[00:04:13] <redrebel> what is 'public static final long serialVersionUID = 1L'
[00:04:21] <whaley> ~~ redrebel Serializable
[00:04:21] <javabot> redrebel, Serializable is http://www.oreilly.com/catalog/javarmi/chapter/ch10.html
[00:04:46] <sproingie> that particular one means "make up a serialVersionUID based on some hash of class members"
[00:04:50] *** Mack has quit IRC
[00:05:03] <cybereal> that's wrong
[00:05:13] <cybereal> wrong wrong wrongity wrong
[00:05:32] <cybereal> you should only change it when the class is no longer compatible with previous potentially serialized versions
[00:05:38] <redrebel> ah, that explains why all my serializeable objects that that
[00:05:52] <cybereal> it's a way for you to override the default determination of serializable compatibility
[00:06:12] <redrebel> i've never changed it's value
[00:06:34] <cybereal> so if you added an optional field that could acceptably be null, you don't need to change the UID, if you do, it'll break compatibility with older versions unnecessarily you see...
[00:07:01] <redrebel> i always thought it had something to do with my version control
[00:07:11] <cybereal> heh no
[00:07:28] <whaley> redrebel: try removing it... you'll get a compiler warning
[00:07:45] <cybereal> redrebel: serialization is a really sort of... delicate thing, this is the way you can take control over compatibility between changes is all
[00:07:55] <cybereal> whaley: I've never seen the compiler warn about it
[00:07:56] <cybereal> just IDE's
[00:08:02] <whaley> redrebel: it is good practice to include it in your Serializable classes, for reasons already stated
[00:08:12] <whaley> cybereal: orly?  dumb me, then.
[00:08:29] <cybereal> I wouldn't jump to that conclusion
[00:08:35] <cybereal> maybe it shows up with the lint mode on?
[00:08:38] * cybereal doesn't compile that way
[00:08:47] *** sombriks has quit IRC
[00:09:06] <sproingie> eclipse whines about it by default
[00:09:24] <cybereal> yes it does, and it's the first thing I disable because I don't care
[00:09:32] <cybereal> I work on this aged codebase that predates the usage of that field
[00:09:45] <cybereal> and I'm sure as hell not going to update 300 classes with UID's just to salve a whining IDE :) hehe
[00:09:45] <sproingie> i was always told 1L was a magic default, but no, it uses that compatibility algorithm with any UID
[00:10:15] <cybereal> sproingie: the closest thing to a magic value is not having the field at all
[00:10:56] *** slango has joined ##java
[00:11:09] <sproingie> seems the only reason to use it is to explicitly make a new revision NOT compatible if you want it that way

[00:22:18] <Ven]n> and since I have my JSlider move every 200 millisecond.. it keeps changing setMediaTime over and over so I cant play the movie clip.

[00:25:37] <cybereal> sure but that's a totally different vector
[00:25:46] <cybereal> you shouldn't use the slider as a model

[00:26:15] <Ven]n> uhh

[00:55:02] <_val_> Hello there, I'm trying to generate some ints and usint an abstract methode which is defined in the class Interface. I'm not getting output. The code does compile. what could be wrong? This is what I've now http://fpaste.org/paste/3531
[00:56:52] <aceofspades19> _val_: you need to call getLight in the main method
[00:56:53] <ernimril> _val_: "for (int i=0; i<1; i++)" ?
[00:57:02] <wyvern> http://www.lowagie.com/iText/ [erja[s
[00:57:08] <wyvern> whoa, that was totally not the home row ;)
[00:57:27] *** fez has joined ##java
[00:57:27] <wyvern> *perhaps
[00:57:27] <_val_> aceofspades19: where to call it? I'm novivce to interface classes
[00:57:45] <aceofspades19> _val_: call getLight in main()
[00:57:47] <_val_> ernimril: it has to generate only once a random number @_@
[00:58:10] <aceofspades19> _val_: so why is it in a loop?
[00:58:10] <ernimril> _val_: why a for loop for that? kind of silly
[00:58:37] <_val_> ernimril: for example.. if I want to generate more ints.. I just could modify the loop
[00:58:44] <Mkop2> _val_: did you write that code yourself?
[00:58:53] <_val_> e.g  for(int i=1; i<10; ++i)..
[00:58:57] <Mkop2> my guess is that you just modified it and don't really understand all of what it's doing
[00:59:18] <ernimril> _val_: why add loops that you do not need? _when_ you need to randomize many time you add the loops you need
[00:59:22] <_val_> Mkop2: ofcaurse I wrote it.. it isn't that much code thou
[00:59:37] <aceofspades19> _val_: wouldn't you just loop through it in main()?
[01:00:08] *** fez has quit IRC
[01:00:08] <aceofspades19> like for(int i=0;i<SOME_NUMBER;i++) x = getLight;?
[01:00:12] <_val_> let me just modify.. the loop.. but I don't think it's the loop. It's not returning anything
[01:00:13] <Mkop2> _val_: do you understand what everything's doing?
[01:00:33] <Mkop2> before you get into interfaces, make sure you understand classes and methods
[01:01:14] <Mkop2> also, getLight() should be static the way you're using it
[01:02:49] <_val_> Allright I modified the loop. http://fpaste.org/paste/3535
[01:03:22] <_val_> so.. now the loop is ok.. it still isn't doing anything. I'm trying to understand the abstract methode in teh interface
[01:03:23] <Mkop2> _val_: you still are not ever calling getLight()
[01:03:54] <Mkop2> I think you are getting ahead of yourself with Interfaces when you don't understand methods
[01:04:05] *** b3nn3tt has joined ##java

[01:09:27] <Mkop2> 4 years of dabbling here and there a few hours a month, max
[01:09:34] <_val_> Mkop2: great that works.. but without implementing the interface .
[01:09:54] <Mkop2> _val_: do you understand the code?
[01:10:04] <bendermo> mkop:you enjoyed tv more to?
[01:10:18] <_val_> Mkop2: ofcaurse I do. but I don't know how to call the methode from the Interface class
[01:10:25] <Mkop2> you should be able to look at every line of the program and tell me what each individual line does
[01:10:34] <Mkop2> it's no different when it's an interface
[01:10:47] <Mkop2> an interface is simply a framework that requires a particular class to have a particular method
[01:11:17] <Mkop2> bendermo: no, I've just been doing other stuff. I'm not even a computer science major
[01:11:23] <_val_> All right.. System.out.println() prints just plaintext.  We are making an instance of Random by using new Random()  to generate random integers.
[01:11:45] <Mkop2> on line 8, what does each word mean?
[01:11:47] <_val_> then we use a preincrement in the loop to get 10 times the value of integers
[01:12:38] <_val_> we just define the method to be static
[01:12:53] <Mkop2> btw, I like that you explained the program from inside out. that's a much smarter way to think of it than linearly.
[01:13:10] <Mkop2> you know what static means? I bring this up because you didn't include it earlier
[01:13:21] <_val_> yes I do.
[01:13:29] <Mkop2> tell me
[01:13:41] <_val_> in java there are instance and static methodes
[01:13:57] <_val_> static methodes can't use any instance variables
[01:14:10] *** ankylose has quit IRC
[01:14:31] <_val_> Mkop2: I just can't find the link between Interfaces and the class.. it's purpose etc..
[01:14:36] <Mkop2> what would you need to do before you could call an instance method?
[01:14:54] <Mkop2> you would need to create a new Dummy() and then call theDummy.getLight()
[01:15:23] <_val_> true.. I did it inside the main methode.. but it gave me errors. How about the interface class?
[01:15:51] <_val_> I defined an abstract methode there.  Does interface class need mor methodes in this case?
[01:16:00] *** dmlloyd_ has joined ##java
[01:16:02] <Mkop2> in this case, no
[01:16:06] *** _some0ne has joined ##java
[01:16:24] <Mkop2> what is an interface in real life?
[01:16:37] <Mkop2> an interface is a standard way of interacting with something
[01:17:03] *** zmanning has joined ##java
[01:17:13] <Mkop2> it's a series of methods that every object that implements it must have
[01:17:40] <_val_> but I read on a pdf  which sais.. interface can ONLY have abstract methodes
[01:17:57] *** teralaser has quit IRC
[01:17:58] <Mkop2> that's true
[01:18:13] <Ven]n> These two are giving me problems. The playMovie() is changing the frameSlider while movie is running, but I want to be able to change the current time myself by dragging the slider. The problem is that by changing automatically in playMovie() it notices that in stateChanged() as well. And by that interferes so the video clip is lagging: http://rafb.net/p/6xe9DZ78.html
[01:18:23] <Mkop2> which makes sense if you understand what an interface is
[01:18:45] <Mkop2> usually interfaces are called ___Able
[01:19:37] *** cyth has quit IRC
[01:19:48] <_val_> Mkop2: when I say  public class Dummy extends LightSensore.. which in this case is my interface class.. it goes to  "public static void getLight() and says. The static methode cannot hide the instance methode from LightSensor
[01:19:49] <Mkop2> like Interface Printable means that you can print the object
[01:20:25] <_val_> s/extends/implements
[01:20:31] <Mkop2> which means that it *must* have a method print()
[01:20:39] <bendermo> mkop:Java is so object oriented that I consider c++ easier
[01:20:53] <Mkop2> Java is so object oriented that I consider java easier
[01:20:58] <Mkop2> OOP is awesome
[01:21:15] <Mkop2> _val_: that's the code from the compiler?
[01:21:22] <Mkop2> s/code/output/
[01:21:39] <_val_> Mkop2: no I meant   public class Dummy implements LightSensor
[01:21:56] *** magcius has quit IRC
[01:21:59] <_val_> then I get that error at  public static void getLight()
[01:22:19] *** dmlloyd has quit IRC
[01:22:20] <Mkop2> you need to change the method header up top to match what I made it down below

[01:22:23] *** dmlloyd_ is now known as dmlloyd
[01:22:29] <Mkop2> instead of int getLight() make it static void getLight()
[01:23:08] <_val_> Mkop2: but the abstract methode in interface class LightSensor  is defined as  abstract int getLight();
[01:23:19] <Mkop2> so change it
[01:23:32] *** peerce has joined ##java
[01:23:38] *** TorfusPmorphus has left ##java

[01:23:52] <Mkop2> that might work
[01:24:10] <peerce> I'm running into an odd syntax I don't quite understand...   like, a declaration in a class template looks like:    public List<Contact> read();
[01:24:10] <_val_> So you are saying   abstract int getLight() wont work? @_@

[01:26:32] <Sou|cutter> So I'm having connection pool starvation issues, and I'm thinking about writing a prepared statement wrapper which will keep a handle to the connection, and close the connection immediately after ps.close() is called (for non-transactional queries only). Can anybody think of any gotchas there? (is this a bad idea for some reason that I haven't thought of)?
[01:26:46] <Mkop2> but there's still the question of does it return an int or not
[01:26:48] *** drip has quit IRC
[01:26:53] <_val_> Mkop2: indeed.. I made it  public void getLight();
[01:27:07] <Sou|cutter> because currently it's all but guaranteed that conn.close() isn't called immediately after ps.close() in most cases
[01:27:20] <_val_> Mkop2: it does return now .  But my methode is now void and not int
[01:27:21] <_val_> :<
[01:27:24] <dmlloyd> Sou|cutter: assuming you're using JDBC directly, yeah you should close the connection as soon as you can I would think

[01:28:26] <Sou|cutter> dmlloyd: hopefully the overhead of doing jndi lookups for the pool is less than the contention/starvation problems... or that's my thinking

[01:42:22] *** Inhuman has quit IRC
[01:42:48] <_val_> this won't coompile cause there is no  return statement in the methode. But I want to be it int and NOT void.
[01:43:34] <_val_> It's nothing wrong with void.. but it's just getting to know the other way of using it.
[01:43:43] <Sou|cutter> ok...
[01:43:51] *** indeterminatus has quit IRC
[01:44:22] <Sou|cutter> _val_: So the problem is that you don't return an int from a method whose signature says you need to return an int
[01:45:13] <Sou|cutter> I don't know why you're looping 10x to get a random intensity -- why not eliminate the loop and just have getLight() return the first random intensity value that it produces?
[01:45:32] <Sou|cutter> you can loop around your method call to getLight() to get multiple random intensities if you want
[01:45:53] <_val_> Sou|cutter: yes I wouldn't mind but do I use   return getLight();
[01:45:54] <_val_> ?
[01:46:16] <Sou|cutter> no, that would be infinitely recursive
[01:46:17] <_val_> I put the loop just to produce more text.. nothing special on that

[01:50:57] *** convivial has quit IRC
[01:51:28] <Sou|cutter> I have some problems with that code, but for a beginner I didn't want to get into deeper issues than what you're asking about (you have plenty of time to figure out better ways to do things once you have more-solid fundamentals)
[01:51:42] <Sou|cutter> _val_: Glad to help.
[01:52:04] <_val_> Writing a class itself with methodes and other stuff isn't that hard.. but I just lost the concept of using the  Interface class
[01:52:49] <Sou|cutter> It should become more natural to you as you learn more
[01:53:06] <Sou|cutter> sounds like you're on the right track :)
[01:53:48] <_val_> I hope so. As many says, the beginning is always taugh, but I'm not giving it up
[01:54:50] <_val_> And I'm focusing a lot on theorie of Java, less the implementation of it. But if you can't implement it.. what's the need of theory?

[03:17:17] <javabot> http://i38.tinypic.com/25aopzn.jpg
[03:17:35] <oxi> I believe in java there's a way to make a class directly accessible by it's classpath name without having to instanciate it.
[03:17:40] <oxi> I'm not sure thought.
[03:17:44] <AMcBain> _some0ne: with a little imagination, it's not hard to do ... the shuntyard algorithm would work nicely here, but you instead of adding the operations to the end of the strring when it says, you put them at the beginning.
[03:17:49] <eidolon> ~~oxi static
[03:17:49] <javabot> oxi, static is a keyword which indicates that a member is scoped to a class rather than an object instance.  Members of interfaces (except methods) are always static.  Nested interfaces and enums are always static.  See http://tinyurl.com/3q7oc and http://tinyurl.com/34vr3u for more information.
[03:17:53] <oxi> Does anyone remeber the term.?
[03:18:00] *** waz is now known as Guest3804
[03:18:08] <_some0ne> that's basically what i'm working trying to do
[03:18:18] <oxi> so, the thing is that you can make a whole class static, right?
[03:18:32] <AMcBain> well, the S-Y algorithm isn't hard ... I did it in a short amount of time.
[03:18:41] <oxi> I thought there was a different term.

[03:19:05] <_some0ne> well i'm sure i'll figure it out

[03:21:21] <kaos01> yes, i liek a global setting ,idealy some global config files
[03:21:27] <eidolon> try -Xmx128m
[03:21:29] <AMcBain> _some0ne: I redefined their idea of a "token" to be 1 character and processed things that way, as operators are 1 character in length, and anything else was either a space (ignore), a A-Z_a-z character (function name), or a number. if I received numbers or characters, I kept looping until I hit another space or operator. (this does require you to append a space to the end of the string to make sure you get everything though :P)

[04:16:38] <javabot> aleksei, aolbonics is using unnecessary abbreviations such as 'u', 'r', 'ur', 'thx', etc. Using this language depicts you as an imbecile in the eyes of the helpful regulars in this channel, and is generally not tolerated.  If you want intelligent answers, the least you can do is speak intelligently.  Additionally arguing about this rule will get you nowhere except banned.  Have a nice day!
[04:16:49] <r0bby> it's YOU not 'u'
[04:17:03] <brady_k> r0bby: um... reread it.  I said "you"
[04:17:11] <aleksei> oh please forgive mee
[04:17:23] <brady_k> oh you're speaking to aleksei, sorry
[04:17:30] <metsfan> well i'm not an expert, but i do have this program mostly done, i tried using a Runnable, and tried SwingMethods.invokeLater neither solved my problem

[04:17:53] *** brady_k has left ##java
[04:17:53] <metsfan> sorry =)
[04:17:58] <aleksei> anyway, metsfan, the problem is, i'd bet, you are not updating the JProgressBar in the EDT
[04:18:04] <r0bby> that fucker
[04:18:13] * AMcBain wrote a cool "progress-bar" once :P
[04:18:33] <The_Birdman> so how cooler is AMcBain now?

[04:23:11] <metsfan> aleksei, if i am putting the code to update eth progress bar in a runnable which i run with invokeLater, doesn't that mean i'm doing the update in the EDT?
[04:23:42] <metsfan> am i misunderstanding how the EDT works?
[04:23:57] <AMcBain> invokeLater should run on the EDT, yes.
[04:23:58] <aleksei> metsfan: yes, then there must be something else blocking the EDT
[04:24:11] <AMcBain> you shouldn't be doing processing on the EDT, just updating.
[04:24:13] <aleksei> why dont you pastebin the code
[04:24:19] <metsfan> will do

[04:24:40] *** viperhr has quit IRC
[04:25:11] <aleksei> AMcBain: so what are the features of your ProgressBar?
[04:25:32] <AMcBain> similar to the real one, you can set a percentage or let it infinitely "loop"
[04:25:56] <AMcBain> doesn't have a real "interface" from a Swing component other than the JPanel it was probably made on.
[04:26:16] <AMcBain> I think you can even set som text, but it's rather static ... I didn't try hard there.
[04:26:58] <AMcBain> iirc, the code was rather simple, so it's easily hackable for different colors, etc.
[04:27:06] <AMcBain> you may have been able to set the speed it moved at.
[04:27:33] <aleksei> I see
[04:28:01] <metsfan> http://pastebin.com/m2921bcd
[04:28:15] <metsfan> i included only the code relevent to the progress bar
[04:28:20] <AMcBain> I did it once to see if I could make it from a Canvas and JS script I created once. and I'd much rather something like it or the original JProgressBar make it into nimbus ... as the progressbar for nimbus (last I checked) look fugly.

[04:29:23] <AMcBain> aleksei: you might have an easier time if you just downloaded it and opened it up .. I think the source is in it.
[04:30:18] <metsfan> i mean the code is pretty simple i don't see why it wouldn't work
[04:30:40] <aleksei> I don't think repaint is needed
[04:30:47] <metsfan> same result without it
[04:31:06] <AMcBain> you might try moving the setValue and stuff about that before the invokeLater, and just call repaint inside the invokeLater.

[04:33:12] <aleksei> maybe it's so fast you dont see it moving?
[04:33:42] <aleksei> it just increases the PBar value but does nothing...

[04:34:06] <SherlawkDragon> ^MySQL

[04:37:23] <metsfan> indeed that would make sense
[04:37:33] <AMcBain> SherlawkDragon: try JDBC
[04:37:42] <metsfan> so the operations i am doing would have to be done outside the action listener?

[04:38:07] <ebering> \ ZeroToThree OctalDigit OctalDigit
[04:38:26] <AMcBain> but that thread has to call invokeLater though ... otherwise you're accessing the EDT on a different thread
[04:38:28] <ebering> but in the following paragraph states that \300 is invalid.
[04:38:29] <aleksei> and in that thread use EventQueue.invokeLater if you are touching the UI

[05:09:40] <thefalling> In java, if you call a thread in an application, and that application is closed without closing the thread first, does that thread terminate?

[05:10:38] <dmlloyd> it terminates when all non-daemon threads terminate
[05:10:49] <dmlloyd> killing an app with exit() kills all threads immediately
[05:11:21] <dmlloyd> in other words, no threads outlive the process
[05:11:39] *** mistik1_ has joined ##java

[05:12:26] <dmlloyd> only if the thread is a daemon thread
[05:12:37] <dmlloyd> your main method is also running in a thread you see.
[05:13:04] <dmlloyd> once your main method starts up a thread, you now have two threads.  The app doesn't terminate until both threads do, or until you call .exit()

[06:25:05] <pstickne> AMcBain:  languages with easily matchable discriminated unions really excel here :)
[06:25:30] *** nixblicker has left ##java
[06:25:33] <AMcBain> yeah, my switch was an initial thing that seemed a great idea until I realized I needed to do each alpah character.
[06:25:42] <AMcBain> alpha*
[06:25:51] <AMcBain> but I never converted it ... I just typed away
[06:26:59] <AMcBain> _some0ne: as I said, make those lines (except for the first one) into something that puts the stuff at the beginning of the LinkedList instead of the end (the push() that it currently does) and you'll have your prefix
[06:27:34] <AMcBain> the only ones you want to stay as a "push" are the numbers themselves, I assume? or is prefix a reverse of postfix?
[06:27:37] *** casmo has joined ##java
[06:27:41] <AMcBain> (in which case the numbers flip too)
[06:27:56] <_some0ne> prefix is conceptually a revers of postfix, iirc
[06:28:11] <AMcBain> ah yes, then you want to convert line 298 too
[06:28:35] <AMcBain> you can change my LinkedStacks to use the LinkedList directly and do addFirst instead.
[06:28:54] <AMcBain> the output will still be a "pop" to turn it back into a string, though.
[06:29:30] <AMcBain> I'd at least try it and see how it works.
[06:29:39] <_some0ne> well thanks for all your help. I'll keep your code in mind as i work on mine. i g2g now..
[06:29:39] <AMcBain> you can drop half that code by removing the evaluator
[06:29:48] *** jkriesten has joined ##java
[06:29:57] *** _some0ne has quit IRC
[06:30:22] <AMcBain> Yeah ... assuming  you ignore that the +3 ... -3 etc, don't parse right, that code works rather nicely :)
[06:30:39] <AMcBain> (the regex works sorta well, but it fails on -(3 ... ) type stuff)

[07:05:36] <Wicked> tieTYT, hmm ok let me see if i can get it to print it out.
[07:05:39] <reverend> it's an API exception

[07:15:07] <AMcBain> tieTYT: we just need to hook up a brain scanner that changes the comments as necessary :P
[07:15:35] <tieTYT> or turn your comments into methods with descriptive names
[07:16:11] <AMcBain> that's a nice approach too :)
[07:16:58] <AMcBain> I put comments where necessary (enough that someone could determine what I mean) but descriptive names on variables classes, methods, etc. helps imensly, even if it's just yourself coming back half a year later.
[07:17:18] <tieTYT> yes it's more helpful than comments
[07:17:24] *** CrypticSquared has quit IRC
[07:17:34] <tieTYT> and it's harder to lie

[07:18:08] <cybereal> I only write comments as reminders to myself
[07:18:15] <cybereal> javadoc is for explanation
[07:18:23] *** Riov has quit IRC
[07:18:42] <tieTYT> i consider a javadoc to be a comment
[07:18:46] <AMcBain> yeah, Javadoc is the forward facing "comments" for people using it.
[07:18:57] <tieTYT> i mean my own javadoc
[07:19:01] <tieTYT> i assume that's what you mean too
[07:19:04] <cybereal> javadoc might go IN a comment but it's not a comment
[07:19:15] <cybereal> it's documentation, that's different
[07:19:19] <cybereal> it shouldn't be changing often
[07:19:40] <tieTYT> it should never change
[07:19:43] <tieTYT> doesn't mean it won't change all the time
[07:19:54] <cybereal> no, it should change
[07:19:58] <cybereal> just not very frequently
[07:20:11] <tieTYT> ideally it should never change
[07:20:19] <tieTYT> just like ideally comments will never become out of date
[07:20:56] <tieTYT> you can put javadoc on a private method if you want
[07:20:58] <tieTYT> or even a field
[07:21:09] <tieTYT> that will probably change
[07:21:28] <tieTYT> i'm rambling, but I consider comments and javadoc a necessary evil
[07:21:40] <cybereal> I totally disagree with all of that

[07:51:23] <AMcBain> tieTYT: I almost always tell it to use the System L&F ... which makes it look relatively nice on everything but Linux
[07:51:24] <tieTYT> cause you don't have to create so many panels inside panels to get things to look like you want
[07:51:43] <tieTYT> AMcBain: you're a fool of a took if you think that looks relatively good on windows

[07:52:36] <AMcBain> The default blue is shit, and so is "classic" though
[07:52:48] <tieTYT> well that's kinda irrelevant.  EIther way java's defaults on windows look ugly
[07:53:24] <AMcBain> Setting it to use the System L&F isn't a default ... you have to explicitly do it.

[08:04:59] <cybereal> seems fine to me, but still, overall it's much nicer than usual java cruft
[08:05:35] <Shirik> Hello all, can someone explain this discrepancy to me? Why is line 3 legal but not line 6?
[08:05:37] <Shirik> http://wowi.pastey.net/108229
[08:05:39] <AMcBain> it all looks good, but for that one mode, for that one object, I see shit down a tube :P
[08:05:58] <AMcBain> (and the orange color just stands out)
[08:06:40] <cybereal> eh
[08:06:59] <cybereal> Shirik: your error in your comment doesn't even make sense, what java compiler are you using?
[08:07:17] <Shirik> sec
[08:08:07] <cybereal> oh wait I see that's in a ... yeah didn't notice that was an anonymous inner class there
[08:08:16] <cybereal> there's absolutely no point in making a static member on an anonymous class
[08:08:27] <Shirik> adding -version says javac 1.6.0_11
[08:08:38] <Shirik> it's the Sun JDK
[08:08:51] <cybereal> Shirik: what happens when you remove that line entirely?
[08:09:08] <Shirik> cybereal: It compiles fine
[08:09:17] <Shirik> Now I can accept that line 6 is an error; it doesn't make sense
[08:09:20] <Shirik> but why is line 3 not an error
[08:09:27] <cybereal> it compiles fine?
[08:09:37] <Shirik> yup
[08:09:39] <cybereal> does it compile fine or not?
[08:09:42] <cybereal> then what's the problem?
[08:09:53] <Shirik> the fact that there's a discrepancy between line 3 and 6
[08:10:04] <Shirik> If static members are not legal, then why is line 3 not an error
[08:10:05] <cybereal> you're being obtuse
[08:10:06] *** woogley has joined ##java
[08:10:16] <cybereal> or just a moron
[08:10:18] <Shirik> No, I'm being curious. I already have a solution, that's not what I'm asking for.
[08:10:24] *** foo-nix has quit IRC
[08:10:25] <cybereal> does line 6 compile or not?
[08:10:28] <Shirik> I'm asking for insight into why this would be legal.
[08:10:34] <Shirik> You said remove it; I remove it and it's fine
[08:10:49] <cybereal> Shirik: ok, so the big difference here is that your line 6 is invoking a method
[08:11:02] <cybereal> to make a final assignment to a static member
[08:11:21] <cybereal> Shirik: whereas the first one is just inlining a literal
[08:11:32] <Shirik> ok, that makes sense
[08:11:34] <cybereal> very different operations

[08:12:32] <Shirik> personally I think the error message is a little ambiguous, but that's not really important :)
[08:12:34] <Shirik> Thanks
[08:12:41] <cybereal> still a better question is why you'd have a static final variable on an anonymous class
[08:13:11] <Shirik> I just don't want to keep compiling the pattern. I was hoping that making it static would do it just once and keep it
[08:13:18] <Shirik> I just moved it to the enclosing class, not a big deal
[08:13:38] <selckin> or don't make it an anonymous class
[08:13:39] <cybereal> anonymous classes are kinda hacky
[08:14:15] <tieTYT> i think when java gets lambdas
[08:14:22] <tieTYT> it's going to make java syntax look like C++
[08:14:36] <cybereal> java syntax already looks like C++, always has, it was designed to
[08:15:05] <tieTYT> it's not as bad
[08:15:12] <tieTYT> it doesn't have * and ::
[08:15:15] <tieTYT> and : all over the place
[08:15:28] <tieTYT> nor >> and <<
[08:15:32] <tieTYT> oh wait, it does have one of those
[08:15:39] <tieTYT> but it's not very common
[08:15:41] <AMcBain> ::--
[08:15:48] <tieTYT> 8===D
[08:15:57] <AMcBain> er, I was going for :: minus minus ...
[08:16:02] <AMcBain> (pervert)
[08:16:08] <pfn> how are lambdas going to make java look like c++
[08:16:22] <tieTYT> i overload 8==D to be my string concatenation operator
[08:16:32] <pfn> I guess if they're bgga, you've got => but that doesn't look like c++
[08:16:45] <tieTYT> pfn: literally, they won't
[08:16:56] <tieTYT> pfn: but i think if they're type safe it's going to be kinda messy to look at

[08:34:30] *** riotz has quit IRC
[08:34:53] <jgoo> hola amigos - I have some dope files written on an ancient mac, and I have no idea about their encoding. I've dealt with this before in Java, but am now searching for some 'encoding brute force' framework that takes a file, and displays snippets of it after trying different encoding / conversions
[08:35:24] <jgoo> I've seen this problem before, but because it is a mac file originally, I am stumped... maybe over-thinking it, but the bext I can get out of it is ÁÔÚ‡ÔÌÂÓ
[08:35:51] <jgoo> Which means it is some native format being decoded as utf8?
[08:36:30] <AMcBain> most likely
[08:36:39] *** tomvolek has joined ##java
[08:36:42] <cybereal> jgoo: or it's not character data at all...
[08:37:48] <jgoo> No, it is character data, I am sure of that
[08:38:02] <jgoo> I have people say that the company that archived the files from these old macs showed the files on another mac
[08:38:31] <cybereal> how is that relevant?
[08:38:50] <jgoo> Oh, I see what you are saying - no, they are character data
[08:38:50] <cybereal> hey jgoo, if it's from a PPC mac the byte order is probably wrong
[08:38:53] <jgoo> I can tell they are not binary
[08:38:59] <cybereal> maybe it's utf-16 with swapped bom
[08:39:00] <jgoo> on account of formatting and linebreaks of the document
[08:39:02] <cybereal> :)
[08:39:05] <cybereal> (though not likely)
[08:39:25] <cybereal> can you open it in vim?
[08:39:26] <jgoo> Yeah, shame, best editor for testing is notepad++, a gnu app, NOT AVAILABLE ON LINUX
[08:39:30] <jgoo> I'll try emacs
[08:39:54] <jgoo> wait, I don't think that supports utf8 even (or is that only via ssh) I forget
[08:40:11] <jgoo> Can you swap a BOM? I think it is either there or not...
[08:40:21] <cybereal> you can swap byte order

[08:41:09] <jgoo> Yeah, the problem is, I can almost read some badly encoded files, because you are used to how they look... this one does open the way I usually achieve it...

[08:46:24] <mitch0> try UCS2-BE and UCS2-LE
[08:46:30] <omegaman> is there a good framework out there to hack up web surveys / questionairees?
[08:46:42] <AMcBain> jgoo: yes, the bot in this channel responds to ~
[08:46:51] <jgoo> ~google cuil
[08:46:51] <javabot> http://letmegooglethatforyou.com/?q=cuil
[08:46:58] <jgoo> that is great
[08:47:03] <jgoo> ~cuil cuil
[08:47:03] <javabot> jgoo, I have no idea what cuil cuil is.
[08:47:21] <Logi> ~cuil
[08:47:21] <javabot> Logi, I have no idea what cuil is.
[08:47:48] <jgoo> This looks good mitch, thanks. I like the docs about the circular dependency it has
[08:49:28] <mitch0> jgoo: what circular dpes?
[08:49:39] <mitch0> s/dpes/deps/
[08:49:43] <jgoo> "first libiconv, then gettext, then libiconv again,"
[08:50:02] <jgoo> then it says, or the other way around... probably something needs to be pulled out into a libtextutil or something
[08:50:45] <mitch0> erm, you lost me there, but nevermind. just try it out ;)
[08:50:50] <jgoo> Will do =).
[08:51:05] <jgoo> So, the other day I was thinking, ffs, there isn't any decent font showcase app out there.
[08:51:07] *** agnul has joined ##java
[08:51:42] <mitch0> I think I saw one once
[08:51:56] <mitch0> xfontselector? something like that
[08:52:14] <jgoo> I went online and download all the crap windows font previews (into a clean vm... they have so much crap) and they all sucked, and none of them supported utf8. In less time than it took to download all of those, I hacked up a quick demo that pulls all the installed fonts, and lets you preview your text in multiple fonts, paging.
[08:52:51] *** ridoo has joined ##java
[08:52:52] <cybereal> font book on mac is pretty nice for exploring fonts...
[08:52:55] <jgoo> I wrote one in Java... I want to optimize is... and add the ability to have large font sizes, kerning previews, overlay comparisons, and perhaps a 'find this font' feature.
[08:53:02] <jgoo> mac has everything, damn it.
[08:53:27] <jgoo> this little file encoding problem is the perfect excuse to buy the new macbook.
[08:53:52] <cybereal> heh well if it's from some old-ass mac app there's no special reason to believe a new mac is going to display the file any easier
[08:54:03] <cybereal> though I could try it for you if you wanted ;)
[08:54:25] <pfn> download the most recent 'file' command and 'magic' and use it
[08:54:34] <jgoo> =)) yeah, problem is, some of the files are confidential... and because I can't read them, I don't know which ones :((
[08:54:58] <mitch0> hehe
[08:55:17] <jgoo> pfn, it is a plain text file, can magic detect encodings? (non-latin characters) I thought it just detected filetypes
[08:55:38] <pfn> tias

[10:33:59] *** Kjartan has joined ##java
[10:34:05] <umz> like I have to either cast it to ClientImpl or change the type to ClientImpl

[10:36:04] <dangertools> umz: i guess not, the compiler doesn't lie.
[10:36:18] <Infinito> isr`, complex guis are usually very specific... all you can do is really tutorials about the separate components..
[10:36:22] <umz> well dangertools lemme paste you the code at pastebin

[10:36:56] <goki-_-> goki-_-: If you just want an answer, I would say use the built in java logging.
[10:37:05] <goki-_-> Dunno why I'm talking to myself

[11:27:08] *** UT2K3 has quit IRC
[11:27:47] <Infinito> you need to declare a Constructor method Kjartan.

[11:34:09] <dangertools> what?
[11:34:26] <Kjartan> Using the extended class?

[11:42:40] <fanti> hello! i'm looking for an example on dynamic class REloading. when a class that is already present has changed to make the changes visible for new instances of that class
[11:43:28] <fanti> trying already to use the ClassLoader.loadClass method but that had no effect. it used always the old version of the class

[12:10:50] <Jubei> guys what is the best way to check for this  ... ex.   50<x<100 , it cant be done with a switch statement right? do I have to do if (x>50 && x<100) ?
[12:12:24] <mitch0> that exact example could be done with a switch (but would be fugly :)
[12:12:39] <mitch0> the (x > 50 && x < 100) is the way to go
[12:12:49] <Jubei> thank you mitch0 .
[12:12:53] <mitch0> although I prefer to write (50 < x && x < 100)
[12:13:02] <Jubei> oh yea that looks nicer ^^

[12:50:44] <mazzachre> bdbdbd: Well it is caught internally it sounds like... I also find it strange that java complains about that I try to catch something that is never thrown inside the try{}... It should warn me... not err out :/
[12:50:57] <sanity> anyone aware if there is a concurrent LinkedHashMap implementation (or something else I can use to create a fine-grained concurrent LRUMap)?
[12:51:23] *** mistik1 has joined ##java
[12:52:10] <jottinger> sanity: there's a concurrenthashmap, which you can use to do that (I did it, for example, last week)
[12:52:18] <jottinger> you can also se ehcache or oscache
[12:52:55] <sanity> jottinger: how do you use a concurrenthashmap to create an efficient LRUMap?
[12:53:01] <jottinger> s/se/use/
[12:53:27] <jottinger> sanity: it's a map... the actual internal storage/lookup shouldn't matter
[12:53:38] <jottinger> linkedhashmap is much harder to sync
[12:53:44] <jottinger> linkedmap, sorry
[12:53:50] <jottinger> I JUST woke up :/
[12:54:00] <sanity> jottinger: you have to maintain an ordering of the elements in the map, that is why you need a *Linked*HashMap
[12:54:03] *** Resistance has quit IRC
[12:54:16] *** morkar- has joined ##java
[12:54:35] <jottinger> but it's a map! Why would linked be necessary? Ah, I see what you're doing...
[12:54:43] <jottinger> sanity: that's fair, but in my experience, YAGNI
[12:55:01] <jottinger> sanity: removing expired entries is pretty easy regardless, no need for ordering
[12:55:01] <sanity> jottinger: why not?
[12:55:13] <sanity> jottinger: without the ordering it isn't LRU
[12:56:25] <jottinger> sanity: I use an access time and an expiry
[12:56:33] <jottinger> it depends on what you need and your environment
[12:56:42] <sanity> jottinger: how do you efficiently find the elements that are about to expire?
[12:56:55] *** CrypticS_ has joined ##java

[12:57:39] <sanity> jottinger: ah, I see - but unfortunately I need it to prevent memory from filling up
[12:57:41] <jottinger> if I'm really worried about only having X entries, I'd store a List along with the map with the access order

[13:00:09] <sanity> jottinger: concurrency isn't required, but it means my app occasionally freezes if I need to traverse the map - which is not good

[13:07:13] <enterneo> jottinger: up until now I was using POJO bean to in <html:form> and then mapping POJO bean to EJB from within Action class, but this way i get 2 beans with exactly same properties (seems like an unnatural way of doing it)

[13:13:56] <dangertools> mitch0: all Exceptions are Throwables but not all Throwables are Exceptions

[13:14:02] <dangertools> mitch0: there's also java.lang.Error
[13:14:12] <dangertools> bdbdbd: one is a block, the other is an interface
[13:14:17] <jottinger> right, exceptions must be caught, errors don't care

[13:14:40] <bdbdbd> is it friday or is it saturday?
[13:14:48] <jottinger> depends on where you are

[14:16:46] <mr_daniel> I know in Java there is a speciel construct  Classname.class to create a object of type Class<Classname>
[14:17:18] <mr_daniel> I understand this. The Class 'Class' is used to get introspecion and reflection capabilites
[14:17:30] <mr_daniel> like determine the names of methods, parameter list, etc.
[14:17:37] <mr_daniel> but what I don't understand:
[14:18:07] *** ScottG489 has quit IRC
[14:18:14] <mr_daniel> in which situation a programmer uses 'Classname.class'? when the use of 'Classname.class' is absolutely necessary?
[14:18:36] <mr_daniel> is there maybe a special type of programming paradigm, which relays on the use of 'Classname.class'?
[14:19:05] *** geaaru has quit IRC
[14:19:23] <mr_daniel> ...a speciel paradigm which depneds on 'Classname.class'...?
[14:20:09] <mr_daniel> the point is: I have NEVER used such a statemtent (Classname.clas) in any of my so far written java programs
[14:20:18] <dangertools> ~reflection
[14:20:18] <javabot> dangertools, reflection is http://java.sun.com/tutorial/reflect
[14:20:25] <mr_daniel> I just want examples when it makes sense to use a such feature
[14:20:36] <mitch0> Logger.getLogger(MyClass.class)
[14:21:22] <mr_daniel> 'Logger.getLogger(MyClass.class)'? But why not use 'Logger logger = new Logger(...)' ?
[14:21:40] <mr_daniel> for me 'new Loger(...)' and 'getLogger(...)' has the same effect
[14:21:43] <mr_daniel> and also the same benefit
[14:21:48] <mr_daniel> I dont see any difference
[14:22:12] <mitch0> erm, the first part was not important
[14:22:24] <mitch0> it could be new Logger(MyClass.class)

[15:48:29] <eidolon> ~final
[15:48:29] <javabot> eidolon, final is a Java keyword that denotes that its target cannot change.  A final field/variable cannot be assigned more than once, a final method cannot be overridden in a subclass, and a final class cannot be subclassed.

[17:59:42] <cheeser> ~~ Stef1 newbie ide
[17:59:43] <javabot> Newbies shouldn't start with IDEs.  It's important to learn the environment and fundamentals of a language before offloading those to an IDE.  Learn about packages and imports and classpaths.  Learn how to compile and use the JDK tools.  Get some basic grasp of the API layout.  Learn how to do things then switch to an IDE to do them faster.  See http://tinyurl.com/yvks48 and and http://tinyurl.com/2cpn6o for more info.

[19:04:45] *** zophy has quit IRC
[19:05:11] *** zophy has joined ##java
[19:05:22] <jbartels> do the javadocs indicate that there might be quirks to isFullScreenSupported() ?
[19:05:45] <tieTYT2> isn't that easy to check?
[19:05:52] *** javahorn has joined ##java

[19:06:14] <sidelil> jbartels, Im checking and it always returns that i cannot use the fullScreenMode
[19:06:42] <jbartels> what happens if you skip the check and just go straight to fullscreen mode?
[19:10:54] <pgib> Hello, we have a case where our application receives data from a 3rd party.  We need to verify the sender of the message.  So, the sender salts the payload with a pre-shared key, then send the MD5 of this with the payload.  Then we verify the message by recomposing the MD5 with the same preshared-key we have on our server
[19:11:10] <pgib> This works, but any suggestions on maybe a better digest algorithm to use?
[19:12:06] <pgib> and is there someway to do this with a private/public key pair?  I know it is slightly offtopic, but I figured there is a good deal of Java+Web experience here
[19:13:42] *** Riov has quit IRC
[19:14:35] <Sou|cutter> pgib: use SHA-256 instead of MD5
[19:15:19] <Sou|cutter> pgib: You could use TLS Authentication... a two-way ssl handshake
[19:15:29] <pgib> OK, any recommendation on privateKey size? I guess around 512 or so?
[19:15:39] <dmlloyd> SHA doesn't use a private key
[19:15:48] <Sou|cutter> it's just a hash
[19:15:49] <pgib> well,I mean for the salt
[19:15:53] <dmlloyd> unless you mean a shared secret ke to salt
[19:15:58] <dmlloyd> in which case, longer is better :)
[19:16:25] <dmlloyd> you might also want to look at MAC...

[19:17:18] <sidelil> jbartels, oh sorry i didnt see your message. I happens that it creates a maximised window (i.e. in the top left corner) as it's supposed to do when it cannot turn to full screen. I thought it was a problem on my linux machine, but it doesnt run full screen on windows either
[19:17:26] <dmlloyd> and signatures...

[19:18:07] <Sou|cutter> but they were spammy

[19:18:17] <pgib> sure. Ok thanks for the resources
[19:18:20] <jbartels> sidelil: OK so since it doesn't work you were using the isFullScreenSupported() to find out if it should work on that machine

[19:51:36] <jottinger> Java's just a VM with a set of languages that run on it.
[19:51:42] <ernimril> java was a lot smaller in the api when it appeared

[19:52:27] <gfather> and when i thought about what programming languages i should lean , java was the best option

[20:15:43] <AlanasAnikonis> yes, apt-get install eggdrop
[20:16:13] <cybereal> um I don't use politically motivated linux distributions
[20:16:36] <EdwardIII> debian is political?

[20:16:48] <cheeser> FOSS or nothing
[20:16:52] <EdwardIII> ah right
[20:16:53] <cybereal> EdwardIII: its sole reason for existence, actually
[20:17:04] <EdwardIII> ubuntu isn't so strict, is it? maybe he's apting from ubuntu!
[20:17:10] <cybereal> heh
[20:17:12] * EdwardIII is irsssing from ubuntu
[20:17:23] <AlanasAnikonis> well I am using ubuntu/kubuntu only...

[20:17:38] <cybereal> and I don't use fink
[20:17:40] <AlanasAnikonis> i didn't know i had politics in my computers :(
[20:17:55] <EdwardIII> i think apt is a fantastic bit of software and way ahead of the game when it was first popular
[20:17:58] <EdwardIII> haha

[20:22:39] <thepenguin37> hi. i have a question about threads. is the thread killed after complete its work in run method
[20:22:41] <thepenguin37> http://eugeneciurana.com/pastebin/pastebin.php?show=40278
[20:22:47] <pr3d4t0r> cybereal: So I had to learn the relationship between The Economist, FT, and Pearson, and how it plays.
[20:22:50] <svm_invictvs> pr3d4t0r: What is that/
[20:22:51] <coalado> guys... thx but I do not need any links to the URL.java docs
[20:22:54] <dmlloyd> coalado: URL is the way you download stuff via http, or at least, the simplest way
[20:22:57] <EdwardIII> cybereal: why is it any more fantastic than linux + gnome? plus i don't think that to the majority of users that linux is about the freedom of speech, more about the stuff for free
[20:22:58] <cybereal> thepenguin37: killed is the wrong word, the thread exits
[20:23:16] <pr3d4t0r> svm_invictvs: ?
[20:23:17] <thepenguin37> cybereal: ok.
[20:23:17] <EdwardIII> cybereal: i'm not trying to troll or be aggressive by the way, i'm just interested
[20:23:20] <coalado> dmlloyd:  I already wrote a download system
[20:23:26] <pr3d4t0r> svm_invictvs: What is what?
[20:23:26] <coalado> that uses multiple connections
[20:23:29] <dmlloyd> coalado: then... what's your question
[20:23:30] <cybereal> EdwardIII: it works, I have never once had to edit a configuration file to get X11 running again after an update fucked it up, for example
[20:23:35] <svm_invictvs> pr3d4t0r: Economicst COnferences
[20:23:41] <cybereal> EdwardIII: I can go to the store, buy BRAND NEW awesome hardware/devices and they are supported, etc.
[20:23:42] <EdwardIII> heh - to be fair i've never had that issue either
[20:23:43] <pr3d4t0r> svm_invictvs: Are you familiar with The Economist?
[20:23:44] <coalado> but my problem is the right buffersize
[20:23:48] <pr3d4t0r> svm_invictvs: The British magazine.
[20:23:54] <svm_invictvs> maazine?
[20:23:55] <svm_invictvs> *oh
[20:23:57] <cybereal> EdwardIII: just generally, it's the most UNIX for the least effort
[20:23:58] <svm_invictvs> Magazine
[20:23:58] <svm_invictvs> Yeah
[20:24:10] <coalado> i use a buffersize of about 200kb / connection
[20:24:24] <pr3d4t0r> svm_invictvs: The Economist has a division called The Economist Intelligence Unit that does D-, C-, VP- level conferences all over the US, on various topics.
[20:24:25] <thepenguin37> cybereal: did you look my code. after invoke stop method thread exists in run method.
[20:24:25] <coalado> which results in many harddisk  action
[20:24:27] <cybereal> EdwardIII: I was a biiiig linux advocate before my switch btw, I just got sick of spending hours getting my exotic hardware working
[20:24:28] <dmlloyd> that's pretty big
[20:24:33] <svm_invictvs> pr3d4t0r: what *is* your position at Leapfrog?
[20:24:43] <coalado> (seeking to the current position ->write buffer ->sekk to next buffer position etc)
[20:24:48] <cybereal> thepenguin37: I'm not looking at your code bcause you don't understand threading... what's the point of me looking at your code? read a book.
[20:24:50] <EdwardIII> cybereal: i was very pleased when i heard Apple were going to use a BSD layer for their very pretty pizza topping

[21:18:46] <Riov> hey
[21:20:05] <jamil_1> how does java implement an array ? I have always difficulty in understanding arrays in general. The point that bugs me often, is that how come we have a Data Structure which allows us random access in constant time ?
[21:21:09] <dmlloyd> ~~ jamil_1 arrays
[21:21:09] <javabot> jamil_1, arrays is http://java.sun.com/docs/books/tutorial/java/nutsandbolts/arrays.html
[21:21:23] <cybereal> jamil_1: the data is a linear block, each "slot" is an equal size, and the index multiplied by the size tells you where in memory to look for the item or a reference to the item, either way the complexity doesn't change by the size of the structure so access is reduced to constant time
[21:21:54] <vol> jamil_1: do you mean java's implementation, as compared to say, C?
[21:22:28] <vol> If so, I'm pretty sure that there's a variable that keeps a reference of the size of that array, and get/set operations perform bounds checking against that variable
[21:24:18] <jamil_1> cybereal: Ok even if I get to know where in memory is the required object, but still then how do I access it in Constant time ?
[21:24:30] *** jdolan_ has joined ##java
[21:24:40] <cybereal> jamil_1: do you even know what it means to access something in constant time?
[21:24:51] <jamil_1> vol: No, in general
[21:25:05] <cybereal> jamil_1: all that means is that it will take the same amount of operations/work regardless of the size of the structure/number of elements/whatever that you're working with
[21:25:32] <vol> jamil_1: Do you know how arrays work in languages like C? Basically, you just have a contiguous portion in memory of a pretermined size.
[21:25:36] <cybereal> jamil_1: no matter the size of the array, it requires no more effort to access the value of a given index
[21:25:44] <jamil_1> cybereal: oh yes
[21:25:45] <vol> You then take a pointer into that memory, and add to it the index that you want
[21:25:49] <cybereal> that's all it means to be constant time here
[21:26:03] *** Zvpun has joined ##java
[21:26:07] <jamil_1> cybereal: I got the point
[21:26:19] <vol> jamil_1: The java array isn't a linked list or anything silly like that.
[21:26:39] *** n3llyb0y has quit IRC
[21:27:03] <vol> jamil_1: http://www.cplusplus.com/doc/tutorial/arrays.html
[21:27:28] <vol> Basically, that, except that the java implementation has an internal reference to the size of the array specified, and any get/set operations are bounds checked, so that you don't accidentally go out of bounds

[21:38:55] <chrismaster1> netbeans
[21:38:56] <ernimril> Zvpun: no, they all suck and give you code that you do not want to touch/maintain
[21:39:06] <ernimril> ~~Zvpun layout
[21:39:06] <javabot> Zvpun, layout managers is http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html If the layout managers included with the jdk don't satisfy you, have a look at FormLayout, TableLayout, PercentLayout, HTMLLayout, CentreLayout, or GridLayoutPlus (ask me about each of those to learn more). Book chapter at http://javafaq.mine.nu/lookup?290
[21:39:17] <ernimril> Zvpun: just use the layout managers and write the code by hand
[21:39:31] <ernimril> Zvpun: if you have a paper/whiteboard sketch it is easy to do most layouts

[21:41:30] <Zvpun> since I have no clear idea on it yet I want it mostly to try out things, I think that writing the code by hand is fine later once I have a plan but at the moment I want it to try things and changing the code is alot of work.

[21:42:38] <Zvpun> when I did search the web i found Netbeans but since there are no debian packages in main i didnt want to install netbeans
[21:42:54] <chrismaster1> no problem
[21:42:55] <Zvpun> ernimril: pulling componentts around on the screen.
[21:42:57] <chrismaster1> u only need java
[21:42:59] <ernimril> Zvpun: matisse is the netbeans gui builder you can try it, there is a gui builder for eclipse as well, not sure of the name though, I do not use it
[21:43:06] <ernimril> ~~chrismaster1 aolbonics
[21:43:06] <javabot> chrismaster1, aolbonics is using unnecessary abbreviations such as 'u', 'r', 'ur', 'thx', etc. Using this language depicts you as an imbecile in the eyes of the helpful regulars in this channel, and is generally not tolerated.  If you want intelligent answers, the least you can do is speak intelligently.  Additionally arguing about this rule will get you nowhere except banned.  Have a nice day!
[21:43:30] <ernimril> Zvpun: you are wrong, thinking and drawing a sketch is much faster. Try it
[21:44:15] <chrismaster1> on debian you dont even have to install netbeans, just download the zip file extract it and run the netbeans file
[21:44:18] <Zvpun> alright I consider your suggestions. I was just thinking of the old days back in school where we used Delphi and hoped for something like that.
[21:44:20] <chrismaster1> no installation
[21:44:27] <Zvpun> ok, thanks.
[21:45:03] <ernimril> Zvpun: coming up with a good gui layout is hard, but the hard part of it is not writing the code
[21:45:13] <ernimril> Zvpun: (or drawing the code if you use a gui editor)

[23:16:37] <hse-hoens> pfn using what?
[23:16:49] <pfn> using a JPanel and some ImageIcons
[23:16:57] <kercyr> JLabel and some html?
[23:17:00] <pfn> and JLabels
[23:17:15] <hse-hoens> i see

[23:17:47] <hse-hoens> fair enough i can do that
[23:17:56] <hse-hoens> thanks
[23:18:06] <pfn> I have no idea what you just went on about, but you're welcome
[23:18:12] <kercyr> hse-hoens, you can just override paintComponent(Graphics) on JComponent.  That might be the easiest way.
[23:18:25] <pfn> kercyr, why would any one want to do that
[23:18:26] <blahjake> svm_invictvs: thanks, that makes it clear i was barking up the wrong tree, the type i was parameterizing implements raw-type Comparable not parameterized Comparable
[23:18:27] <svm_invictvs> blahjake: you can use checkecCollection, too, if you're working with an API that doesn't  use generics.
[23:18:30] <pfn> just setIcon on a JLabel
[23:18:33] <pfn> to be the appropriate "light"
[23:18:44] <svm_invictvs> blahjake: that too.  Integer implements comparable, iirc.
[23:18:49] <hse-hoens> yeah exactly pfn, seems much easier :)
[23:19:05] <svm_invictvs> Collections.min(Collection<? extends Comparable> c);

[23:22:46] *** SwanR has joined ##java
[23:23:27] <kercyr> pfn, if you say so.
[23:23:33] <SwanR> Hello, i am trying to get the caret position to always be at the bottom of a JTextArea (so when things are appended , it automatically sticks to the bottom). I have made it go there initially, but when things are appended it does not follow. Could somebody point me in the right direction ?
[23:23:38] <pfn> jlabel.setIcon(new ImageIcon("offlight.png")); jlabel.setIcon(new ImageIcon("onlight.png")); is harder than doing class MyComponent extends JComponent { @Override .. paintComponent(...) { if (on) drawImage(onImage); else drawImage(offImage); } }
[23:23:44] <pfn> right....
[23:24:19] *** jeffmoss has joined ##java
[23:24:20] <pfn> and on top of that, you need a method to modify the 'on' variable, and a request to repaint, at that

[23:27:06] <kercyr> pfn, well... if you want a bunch of these.... maybe.  It wasn't just one blinking light.
[23:27:08] <jeffmoss> something like that?
[23:27:53] <pfn> jeffmoss, define the JMX options in setenv.sh
[23:28:39] <pfn> jeffmoss, add CATALINA_START_OPTS="-Dcom.sun.management.jmxremote.port= ...."
[23:28:48] <pfn> jeffmoss, google for the appropriate jmxremote variables
[23:29:05] <kercyr> I assumed that the number depended on the dimensions of this bar... like a 100x100 box would have 10000 lights on it.
