Clackwell> so he will apply different thinking than you will (he will anyway, at least slightly).
[10:41:32] <roots-> eg. favor the nominal case in conditionals, favor positive cases, avoid deep nesting, use standard naming, use standard idioms
[10:41:50] <roots-> Clackwell: nope, i agree 100% with all that is written in code complete
[10:41:55] <Clackwell> if you "normalize" every developer to sanity and proper design choices by reading a book, that would be great of course. but it sounds delusional.
[10:42:03] <Clackwell> +can
[10:42:22] <Clackwell> it defies human nature, doesn't take ego, playfulness, etc. pp. into account.
[10:42:28] <roots-> it isn't, its just people don't realize the book exists and some thing the advice is trivial
[10:42:34] <roots-> be that as it may, it is still correct
[10:42:36] *** pulaski has quit IRC
[10:42:49] <roots-> Clackwell: code complete touches these subjects as well
[10:43:02] <roots-> psychocological soft factors
[10:43:25] <Clackwell> i still doubt that by simply reading about things people will realize what the proper choices are.
[10:43:43] *** christo has joined ##java
[10:43:51] <roots-> not in every single aspect
[10:43:56] <roots-> but overall ... yes
[10:44:57] <Clackwell> everyone has read about speeding leading to accidents and deadly injuries, right? everyone knows that getting as close as a few meters behind another car on the autobahn at speed 160+ km/h is very dangerous, right?
[10:45:07] <dibblego> no, this is false
[10:45:18] <dibblego> reality is counter-intuitive
[10:45:19] <Clackwell> i believe that it is human nature to make the wrong choices despite better knowing.
[10:45:21] <Clackwell> hi dibble.

[10:45:32] <dibblego> hey mate
[10:45:43] <roots-> Clackwell: yes, but that depends on nationality
[10:45:51] <roots-> eg. dutch people can't drive :>
[10:45:51] <Clackwell> roots-: oh? ;)
[10:45:55] <Clackwell> haha :)
[10:46:09] <roots-> portugese are the best driver by natural selection
[10:46:21] <roots-> the not so good ones die :) (ever drove in portugal ?)

[10:55:24] <dibblego> there are third parties though
[10:55:34] <dibblego> or you could spend 30 seconds writing it yourself :)
[10:55:45] <roots-> it takes 5 minutes
[10:55:47] <dibblego> I did, but it's proprietrary, sorry
[10:55:55] <sinister_> :(
[10:55:58] <sinister_> thanks anyway
[10:56:00] <roots-> i wrote it about 10 times
[10:57:04] <dibblego> you were bored the other 9?
[10:57:59] <dibblego> the anaesthetic is wearing off on my toe
[10:58:09] <roots-> c and c++ and over and over again
[10:58:31] <roots-> anyhow for java you can find non accessible impl. in the core lib
[10:58:45] <roots-> sinister_: do you use eclipse ?
[10:58:57] <sinister_> No
[10:58:57] <dibblego> yes, you usually can for the Sun and IBM implementations
[10:59:00] <sinister_> I use pico
[10:59:17] <roots-> bleeding edge
[10:59:23] <dibblego> better to use a third party than to tie to an implementation though

[11:01:20] <Honk^away> zz_: use iconv or whatever tool there is for your system
[11:01:25] <zz_> BULLE: well, that just popped into my mind. is there another way to do it?
[11:01:26] <BULLE> Honk^away: indeed

[11:01:43] <zz_> BULLE: im on a windows box
[11:01:47] <BULLE> oh
[11:01:48] <roots-> so what ?
[11:01:49] <Cutt> I'm looking for someone that had experience with jspWiki (exchanging infos)
[11:01:52] <roots-> i am on a windows box too

[11:01:57] <roots-> i have iconv, recode

[11:02:13] <BULLE> roots-: i bet you are using cygwin or similar ?
[11:02:24] <roots-> BULLE: cygwin yes
[11:02:33] <Honk^away> zz_: that's what the "or whatever tool there is for your system" was talking about
[11:02:35] <roots-> but everyone uses it
[11:02:38] <Honk^away> just search some tool that does it for ya
[11:02:43] <Honk^away> or install one :)
[11:02:56] <zz_> iconv in cygwin will work u think?
[11:03:02] <Honk^away> sure
[11:03:03] <roots-> zz_: yes it will
[11:03:13] <zz_> sweet
[11:03:25] <roots-> its a frontend for libc's iconv function
[11:03:47] <roots-> glibc
[11:04:11] <Honk^away> iconv sucks though :P
[11:04:28] <zz_> as long as my project won't be stuffed up... else my neck's on the chopping block
[11:05:11] *** Aquila_Deus has quit IRC

[11:05:20] <roots-> well you want to make a backup first
[11:05:23] <roots-> so much is for certain
[11:06:01] <Honk^away> iconv needs a switch to replace the original file :p
[11:06:13] <roots-> is that good or bad ?
[11:06:14] *** pavlicek has quit IRC
[11:06:20] <roots-> in zz_'s case it might be good
[11:06:31] <Honk^away> iconv needs a switch to write to some file at least
[11:06:44] <Honk^away> or to write a copy to some directory you specify
[11:06:58] <Honk^away> stdout always requires some extra work from the user :p
[11:07:50] <zz_> Honk^away: what do u mean by switch?
[11:07:56] <Honk^away> commandline switch
[11:08:16] <zz_> what's that>/
[11:08:17] <zz_> ?
[11:08:31] <Honk^away> foo -bar
[11:09:26] <Honk^away> to make iconv write to files, one always has to pull tricks like using find+a 1 line shell script ;)
[11:09:46] <Honk^away> having some cmdline switch would be more convenient

[11:14:24] <Honk^away> a shell doesnt exactly take long to start

[11:55:40] <roots-> that sucks more
[11:55:47] <roots-> trust me, file locking on shared drives etc is trouble

[11:56:33] <eythian> harder and harder.
[11:57:02] <eythian> I suppose I could just give in and read the Azureus source.
[11:57:05] <eythian> see how they do it
[11:57:18] <roots-> most apps use sockets
[11:57:21] <roots-> eg emacs

[13:23:51] <terence_> how shall i do that at a list?
[13:25:19] <terence_> paulweb515:   how?
[13:25:33] <paulweb515> Implement Comparator#compare(Object o1, Object o2) ...
[13:26:42] <paulweb515> A set is not a list
[13:27:31] <paulweb515> You can sort an array (like String[]) using java.util.Arrays ... check it out
[13:28:21] <terence_> more easy paul, just for loop from 0 to site of list
[13:28:27] <terence_> ^size
[13:29:32] <terence_> Implement Comparator#compare(Object o1, Object o2) ...? how to set the new compertor class at set interface?
[13:31:16] <terence_> ahh the items have to implement comparable..
[13:33:26] <paulweb515> Not really, then you can call Arrays.sort(Object[], Comparable) ... the compare() method takes 2 objects, and has to decide which is "less"

[14:28:34] *** littlezoper has joined ##java
[14:29:21] <[algo]> any XML-RPC users ?
[14:30:47] *** hatOFF has joined ##java
[14:30:50] <Clackwell> [algo]: what is an exception stack?
[14:31:16] <Clackwell> [algo]: if in doubt, create an Exception and use it's methods, etc. pp., details at api docs
[14:31:27] <[algo]> hmm how ?
[14:31:32] <[algo]> I'm making XML-RPC request
[14:31:36] <[algo]> from non-java server
[14:31:40] <[algo]> to java-machine
[14:31:45] <Clackwell> ~enter
[14:31:46] <javabot> Don't press return until you've finished typing your question, it's annoying to see multiple lines for one question, and hard to follow.
[14:32:24] <[algo]> I'm making XML-RPC request from non-java server to java-machine. In the case of exception, only its Message is returned, but I'd like to see the whole stack: what happened.
[14:32:59] <Epesh> [algo]: the server doesn't know?
[14:32:59] <Clackwell> [algo]: no clue what you mean. if in a piece of code of mine i want a stacktrace, i create an exception and use its methods to get the stack elements, etc. pp. or, in case i caught an exception, i use that instead.
[14:33:36] *** heanol has quit IRC
[14:34:17] <Clackwell> [algo]: you want the complete details of an exception that occurred on the server-side available on the client?
[14:34:33] <Epesh> Clackwell: ... that he server doesn't expose...
[14:34:58] <[algo]> Clackwell: a nicer way would be to store erroneous request/response pair at server error log
[14:35:18] *** heanol has joined ##java
[14:35:19] <Clackwell> [algo]: and it doesn't? why did you write it so that it doesn't log the error completely?

[14:37:20] <[algo]> ClackWell: Does it log it somewhere ?
[14:37:26] <[algo]> Clackwell: I'm using Apache XML-RPC
[14:37:27] <Clackwell> [algo]: it doesn't?
[14:37:32] <[algo]> Clackwell: couldn't find
[14:37:51] <Clackwell> [algo]: apache xml-rpc is an xml-rpc server? i assumed it was a client lib.
[14:38:07] <Clackwell> [algo]: i would use the apache xml-rpc mailing list.
[14:38:18] <Epesh> Clackwell: yes, it's a server lib too
[14:38:29] <Clackwell> Epesh: i see
[14:38:31] <[algo]> Clackwell: it is both client and server
[14:39:01] <Clackwell> [algo]: catch, log and throw on the error inside your own server code that you add to apache xml-rpc?
[14:39:53] <[algo]> well, I'll dig into xml-rpc now and try to override what I need
[14:40:07] <Clackwell> override?
[14:40:21] <[algo]> catching occurs inside xml-rpc code
[14:40:28] <[algo]> written by apache
[14:40:38] <Clackwell> [algo]: why rely on that? catch in your own code
[14:40:40] <[algo]> (or whomever ;) )
[14:41:28] <[algo]> Clackwell: thanks, I'll look into it

If it fails, it finds a free port, starts a server itself, and writes out a file with the port number. It seems to work pretty well.
[16:33:34] <roots-> its a common approach afaik
[16:34:18] *** Mazon is now known as mazon
[16:34:35] <eythian> yeah. I talked to someone else, and dug through the Azureus code, and they all said the same thing (although Az just has one port number, which isn't so nice)

[16:35:09] <roots-> but hey, lets not discuss it:)

[17:46:13] <eidolon> gotta find a swing guru.
[17:46:15] <eidolon> like roots-  :)
[17:46:33] <roots-> eidolon: i am not a swing guru, but whats the question anyhow ?
[17:46:36] <mmr> roots-: you should go for the SCEA exam.
[17:47:10] <roots-> thats the top one right ?
[17:47:14] <eidolon> heh.  synic's app is doing something odd - every once in a while the JTextArea will stop updating completely... no exceptions thrown, no nothing.  just no text sent to it appears.
[17:47:16] <roots-> that would cost a fortune man
[17:47:32] <HelloWorld82> and SCEA is also very hard.
[17:47:39] <roots-> that could be caused by a lot of things
[17:47:39] <eidolon> but i seem to be the only one experiencing it :)
[17:48:01] <mmr> roots-: you should be able to afford it
[17:48:14] <eidolon> i've had had it happen in the middle of conversations - text is updating fine, then i notice nothing has appeared ofr a while.
[17:48:14] <mmr> java programmers are known to be well paid
[17:48:18] <eidolon> (jabber client)
[17:48:21] <roots-> mmr: are they ?
[17:48:41] <mmr> roots-: above the average, yes
[17:48:43] <HelloWorld82> at least better as PERl/CGI programmer :)
[17:49:24] <KingNato> I'm certainly making more money now writing Java than I did five years ago writing PHP :)
[17:49:27] <mmr> roots-: you probably can make your company pay the exam for you (if you pass, of course)
[17:49:39] <roots-> mmr: i doubt it
[17:49:43] <roots-> then again, its step by step
[17:49:47] <HelloWorld82> and it is not soooo expensive I think
[17:49:52] <roots-> i first need to take the developer, wouldnt i ?
[17:50:01] <mmr> roots-: no

[18:39:33] <Geren> Epesh, so why can't i declare it to be static in my method?
[18:39:59] <Epesh> because methods aren't class-level constructs. Declare it OUTSIDE of the method.
[18:40:12] <hd420> joaopaulo: private static ArrayConsulta arrayConsulta outside the method, but in the class

[19:14:04] <Clackwell> ("what's PATH?")
[19:14:08] <dmlloyd|work> it's a good idea to know what you're installing when you're installing it
[19:14:14] <dmlloyd|work> and that includes where it puts things
[19:14:27] <dmlloyd|work> if you don't do that, you've got no business running linux imo
[19:14:42] <dmlloyd|work> or rather, the distro that you're choosing to run

[19:43:30] <mohadib> well , he is not a PHB
[19:43:49] <mohadib> in my mind PHB is reserverd to clueless people who dont realize they are clueless
[19:44:03] <Clackwell> mohadib: not only is he several times as productive as we are, everything he does makes sense. 90%+ rate of sanity. the average joe programmer gets close to 50% sanity, in my experience. :)

[20:26:28] <IseeIsee> if I want to make a decision based on the selection inside a JComboBox, should I implement an ActionListener for it or an ItemListener ?
[20:26:41] <mohadib> ActionListener is better imho
[20:26:56] <mohadib> item listener will send you deselect events and select events
[20:26:57] <ernimril> IseeIsee: does not really matter, ActionListener is easier to implement

[20:51:08] <degWORK> if you wish to have a "File|Exit" menu item in an applet, and since you cannot use System.exit() for applets, what is a good method for effectively killing or stopping the applet
[20:51:28] <degWORK> believe it or not the java tutorial didnt help much other than to say that you cannot use System.exit()
[20:51:33] <ernimril> degWORK: 1) you do not want to have a menu inside an applet
[20:51:35] <Epesh> uh.. what would file/exit do in an APLET?

[20:53:21] <degWORK> it would be nice to catch this signal in other words
[20:53:32] <degWORK> and have some exit strategy
[20:53:50] <Lars_G> it's easy, your window should have a little "x" to the top right.....
[20:53:51] <degWORK> like displaying "Done." in the browser applet pane
[20:54:12] <degWORK> but I am already using menu items for printing and help features

[21:04:16] <Cow_woC> :)
[21:04:20] <Cow_woC> cheeser: I need some DAO advice
[21:04:22] <shredstar> no trolls on monday.
[21:04:37] <Cow_woC> ugh, don't remind me it's Monday :)
[21:05:12] <cheeser> what's up?
[21:05:29] <Cow_woC> cheeser: I wanted to add DAO.valueOf(property1, property2) to construct new objects like say ImageDAO.valueOf() returns an Image. If the Image already exists in the DB, it returns the canonical instance, otherwise it returns a new instance
[21:05:44] <Epesh> haha
[21:05:47] <cheeser> that's not what a DAO should be doing, but ok.  8^)=
[21:05:50] <Cow_woC> cheeser: first, I was told this is good design for canonicalization...
[21:05:56] <Epesh> Cow_woC: why not use a repository for that?
[21:05:58] <Cow_woC> was the guy wrong? is there a better way?
[21:06:03] <Cow_woC> Epesh: what do you mean?
[21:06:09] <cheeser> i'd put that logic in the manager/home layer.
[21:06:20] <Epesh> I'd not bother. I'd use JCR.
[21:06:22] <Cow_woC> what is the manager/home layer (I've asked this before but I forget)
[21:06:23] <Cow_woC> ?
[21:06:30] <Cow_woC> Epesh: what is JCR?
[21:06:32] <cheeser> get(); if(null) { create(); save(); } return;
[21:06:44] <Epesh> cheeser: transactionally?
[21:06:52] <cheeser> Epesh: sure
[21:06:53] <Cow_woC> cheeser: right, that's basically what I have, but in my DAO
[21:07:11] <cheeser> Cow_woC: yeah.  the DAO should only be used for the get()/save() bits
[21:07:22] <Cow_woC> cheeser: what's wrong with putting this in the DAO?
[21:07:44] <Cow_woC> I am using the DAO for all methods related to X (such as Theme, Image) that require the use of Session
[21:07:51] <cheeser> Cow_woC: well, the DAO is meant to access the datastore layer.
[21:07:59] <Cow_woC> cheeser: yes, but this is related ot the database
[21:08:16] <cheeser> only peripherally
[21:08:24] <Cow_woC> get() in your example is actually a Query
[21:08:29] <IseeIsee> if I want to forcebally exit a thread, what can I do ?
[21:08:29] <cheeser> i know it is.
[21:08:38] <cheeser> IseeIsee: terminate the run()
[21:08:39] <Cow_woC> well anyway, the problem is this...
[21:09:00] <IseeIsee> how can I terminate the run ?
[21:09:18] <cheeser> IseeIsee: stop doing work in it.
[21:09:20] <Cow_woC> cheeser: In my old code, I have lazy image rescaling, so if you invoke image.getScaledImage(newDimensions) it'll return Image2. Image2's data is only scaled when it's absolutely required
[21:09:21] <cheeser> terminate the loop.
[21:09:55] <Cow_woC> cheeser: because "data" makes up the canonical part of the Image in the DB, this means that the Image object changes after being constructed, which is bad because canonicalization goes out the window
[21:09:57] <Cow_woC> cheeser: ideas?
[21:10:22] <shredstar> Epesh: well, duh. thx, i should have known that.

[21:11:53] <shredstar> Im using the ktable.sourceforge.net project to add a table to my SWT app. Its pretty cool - and very fast. Smart guys.
[21:11:54] <Cow_woC> cheeser: the lazy scaling method seems to be incompatible with the getCanonicalInstance() pattern
[21:11:55] <{aaron}> Cow_woC: is it scaled on-demand, or by some background thread/process?
[21:12:01] <Cow_woC> {aaron}: scaled on demand
[21:12:24] <Cow_woC> {aaron}: getScaledImage() returns an image that is theoretically scaled but it will only get scaled when getData() is invoked
[21:12:48] <{aaron}> and you don't want two threads callign getScaledImage, and having the processing occur twice, right?
[21:13:21] <{aaron}> i think you just need to use a lock on the scaling process for a given image to ensure another caller gets the "canonical" scaled image
[21:13:23] <Cow_woC> not exactly. I don't want image.getScaledImage() invoked, then the data never used but an expensive scaling occurs
[21:13:32] *** ocx32 has joined ##java
[21:13:39] <{aaron}> why would getScaledImage get invoked if the data is not used?
[21:13:48] <Cow_woC> {aaron}: <shrug> it happens
[21:14:06] <Cow_woC> at least from memory it did
[21:14:09] <{aaron}> by the way, the way I implemented this is that the scaled image is simply a field on an object, requesting it queues an *asynchronous* scaling operation
[21:14:10] *** putzel has joined ##java
[21:14:14] <Cow_woC> when I added lazy scaling my performance shot way up
[21:14:16] <{aaron}> when the scaling operation is complete it /resets/ the field
[21:14:16] <yi> if your input doubles and the time to process that doubles as well
[21:14:22] <yi> your complexity is linear right?

[21:14:47] <Cow_woC> yi: I think :)
[21:14:50] <Stork> is it possible to make a class that extends bufferedwriter, that would encrypt the data that it writes?
[21:14:52] <yi> Cow_woC: hehe
[21:15:09] <ocx32> hi guys, i have 2 classes that extend jframe ( they have gui interfaces) i am trying to create an instance of each of these classes in a main program ( a third file) in order to display the 2 frames at the same time. i am not able to see anything inside the frames when called. just empty frames
[21:15:12] <Stork> i have the encryption methods
[21:15:15] <Cow_woC> yi: the way you phrased it is confusing
[21:15:21] <{aaron}> Stork, Cow_woC, yi: well, if the time to process is a *constant* (regardless of whether it is "double"), then it's linear
[21:15:32] <Cow_woC> yi: the way I'd phrase it is: if the number of inputs doubles, the amount of time spent processing them doubles too
[21:15:36] <Cow_woC> complexity remains the same
[21:15:50] <jcscoobyrs> wig: Yes you can.
[21:15:50] <ocx32> i am including getContentpane(panel) in each of these files but not in the main one

[22:11:58] <IseeIsee> primitives are serializable by default ?
[22:12:08] <cheeser> in the method called by the listener, you update frame2
[22:12:12] <cheeser> IseeIsee: yes.
[22:12:17] <cheeser> javabot: tell IseeIsee about serialization
[22:12:17] <javabot> IseeIsee, see http://java.sun.com/docs/books/tutorial/essential/io/serialization.html and http://www.antwerkz.com/antwerkz/articles/serialization/index.jsp
[22:12:56] <ocx32> cheeser: can u please explain to me the concept?
[22:13:50] <ocx32> i am really confused, i am seeing an example in which frame 1 implements an interfance ListenerTest() and frame 2 calls that listener in the actionperformed
[22:14:00] <ocx32> i didnt understand the concept
[22:14:38] <Lars_G> ocx32: Basically, implementing an interface, means you will provide the methods required by that interface's design.
[22:14:41] <ocx32> frame 2 is creating an instance of the interface and calling the method
[22:14:52] <ocx32> but method is only defined, no body
[22:15:09] <Lars_G> ocx32: You do not apply an interface to use it yourself (normally) but to let classes who use these interface methods know you can handle them, and serve theyr calls.
[22:15:14] <IseeIsee> ocx32: you may not get clear understanding of interface by reading 2 or 3 lines here, you'll need to go through a tutorial

[22:17:20] <ernimril> HelloWorld82: ask your question and find out if anyone want to help you
[22:17:35] <HelloWorld82> I have a JPanel, in which I allows several pluggins to draw. From a combobox, I can select which pluggins will draw now. For example : First, I select plugginA, and plugginA draws. Then I select Plugginb, PlugginA stops drawing, and PlugginB draws .
[22:17:36] *** npmccallum-work has quit IRC
[22:18:07] <HelloWorld82> and alle pluggins are also Subtypes of JPanel
[22:18:19] <HelloWorld82> I implemented it as follow, but it doesn't work :
[22:18:34] <HelloWorld82> ViewerPanel.remove(plugginA);
[22:18:34] <HelloWorld82> ViewerPanel.add(plugginB);
[22:18:46] <HelloWorld82> yes ... I think, I made something bad :)

[22:19:24] <HelloWorld82> Then I select an other pluggins some part of the main panel (The viewer Panel) are not visible anymore.
[22:19:31] <ocx32> the thing i am not understanding in the file4

[22:19:57] *** Mot has quit IRC
[22:21:35] <cheeser> javabot: tell HelloWorld82 about jpf
[22:21:36] <javabot> HelloWorld82, jpf is the java plugin framework.  It aims to simplify plugin based systems and can be found at http://jpf.sourceforge.net/.
[22:23:03] <ulver> jpf is very cool
[22:23:18] <ocx32> <cheeser> can you please take a look at http://pastebin.com/404463 and tell me whats the use of setListener( in file4? i read the tutorial and i understood the concept but still i am confused by that example
[22:23:20] <HelloWorld82> sorry, I cannot swith to jpf now. It's to late, I have to finish my project at the end of the week
[22:24:04] <Lars_G> Hmmm jpf sounds interesting
[22:24:19] <HelloWorld82> and ... its not my problem. loading pluggins, with the name and class of the pluggin stored in a property file works nice (I will investigate jpf later) . My problem is a swing problem I believe

[22:58:57] <Stork> my goal is to make an EncryptedFileInput/OutputStream

[22:59:37] <Stork> essentially, one time padding
[22:59:48] <vinse> that's not encryption
[22:59:58] <vinse> well, maybe technically

[23:01:27] <Jax> (a link that is, not a primer here ;)

[23:01:43] <vinse> Stork: well, technically it is, but when i think of encryption i think of strong encryption ... your scheme is weak
[23:01:54] <IseeIsee> now neither of my classes has a BufferredImage data member, but when I write the main class which has all the other classes encapsulated in it, I get an expcetion that bufferredimage not serializable
[23:02:02] <mohadib> it's like the secret decoder ring that comes in ceral boxes
[23:02:20] <hashman> Jax, read the java tutorial by sun
[23:02:23] <IseeIsee> I'm using bufferedImage in the methods of the classes but non of my data member has a BufferedImage

[23:04:10] <hashman> ...
[23:04:43] <mohadib> and interfaces
[23:04:45] <mohadib> yaya

[23:05:27] <IseeIsee> please read my Question above, I'm dying to get its solution
[23:06:42] <Jax> ok, so an interface is basically the span of methods of an object?
[23:07:20] <mohadib> ~tell Jax about interfaces
[23:07:21] <javabot> Jax, interfaces is http://java.sun.com/docs/books/tutorial/java/interpack/createinterface.html
[23:07:53] <Jax> so yes
[23:07:58] <hashman> Jax, remember, you can use an interface as a type
[23:08:07] <hashman> this is the power of the interfaces
[23:08:09] * Jax ponders that statement for a moment
[23:08:29] <Jax> so the object will inherit all the methods of that interface?
[23:08:44] <hashman> Jax, implement
[23:08:48] <hashman> not inherit
[23:08:50] <mohadib> interfaces give you something akin to multiple inherityance and they assist with polymorphisim
[23:08:50] <Jax> ah yes
[23:08:54] <Jax> Java terminology ;)
[23:09:09] <Jax> i'll just have to hack away a bit..
[23:09:09] <hashman> Jax, an interface gives your object a way of how it must work
[23:09:17] <Jax> interesting concept.
[23:09:42] <Jax> i.e you can define an array of methods (an interface), and have multiple objects implement these
[23:09:47] <mohadib> Jax: i see it as a way to meet a contract with out forcing an unatural relationship
[23:11:04] <hashman> Jax, you can have an interface that will tell your object how to obtaint the number of objects, how to obtaint the first object, the last object...
[23:11:15] <hashman> this interface will be implemented by a Vector and a List
[23:11:37] <hashman> both Vector and List will have that methods, but the implementation will be totally different
[23:11:38] <hashman> BUT
[23:12:03] <hashman> we can make a method, in where we can send a type that it's the interface itselft
[23:12:10] <hashman> and we can send there both the Vector and the List
[23:12:17] <hashman> cause the interfaces can be used as types

[23:14:38] <Jax> you said "you can have an interface that will tell your object, how to obtain the number of objects..."
[23:15:08] <hashman> Jax, IMHO interfaces and generics are very very powerfull and one of the best and powerfull tools of java
[23:15:10] <Jax> you mean you have a parent object, and you are initializing child objects of this parent object, via the interface?
[23:16:00] <ocx32> can i have an interfANCE instance in the argument of a method?!!?!!?!
[23:16:03] <hashman> Jax,  there is no parent and childrens with interfaces, you just implements interfaces
[23:16:05] <ocx32> interface
[23:16:56] <ernimril> ocx32: "public void someMethod(SomeInterface sif) {...}" yes that is valid
[23:17:03] <shingoki> ocx32, an interface is a type, use it where you have any type
[23:17:29] <shingoki> there's a certain argument that any parameter of a method should ALWAYS be an interface
[23:17:42] <shingoki> except where Sun have already mucked it up for you by having no interface
[23:17:53] <shingoki> or primitives, obviously :)
[23:18:18] <hashman> shingoki ocx32, an interface is a type, use it where you have any type <= this is the power of interfaces, they can be used as types
[23:18:43] <ocx32> but
[23:19:03] <ocx32> the problem is how can i create an instance of an interface to call that method?
[23:19:20] <shingoki> ocx32, you create an instance of something that implements the interface
[23:19:44] <shingoki> "class A implements B" means that an instance of A can be used as a parameter of type B

[23:26:25] <talin> i have an instance of a DataInputStream... how can i check the amount of lines in it? because want to put each line in a String[]... so i need to know how big i have to make the string after i've read the file
[23:26:30] <veleno> thx everyone
[23:26:33] *** veleno has quit IRC
[23:26:40] <elirips> FaeLLe: thanks, i'll have a look at it.
[23:26:48] <mohadib> talin: you cant tell iirc
[23:26:57] <talin> mohadib: ah, hmmm
[23:27:00] <ernimril> talin: you can not, read the lines and put them in an List
[23:27:09] <talin> ernimril: ah, okay.
[23:27:09] <mohadib> talin: use a buffered reader if you like
[23:27:10] <talin> thanks
[23:27:17] <talin> mohadib: i am using a buffered reader
[23:27:31] <talin> mohadib: but i need to store each line in an array
[23:27:39] <mohadib> well , as ernimril said , use a list , it can grow
[23:27:57] <mohadib> then to can make it an array later
[23:27:58] <talin> ah, what kind of list do you recommend? i haven't used collections a lot
[23:28:05] <cheeser> ArrayList
[23:28:06] <mohadib> ArrayList
[23:28:10] <talin> okay, thanks
[23:28:12] <rogue-kun{B}> talin: and even if you really must move it into an array, List has a toArray fuction 8)
[23:28:12] <Stork> hey guys, what's the best way to read a (small) file into a byte[] ?
[23:28:13] <Amnesiac> hey mohadib, cheeser
[23:28:13] <mohadib> ~tell talin about collections
[23:28:13] <javabot> talin, collections is http://java.sun.com/tutorial/collections

[23:28:20] <talin> ah, great
[23:28:25] <mohadib> Stork: FileReader
[23:28:31] <Stork> cool, thanks
[23:28:57] <FaeLLe> talin: good luck :) its pretty simple tbh
[23:28:57] <mohadib> jhowdy Amnesiac :)
[23:29:04] <cheeser> hey Amnesiac
[23:29:09] <mohadib> FaeLLe: tbh?

[23:29:20] <cheeser> Stork: ByteArrayOutputStream
[23:29:28] <FaeLLe> mohadib: to be honest
[23:29:32] <mohadib> ahh
[23:29:33] <mohadib> ty
[23:29:40] <cheeser> ty?
[23:29:41] <cheeser> 8^)=
[23:29:43] <mohadib> heh
[23:29:44] <FaeLLe> anytime mate :)
[23:30:01] <rogue-kun{B}> cheeser ty = thank you
[23:30:01] <Stork> cheeser: i said to read a small file :\
[23:30:05] <shingoki> ArrayList might not be best for reading lines
[23:30:13] <shingoki> but it probably doesn't really matter :)
[23:30:16] <Amnesiac> Stork, what's wrong with BAOS to read small files?
[23:30:24] <Stork> it's an outputstream :\
[23:30:29] <shingoki> heh heh
[23:30:43] <mohadib> Stork: lol
[23:30:43] <Amnesiac> well to read just change the Out part to In
[23:30:49] <Stork> fair enough
[23:30:53] <Amnesiac> :/
[23:31:49] *** Tubbi3 has quit IRC
[23:31:59] * rogue-kun{B} ponders if ther is any Output clases with out a matching Input class in java
[23:32:29] <cheeser> javabot: tell rogue-kun{B} about sarcasm
[23:32:29] <javabot> rogue-kun{B}, I have *no* idea what sarcasm is.  I've *never* heard of it, because *I'm* just a stupid bot, aren't I.
[23:32:37] <Stork> what should i use as the buffer :|
[23:32:48] <mohadib> Stork: its that or arrayCopy
[23:32:51] <cheeser> Amnesiac: no.
[23:32:58] <mohadib> or you can get the length of the file and make a huge array
[23:32:59] <cheeser> Stork: read from file, output to BAOS
[23:33:08] <cheeser> when you're done, call toByteArray()
[23:33:10] <Stork> how do i read from file :o
[23:33:15] <mohadib> lol
[23:33:18] <cheeser> javabot: tell Stork about io
[23:33:18] <javabot> Stork, io is http://java.sun.com/tutorial/essential/io
[23:33:19] <mohadib> Stork:GOOGLE
[23:33:34] <Stork> BAIS ?
[23:33:54] <Amnesiac> heh
[23:34:03] <Stork> i know, i'm a noob
[23:34:34] <mohadib> ~ridicule Stork
[23:34:35] * javabot points at Stork and laughs.
[23:34:37] <mohadib> ;)
[23:34:42] * Stork dies
[23:34:57] * mohadib watches slava give Stork ass to mouth
[23:35:20] <Stork> hmm
[23:35:39] <Stork> the number of bytes i'd be reading is file.length(), right ?
[23:35:45] <mohadib> yes
[23:35:48] <mohadib> but read()
[23:35:55] <Stork> read() ?
[23:35:56] <mohadib> is flakey ime
[23:36:13] <mohadib> it does not quarante to read all at one time
[23:36:23] <mohadib> thats why read() returns the number it actually read
[23:36:31] <mohadib> cause you cant depend on it
[23:36:37] <Stork> so, which class would you recommend
[23:36:40] <shingoki> that's one way of putting it
[23:36:43] *** tezem has joined ##java
[23:36:51] <shingoki> its fairly standard for read and write methods to work that way
[23:36:52] <mohadib> shingoki: how would you put it?
[23:36:56] <Stork> at the moment, methinks fileinputstream ? except what you said about the read method..
[23:37:21] *** ulver has quit IRC
[23:37:41] * mohadib hates his job this week
[23:38:07] <tezem> anybody here who can say me the proper java regex for removing html tags? I have "<.*?>" but this doesn't remove tags which go over more than one line.
[23:38:25] * rogue-kun{B} gives mohadib a garfield I hate mondays sign
[23:38:36] <ernimril> tezem: it is still better to use a html parser
[23:38:44] <tezem> ernimril: ;-)
[23:39:05] <ernimril> tezem: do you use Pattern and Matcher or do you use String?
[23:39:20] <tezem> ernimril: Is a parser in the Java Standard API?
[23:39:24] <talin> hmm, i'm trying to use a Queue and it says "cannot find symbol".. i import java.util.* and i'm using 5.0
[23:39:26] <Clackwell> ~htmlparser
[23:39:26] <javabot> Clackwell, htmlparser is http://htmlparser.sf.net - it parses HTML.
[23:39:27] <tezem> ernimril: String
[23:39:38] <Clackwell> HTMLPARSER HTML Parsers (possibly handling dirty HTML): http://httpunit.sourceforge.net/ http://jwebunit.sourceforge.net/ http://htmlparser.sourceforge.net/
[23:39:54] <ernimril> tezem: I told you some time ago to use Pattern and Matcher if you use the regexp method
[23:39:55] <mohadib> Clackwell: hmmm dirty ay ... like from a cx or xxx domain?
[23:40:14] <Clackwell> mohadib: why, looking for ways to extract those images?
[23:40:26] <Clackwell> in fact - that would rock. :)
[23:40:43] <Stork> mohadib: is this right: http://rafb.net/paste/results/cqWlmn42.html
[23:41:14] <mohadib> Stork: not exactly
[23:41:19] <Stork> oh
[23:41:27] <Clackwell> Stork: http://javafaq.mine.nu/lookup?70
[23:41:54] <mohadib> Stork: use while() and look for -1
[23:42:00] <Stork> alright
[23:42:09] <Stork> but still use the read() method?
[23:42:09] <mohadib> and use the return from read() to know how much to write
[23:42:20] <Drone> That URL gave the following error code: 404 Object Not Found
[23:42:31] <Stork> what?
[23:42:48] <mohadib> Stork: yep   while((i = read(array , offset , len) != -1)
[23:43:04] <cheeser> or just rtflink that Clackwell posted
[23:43:06] <mohadib> the write i amount of bytes to BAOS
[23:43:11] <mohadib> yes
[23:43:18] <mohadib> ~tell me about spoonfedding
[23:43:18] <tezem> ernimril: but if I would use the Pattern and the Matcher I still don't know the proper pattern or do you mean that it doesn't work because it's a string regex?
[23:43:19] <javabot> mohadib, I have no idea what spoonfedding is.
[23:43:26] <mohadib> ;)
[23:43:26] <cheeser> javabot: tell mohadib about typing
[23:43:27] <javabot> mohadib, typing is smotheing i dno't konw how to do porprley

[23:45:46] <cheeser> and it's java.util
[23:45:56] <cheeser> the compiler told you java.utils.* doesn't exist.
[23:46:00] <cheeser> just read the compiler errors.
