One is based on a parameter type. i.e. Road Bike / Mountain Bike. The other is an action, i.e. whether this is an upgrade or new order (obviously this example is contrived). The actual base type is the User Interface panel. I need to have something like Road Bike Upgrade, or Mountain Bike Build. Multiple inheritance would be ho
[00:11:45] <slango> I have a lot of parameters for an applet, and I want to check whether they are null or not before assigning them to properties of an object. Is there a smart, shorter way of doing this other than the obvious method that would require either an intermediary variable or two calls to getParameter for each parameter.
[00:12:41] <slango> I know you don't do applet support here, but it's more of a style question... the fact that it's an applet is irrelevant

[00:38:58] <zacs7> or conditional op depends on who you ask.
[00:39:13] <zacs7> ternary is actually incorrect, but it's common practice.
[00:41:31] <DavidC99> zacs7: if you could rename it, to what would you rename it?
[00:42:00] <zacs7> It has a name, conditional operator.
[00:42:11] <DavidC99> so you wouldn't rename it?

[00:43:04] *** [TechGuy] has joined ##java
[00:43:27] <dmlloyd> they call it "the tertiary operator" because it's the only operator with three arguments, thus it's non-ambiguous in the context of Java (and C, and several other languages)
[00:43:44] <zacs7> dmlloyd: that doesn't make it correct.
[00:43:55] <zacs7> And when there is another ternary operator?

[00:44:18] <dmlloyd> zacs7: you honestly believe there's going to be another?

[00:47:00] <zacs7> dmlloyd: then you have a long way to come. Try program anything meaningful in java without maths.
[00:47:01] <dmlloyd> and in Java, there is only one tertiary operator, and it's safe to say there only will ever be one.

[02:03:37] <javabot> cheeser, tij is Thinking in Java by Bruce Eckel, see http://www.mindview.net/Books/TIJ/ for the 3rd edition (free download, published in 2002) or see http://www.mindview.net/Books/TIJ4 for the current edition which covers Java 5 features.

[02:14:28] <cheeser> well, only so many words look like "socket"
[02:14:34] <mhall> cheeser: i'm hoping there would be some way i could, get the thread ids, names, or stacktraces of threads that have a lot of open sockets
[02:14:43] <mhall> cheeser: it only happens under heavy load of course
[02:14:52] <tieTYT> maybe it's a threading issue

[02:15:05] <javabot> a profiler is a tool to find performance bottlenecks. VisualVM is included in JDK nowadays and is great for a free profiler; jprofiler and jprobe cost money (jprofiler has a free eval period). Some more are listed here: http://javafaq.mine.nu/lookup?169

[02:34:55] <Busybyeski> can someone point me to a great explanation of static?
[02:35:00] <cheeser> ~static
[02:35:00] <javabot> cheeser, 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.

[02:47:37] <tieTYT> do you guys prefer one ant script per project or one per module?
[02:47:48] <tieTYT> personally, i prefer the former.  I think it's easier to read
[02:48:08] <govinda> ant is boring
[02:48:23] *** durka42 has quit IRC
[02:48:27] <waz> I despise SWT actually
[02:48:36] <svm_invictvs> depends on how complicated the modules are and how many projects are involved., I'd say.
[02:48:39] <svm_invictvs> waz: why?
[02:48:39] <nDuff> tieTYT, if your project is complex enough that different people maintain different parts, then one-per-module becomes pretty much necessary.
[02:49:06] <nDuff> tieTYT, ...well, maybe not necessary, but certainly a very good idea, as it's obvious who the contact point for any given part of the build process is.
[02:49:29] <svm_invictvs> waz: I know it's not quite as clean as swing but I wrote an app with it.
[02:49:45] <tieTYT> i don't like it either
[02:49:50] <waz> svm_invictvs: it serves no good purpose anymore, breaks java's GC paradigm, is a royal pain in the ass to deploy

[02:51:51] <tieTYT> waz: you mean besides what waz said?
[02:52:02] <svm_invictvs> waz: I found it pretty easy to deploy.  I had to write an ant script to wrap up the dlls and what not with it.  But it was pretty easy for me.  *shrug*
[02:52:17] <tieTYT> i meant to say that to govinda
[02:52:28] <jottinger> I might get to work with SWT soon!
[02:52:33] <govinda> it's very easy to deploy..

[02:57:53] <trustin> cheeser: it will start from explaining some background knowledge about socket programming, nio thing and then.. it will be about netty essentially ;)
[02:57:55] <svm_invictvs> waz: This software really works?
[02:58:03] <tieTYT> but i think that's partially due to my ignorance of nio

[03:08:35] <cheeser> NIO is a bit different
[03:08:39] <JoshJ> ~reflection
[03:08:39] <javabot> JoshJ, reflection is http://java.sun.com/tutorial/reflect
[03:09:13] <svm_invictvs> JoshJ: Reflections allow you to inespct a type's members at runtime.
[03:09:23] <JoshJ> i'm not entirely sure that's what i want
[03:09:33] <svm_invictvs> Hm.
[03:09:53] <svm_invictvs> Does proguard remove interfaces from your code?
[03:10:17] <JoshJ> okay, say i'm working with election data, and i've got a class with fields ObamaPct and McCainPct and I simply want to write a function that returns whichever field is higher
[03:10:23] <cheeser> why would it?  *how* could it?
[03:10:50] <svm_invictvs> cheeser: to save space, and apparently it does.
[03:10:51] <JoshJ> i'd really rather not do something like public static final int obama = 1; then have a pile of if statements
[03:11:01] <svm_invictvs> cheeser: in some cases, you could, no?
[03:11:25] <cheeser> svm_invictvs: well, i don't think you'd need it to invoke methods, but you'd certainly need it for method resolution
[03:11:27] <mdmkolbe> What is the proper way to read a line from standard in?  System.console().readLine()?
[03:11:38] <cheeser> mdmkolbe: if that works, why not?
[03:11:55] <r0bby> mdmkolbe: Scanner
[03:11:59] <JoshJ> scanner's good
[03:12:00] <mdmkolbe> cheeser: in DrJava it gave me a null pointer error

[03:12:22] <cheeser> ~~ mdmkolbe newbie ide
[03:12:23] <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.

[03:13:52] <JoshJ> hm... getDeclaredField might be what i want
[03:14:02] <mdmkolbe> cheeser: heh, while I completely agree with that statement, I'm not a newbie to programming.  I learned Java ~10 years ago but moved on to other languages.  Now things have changed and I'm a little rusty on Java's ideosyncrosys
[03:14:03] *** npm has quit IRC
[03:14:20] <cheeser> mdmkolbe: DrJava is hardly the best tool for that.
[03:14:39] <svm_invictvs> cheeser: I don't know.  I don't know java at the bytecode level well enough.
[03:14:46] <cheeser> svm_invictvs: i don't either
[03:14:47] <svm_invictvs> cheeser: Apparently it does somehow.
[03:14:51] <mdmkolbe> cheeser: I needed a REPL for what I was doing (if there is a better one I'm up for it).  Other than REPLing I use Emacs
[03:15:11] <JoshJ> question about getDeclaredFields(): it says that they "are not in any particular order" but will they at least be consistent?
[03:15:12] <cheeser> i have no idea what REPL is
[03:15:17] <pr3d4t0r> mdmkolbe: Idiosyncrasies.
[03:15:22] <JoshJ> mdmkolbe, try beanshell maybe
[03:15:24] <cheeser> JoshJ: not necessarily
[03:15:33] <JoshJ> cheeser, damn. that makes my life harder =\
[03:15:47] <pr3d4t0r> Hrm... it looks like I'll have to learn to live with Eclipse for a while.
[03:16:14] <nDuff> cheeser, read/eval/print loop
[03:16:27] <pr3d4t0r> . o O o .
[03:16:27] <mdmkolbe> cheeser: REPL = Read Eval Print Loop = an interative prompt allowing you to type in expressions directly (common in Scheme, Python and others)
[03:16:29] <pr3d4t0r> Maybe not.
[03:16:31] <cheeser> nDuff: ah.  thanks.
[03:16:32] <pr3d4t0r> Xcode :)
[03:16:34] <JoshJ> i suppose i could invoke getDeclaredField 7 or 8 times and put them in a constant order myself so I can access them properly
[03:16:41] <cheeser> yeah.  beanshell perhaps
[03:16:44] <svm_invictvs> cheeser: If your whole program were this you could remove the interface: http://rafb.net/p/dFQksP92.html
[03:16:52] <JoshJ> wait, hm, the order being inconsistent doesn't matter, it's a class method :D
[03:17:02] <mdmkolbe> cheeser: it's useful to help quickly run testcases on student papers for this java course I'm TAing for
[03:17:04] <JoshJ> or er, a Class method. so i only have to call it once :D

[03:21:18] <pr3d4t0r> javahorn: Depending on whether it's a for-profit or a JUG who organizes the conference, I'll only ask for them to cover either the air fare, the hotels, or both.

[04:28:29] <r0bby> Map<String,String>
[04:28:47] <JoshJ> r0bby, i need it to be an arbitrary type
[04:28:49] <r0bby> replace String,String w/ whatever the type of your Key and value
[04:28:51] <JoshJ> that is, whatever is passed in
[04:28:55] <JoshJ> i'm doing reflection-related stuff
[04:29:06] <da_shadow> JoshJ, well, how are you passing in attribute, can't you just use that type?
[04:29:10] <JoshJ> da_shadow, it's a Field
[04:29:26] <r0bby> JoshJ: you could ditch generics
[04:29:33] <JoshJ> r0bby, that does not apply to this situation :(
[04:29:37] <da_shadow> JoshJ: so Map<Field, Integer> ?
[04:29:50] *** kater has joined ##java
[04:29:51] <JoshJ> da_shadow, that won't do what i want, will it? the Field is going to be the same every time
[04:30:17] <JoshJ> what i want to do is make a thing to count, so if the field is an integer this time around i want to count how many 33s and 34s etc I have
[04:30:26] <JoshJ> if it's strings I want to count how many ABCs and XYZs i have
[04:30:40] <r0bby> JoshJ: HashMap<Object,Integer>
[04:30:45] <r0bby> that will work for all instances.
[04:30:47] *** kater_ has quit IRC
[04:30:59] <JoshJ> won't Object treat every single one as unique because they're all different objects?
[04:31:00] <da_shadow> So you want to find out how many String fields there are and how many Integer fields there are?
[04:31:12] <JoshJ> da_shadow, no, there's exactly ONE field on any given call of this function
[04:31:22] *** whaley has quit IRC
[04:31:24] <JoshJ> but i've got over 1000 things in a list and i'm not going to call it for the same field every time
[04:31:39] <JoshJ> so if i'm looking into the number field this time around, i want to count instances of those numbers

[04:32:49] <r0bby> JoshJ: generics don't exist at runtime, you know this right?
[04:33:10] <r0bby> due to type erasure
[04:33:16] <JoshJ> so <Object, Integer> will do what I want?
[04:33:23] <r0bby> HashMap<String,String> is just HashMap at runtime
[04:33:35] <r0bby> JoshJ: yeh just do instanceof checks

[04:33:49] *** Pupeno has quit IRC
[04:33:57] <JoshJ> well i already know for a fact that they're going to be the same every time so typechecking isn't an issue this time around

[04:56:44] <Luminari> I have a floating point value between 1 and 5.  Each whole number represents 1 star, after the whole number if there is at least a .5 it represents half a star, and then any whole numbers left to 5 represent no-star.  Any ideas on how to efficiently calculate this?
[04:57:36] <JoshJ> you mean whole numbers less than .5 are no stars?
[04:58:02] <Luminari> I mean if the value is 3.5 we would have 3 stars, 1 half star and 1 no-star
[04:58:50] <linxuz3r> if you have a class and defined a main inside the class is the main considered to be with in the class?
[04:59:10] <linxuz3r> im trying to understand static methods and variables and what good it is for
[04:59:13] <reverend> it's a static method of the class.

[05:09:20] <Chat452> like myOutput.write(<class>.printf("formatting", ...))
[05:09:28] <da_shadow> reverend: But you generally just backup files. Java can access files on the host machine. It can then open remote connections to servers. I don't see what would be frighteningly wrong with the idea
[05:09:39] <pstickne_> twdsje:  there is no reason in particular that a sort implementation couldn't use insertion sort in certain cases internally -- I know of no official SDK api to do so

[06:04:49] <Deiselton> question: does anyone know a way to return the number of chars in a string at a specific index of an arraylist of strings?
[06:05:30] <Luminari> list.get(index).length
[06:07:19] <cmdr_awsome> would there be any way to change the java response header with a xmlhttprequest so that crossdomain works
[06:08:07] <Luminari> cmdr_awsome: browsers will not let you send ajax requests cross domain.  If you want to do that you'll need a proxy on your server to do it
[06:09:19] <Luminari> cmdr_awsome: and server can't spoof another domain no
[06:09:42] *** alek_b has joined ##java
[06:09:48] <cmdr_awsome> I was thinking by maybe changing the header or something in the response
[06:09:53] <SoraCross> Hello
[06:10:06] <Luminari> cmdr_awsome: the server does not use the header to get the ip address
[06:10:15] <SoraCross> Can someone please tell me why this won't work? It seems really simple: http://pastebin.com/m334532ed
[06:10:16] <Luminari> err browser
[06:10:56] <da_shadow> SoraCross: i is not static
[06:11:18] <SoraCross> aside of that?
[06:11:28] <SoraCross> I mean what's wrong with the if statement
[06:11:43] <reverend> haha
[06:12:12] <SoraCross> I mean after it loops 15(?) times it should make the if statement true, and print hello, but it doesn't.

[06:16:26] <SoraCross> Here's a more updated one that actually compiles: http://pastebin.com/mb27297b
[06:17:28] <SoraCross> now 0xFF000000 - 0x11000000 should = 0xEE000000, right? and than -11 more should be DD, than CC than BB, etc.

[06:22:04] <Luminari> Deiselton: the for loops initialize x and check i, so they never end

[06:23:34] <da_shadow> SoraCross: d = 13, 13 is an odd number, odd numbers have a final bit of 1. When compared with a value of 1, the bit comparison comes out true. I think this explains it
[06:24:25] <Luminari> Fanook: I'm basically trying to replicate the way digg displays the time on articles

[06:27:20] <svm_invictvs> Fanook: Checking out the latest code.
[06:27:49] <Deiselton> ok i got a question.... i am using the .add(index, )
[06:28:26] <da_shadow> SoraCross, Fanook: http://pastebin.com/m5dac7a4f If you print out the numbers as a binary string, you can see where the & compares and the 1's line up
[06:29:00] <Deiselton> ok i got a question.... i am using the .add(index, String) line to add a string to an array list.. but instead of just copying over what was there it adds and bumps it over so it contiuously add values
[06:29:16] <Deiselton> how do i replace an idex location in an arraylist?
[06:29:59] <SoraCross> So... is there a way to compare in hex instead of in bianary?
[06:30:02] <da_shadow> Deiselton: You would use the api to read that it has a "set(int index, E element) " method
[06:30:19] <Deiselton> lol ive been reading just missed that i guess

[06:31:38] <da_shadow> SoraCross: Well, what I think you want is to test if the values is less than 0x0FFFFFF, I don't think you need to do the bitwise and
[06:33:29] <SoraCross> I'm using it to test colors though
[06:33:43] <SoraCross> I.E. 0xAARRGGBB
[06:33:55] <SoraCross> I need to see if the alpha is at 00
[06:34:00] <Simucal> What are you testing colors for?
[06:34:02] <Simucal> ah
[06:34:07] *** Dumbell has quit IRC
[06:34:40] <Simucal> can't you use Java's color class, and getAlpha()
[06:35:31] <SoraCross> I'm trying to do it with the int so it'll be light weight
[06:35:48] <SoraCross> I'm going to have this testing like 1000 times a minute.
[06:36:08] <Simucal> Even with java's color a modest computer could do a million in a second
[06:36:16] <Luminari> 1000 times a minute isn't really that much

[07:27:08] <wans> String[] a;   String a[];  Whats the difference?
[07:27:14] <Simucal> there is none
[07:27:27] <Simucal> you can declare an array via it's type or it's name
[07:27:32] <Simucal> its*
[07:27:48] <wans> Thanks Simucal
[07:27:52] <wans> One more question
[07:28:15] <wans> How can I change a char[] to a String[]
[07:28:24] <Fanook> how do you propose to do that?
[07:28:35] <Simucal> Do you want to change a char[] to a String you mean?
[07:28:51] <Simucal> a char[] is an array of characters
[07:28:56] <wans> i mean get all the characters from a char array and get a single String sorry
[07:29:03] <Fanook> ~~ wans javadoc String
[07:29:04] <javabot> wans: http://is.gd/6UoM [java.lang.String]
[07:29:04] <wans> sorry, mistake
[07:29:13] <Simucal> String myString = new String(myCharArray);
[07:29:21] <Simucal> specify an encoding if you want unicode or such
[07:29:40] <wans> No
[07:29:50] <wans> I cant use the Api
[07:30:00] <Fanook> then you're SOL
[07:30:02] <Simucal> You can't use the string methods?
[07:30:47] <Simucal> If you are creating a char array, how is that any different than having to create another variable of type String?
[07:30:52] <Fanook> what restrictions exactly did your prof impose on you (since there's no valid reason not to use a constructor to create a new instance of a class)
[07:30:54] <wans> No I think I cant use them, is any other way to do it without the api?
[07:31:19] <linuxuz3r> should you always have a default constructor
[07:31:34] <linuxuz3r> im looking at a book that has a constructor with a parameter
[07:31:53] <Fanook> linuxuz3r: that depends on how you want your callers to construct the object
[07:32:04] <wans> I have the char[] now i need to create from them a String and then i must read that String char by char and get the number of times that each char appears
[07:32:22] <Fanook> wans: why not just iterate over the char[] you already have?
[07:32:39] <Simucal> Fanook: Yea, I bet that is what his teacher wants him to do
[07:32:45] <wans> Ok let me figure out how to do it hehe
[07:33:01] <Fanook> linuxuz3r: not providing a constructor for a class member means you better have a valid default value for it
[07:33:16] <Fanook> s/for a/that includes

[07:43:34] *** B|ackPanther has joined ##java
[07:44:01] <Sou|cutter> I'm pretty cold to the idea of unit tests touching a db at all, but you at least gotta make it work so that two people can run the test at the same time
[07:44:09] <Sou|cutter> I call that an integration test
[07:44:29] <Fanook> ouch
[07:44:47] *** manunderground has joined ##java
[07:45:03] <Fanook> we have db unit tests too, but our setup uses machine-local db's for our unit testing :)
[07:45:15] <manunderground> for an annotation can you have a String property which defaults to the annotated type's name?
[07:45:26] <Fanook> probably
[07:45:29] <Fanook> ~annotations
[07:45:29] <javabot> Fanook, annotations is http://java.sun.com/j2se/1.5.0/docs/guide/language/annotations.html
[07:45:46] <Fanook> oh wait, misread. No, you probably can't do that
[07:45:50] <Sou|cutter> Fanook: we have too much oracle junk to be able to do that
[07:45:57] <manunderground> Fanook: thanks I was looking that but it wasn't clear
[07:46:02] <manunderground> or rather I didn't see anything
[07:46:03] <Sou|cutter> that is a sensible approach tho
[07:46:35] <Fanook> Sou|cutter: even with our setup, we have some very stupid unit tests (like asserting a class has a specific number of subclasses)
[07:46:56] <Sou|cutter> Fanook: where do people come up with this stuff?
[07:47:06] <Fanook> ew even have one that breaks if you run it multiple times

[07:47:15] <Fanook> *we
[07:47:50] <Sou|cutter> doesn't it make you kinda lose faith?
[07:48:00] <manunderground> I guess it's not possible to somehow set a default like this, bummer
[07:48:41] <Fanook> a bit. we kinda work around our test policy by not making things public (only have to write tests for public methods) :)
[07:48:43] *** Mike-N-Go has joined ##java
[07:49:26] <Sou|cutter> that makes sense, though -- only need to test the interface
[07:49:43] <Sou|cutter> or do you mean public as in published api?
[07:49:59] <Sou|cutter> still applicable I suppose
[07:50:16] <Fanook> published api. anything not private, protected, or internal (this is C# code) is supposed to have a unit test
[07:50:25] *** gdoko has quit IRC
[07:51:05] <Fanook> so we end up testing the api, not the functional units. Six of one, half dozen of the other i guess
[07:51:34] <Sou|cutter> unit tests need to be taken with a healthy dose of pragmatism I think
[07:53:07] <_W_> Fanook, A) only ever use private and public B) have one class do one thing
[07:53:11] <_W_> and your policy would be good

[09:11:23] <thegraham> Hi there - what's the easiest way to create a window with an image as its background and three other images (possible icons with text) at specific pixel points on top of the background one? I've looked at the various swing methods, but can't work out which one I should use and how to use it...
[09:12:30] <mohadib> thegraham: override patinComponent
[09:12:47] <mohadib> for the background
[09:12:58] <mohadib> then just add jlables for the other three images

[09:22:47] <thegraham> mohadib: why does paintComponent need to be overridden? what added things do i need to write?
[09:22:48] <W_work> `House`, if you don't understand anything, the least thing you should worry about is performance
[09:23:05] <mohadib> thegraham: you will paint the background img in that method
[09:23:15] <mohadib> thegraham: jpanels dont have a method called setBgImg
[09:23:21] <mohadib> so you have to do that shit yourself
[09:23:28] <mohadib> or start playing with z-order etc
[09:23:36] <mohadib> or make a custom panelui

[09:38:01] <W_work> "If for the URL's protocol (such as HTTP or JAR), there exists a public, specialized URLConnection subclass belonging to one of the following packages or one of their subpackages: java.lang, java.io, java.util, java.net, the connection returned will be of that subclass. For example, for HTTP an HttpURLConnection will be returned, and for JAR a JarURLConnection will be returned. "
[09:39:52] *** bindaas has joined ##java
[09:41:56] <W_work> I'm been thinking about what I smell from that API - I guess it's that there isn't a HttpUrl, a JarUrl and so on.

[09:45:21] <zmyrgel> If I make class with protected method, can class whose attribute this class is use that method?
[09:48:19] <thnee> i am doing this: <% response.addHeader("Location", (String)request.getAttribute("playUrl")); %> instead of the previous: <meta http-equiv="refresh" content="0; url=${requestScope.playUrl}" /> to redirect the user. but the new method doesnt send me to the new page. do i have to specify something more, like the http status code?
[09:50:10] *** ldam has joined ##java
[09:50:18] <thnee> cause in PHP, i just send the header Location, but i also read that PHP defaults to http 302, so thats why i am asking about that specifically.
[09:53:46] <rawblem> zmyrgel,  a protected method can only be accessed by that class or a subclass
[09:53:50] *** Spike1506 has joined ##java
[09:53:58] <rawblem> or sometimes a different class but only if they're in the same package
[09:54:08] <thnee> oh snap, there is a response.sendRedirect()

[09:58:23] <W_work> rawblem, you're mixing things
[09:58:28] <W_work> ~~zmyrgel access modifiers
[09:58:28] <javabot> zmyrgel, access level is one of 'public' ,'private', 'protected', or default a.k.a. package private. They control which code is allowed to access the attribute / call the method. public means: Everybody, 'private' means: Only stuff in this source file.

[09:59:02] <serrghi> is there a way to check if a object implements an interface? (ex: if the object implements the interface, print out x)
[10:01:47] <W_work> serrghi, yes, but you shouldn't want to do that
[10:02:32] <serrghi> why not? :)
[10:02:36] <W_work> the old idiom of tagging interfaces is replaced by annotations, and any other use can be replaced by better things like proper polymorphism, or generics.
[10:03:24] *** ridoo has quit IRC
[10:04:10] <serrghi> i see.
[10:04:32] <elmomalmo> serrghi: W_work may be right in what he's saying but there are other reasons than tagging to find out whether an obejct implements an interface. Class has a method getInterfaces on it. Start with that
[10:06:17] *** dnmo has joined ##java
[10:06:26] <W_work> no, if you really want to find out if an object implements an interface, you don't go messing with Class
[10:06:40] <W_work> that's for if you want to find out if some class implements an interface
[10:07:17] <W_work> serrghi, could you outline your usage a bit, so we get an opportunity to explain how you can improve your code?
[10:09:14] <elmomalmo> W_work: yeah I conceed, instanceof would work better
[10:12:36] <serrghi> sure(this is a school task btw), well i have an automobile registry consistent of different automobile objects (car, motorcycle, truck, bus) which extends an abstract class <automobile>. those objects who transport persons implements an interface IPersontransport, and those who transport goods, have IGoodstransport. I later want to check the total amount of goods/persons the objects can transport. so i want to do this: if object x implemen

[10:14:07] <tieTYT3> i've got this datatype with two fields in it.  One is called the name.  I want to create a List (eventually) that only has unique instances based on the name.  How can I do this without specifically making equals consider them as being equal?

[10:15:31] <W_work> serrghi, so?
[10:15:32] <tieTYT3> W_work: alrighty, thanks
[10:15:53] <serrghi> it defines what types of vehicle transports what.
[10:15:55] <tieTYT3> W_work: I guess that is the best choice since i'd have to do something unholy to decide which of the two to keep
[10:15:56] <W_work> serrghi, if it's dictated that you should do it the wrong way, either protest or go along with it, but keep it away from us...
[10:16:42] <serrghi> hehe:P sorry then.
[10:16:49] <serrghi> but instanceof whould do the trick?
[10:16:57] <W_work> ~tias

[11:09:42] <neshaug> NiSoOo: main thing is that you can make things general, like have a collection of classes that does different stuff, but can be used as the same "class" since they are all using the same interface.

[13:12:30] <jottinger> Liquid_Fire: there isn't a quick and easy way.
[13:12:41] <W_work> a loop seems fairly quick and easy
[13:12:46] <FooBarWidget> is it possible to: 1) load a potentially unknown, untrusted java class,   2) run that code in its own thread,    3) force that code or that thread to exit if it takes too much time?
[13:12:52] <wans> so, i need to initialize it, but i dont know whats wrong with cause i get only 1 letter from a file on which there are 3 letter a written at

[13:16:02] <FooBarWidget> then is there anything in the jvm that's comparable to .NET domains? in .NET domains you can load code in a domain. if you kill the domain then all code and all resources allocated inside that domain are freed
[13:16:11] *** morkar- has joined ##java
[13:16:11] <jottinger> FooBarWidget: classloaders.
[13:16:59] <FooBarWidget> jottinger: so, I can load unknown code with a custom class loader, then run that code in a thread, then call Thread.stop if it takes too much time, and all resources used by that code is guaranteed to be freed just like .NET domains?
[13:17:15] <W_work> FooBarWidget, I don't know how domains work. Java's class loaders are not that clean, especially as threads holds reference to class loaders
[13:17:17] *** eduardopl has joined ##java
[13:17:25] <jottinger> FooBarWidget: no.
[13:17:29] <W_work> and code can, unless you restrict it, create new threads
[13:17:36] <jottinger> But classloaders can be used to do similar things. think OSGi.

[13:17:50] <FooBarWidget> W_work: yes. so is there a way to kill all those other threads too?
[13:18:19] <FooBarWidget> basically I'm looking for a way to tell the jvm to stop and release every resource that was ever created by the loaded code
[13:18:42] <FooBarWidget> given that I take the proper precautions so that the code can't modify any of the loader's state
[13:18:42] <W_work> FooBarWidget, you can have your own thread group. But Thread.stop has consequences that might be subtle, and depend on implementations of the API classes
[13:18:59] <midbit> jottinger: still there ?
[13:19:05] <jottinger> midbit: sadly, yes
[13:19:08] <W_work> which might (I don't know the details to sufficient degree) lead to resources not being cleaned up
[13:19:16] <jottinger> but I'm putting on my shoes because I am hungry.
[13:19:20] <elmomalmo> thnee: Don't know, does it support EL?
[13:19:42] <midbit> jottinger: no, i cannot use <img> as the image created is a dynamic one which isn't being stored in any disk location
[13:19:51] <thnee> elmomalmo: dunno, what is EL?
[13:20:11] <Fanook> FooBarWidget: Thread.stop() should never be called. Its implementation contains race conditions. the preferred method is to set a flag and have the thread you want to stop periodically check the flag.
[13:20:13] <jottinger> midbit: you DO realise that <img> could always use a src like "http://hostname/servlet/imageGenerator", of course

[13:20:16] *** DragonLord- has joined ##java
[13:20:17] <javabot> for a tutorial on java ee see http://java.sun.com/javaee/5/docs/tutorial/doc/
[13:20:37] <jottinger> You're very lucky, my sarcasm field almost caught you
[13:20:50] <midbit> lol
[13:20:50] <jottinger> It still might, because that was kind of stupid of you to say
[13:21:07] <midbit> jottinger: but the image being generated requires POST info
[13:21:14] <midbit> so i cannot just link it that way
[13:21:16] <FooBarWidget> well what I'm trying to do is to write an application server for web applications. some applications might have deadlock bugs or infinite loop bugs. I want to be able to kill those applications without killing the entire JVM
[13:21:22] <jottinger> midbit: Then store it in session and pull it out in the other servlet.
[13:21:24] <elmomalmo> thnee: not sure that's right, I mean expression language
[13:21:35] <FooBarWidget> but from the responses here it sounds like I should run each application in its own JVM if I want that amount of control
[13:21:51] <jottinger> FooBarWidget: errr
[13:21:51] <jottinger> FooBarWidget: why not use an existing app server, since they're able to do that already for you?
[13:21:55] <elmomalmo> ~expression language
[13:21:55] <javabot> elmomalmo, I have no idea what expression language is.
[13:22:07] <jottinger> Just set the security mode on, servers like WebSphere won't allow you to create threads in invalid spheres and stuff like that
[13:22:11] *** csaba has joined ##java
[13:22:27] <FooBarWidget> jottinger: so which existing app servers do this, and how do they do this?
[13:22:28] <thnee> elmomalmo: right, some sort of standard way of evaluating these expressions, i dont think it does. because not empty doesnt work
[13:22:31] <FooBarWidget> how can I implement the same thing?
[13:22:33] <jottinger> classloaders *are* the way to do that, classloaders and the security manager; the security manager prevents allocation of resources that can't be externally managed
[13:22:43] <midbit> jottinger: so <img> with the link to the other servetl which just writes to the output stream as image will work ? hrm
[13:23:04] <jottinger> so a servlet engine can't fire up a thread in a compliant security manager, which means there are no resources that can be allocated that de-allocating the classloader cannot clean up
[13:23:32] <jottinger> midbit: It's how I'd do it.
[13:23:54] <FooBarWidget> so, I load an application and tell the security manager that that application may not spawn threads, and this would allow me to safely call Thread.stop?
[13:24:02] <FooBarWidget> is this how it's implemented?
[13:24:10] <jottinger> errrr
[13:24:13] <midbit> hmm ok i can try it that way, thanks jottinger
[13:24:17] <FooBarWidget> if that's not is, then how does it work?
[13:24:22] <FooBarWidget> *not it
[13:24:29] <jottinger> something like that, although you'd still call thread.interrupt() and not stop() :)
[13:24:55] <jottinger> you'd restrict more than just thread creation, BTW
[13:24:59] <FooBarWidget> right. but, let's say that the app has an infinite loop bug, somewhere along the lines of while (true) { ...non-interruptable-code....}
[13:25:08] <FooBarWidget> then interrupt() wouldn't work, would it?
[13:25:22] <FooBarWidget> are existing java app servers able to kill the application in this case?
[13:25:24] <jottinger> how does code become non-interruptable?
[13:25:45] <FooBarWidget> as far as I know, Thread.interrupt() causes a thread to raise an interruption exception only at well-defined points
[13:25:50] * jottinger is in hungry-socrates mode
[13:25:58] <FooBarWidget> and not at arbitrary points
[13:26:00] <jottinger> FooBarWidget: like "between atomic statements," right
[13:26:02] <Fanook> foo-nix: interrupt() doesn't atually do anything. and the exception only matters if the app is listening for it
[13:26:04] <FooBarWidget> for example, while (true) { /* nothing */ }
[13:26:18] <Fanook> er @ FooBarWidget
[13:26:25] <jottinger> look, I'm hungry
[13:26:29] <jottinger> I'm therefore AFK
[13:26:33] <roots-> interrupt only interrupts a few things
[13:26:37] <roots-> like wait or notify
[13:26:43] <FooBarWidget> what roots- said
[13:27:02] <roots-> cancellation of threads requires cooperation from those threads
[13:27:27] <Fanook> FooBarWidget: it sounds like you should go read JCIP
[13:27:31] <Fanook> ~~ FooBarWidget jcip
[13:27:32] <javabot> FooBarWidget, jcip is Java Concurrency In Practice, a book focused on implementing threaded and concurrent applications in Java.  http://jcip.net/
[13:27:50] <FooBarWidget> Fanook: I'm not trying to write concurrent code
[13:28:09] <FooBarWidget> I'm trying to learn how java application servers can kill misbehaving applications without killing the entire JVM
[13:28:12] <Fanook> the fact that you're asking us about Thread means you are
[13:28:27] <FooBarWidget> no, I'm asking about Thread because I want to know whether Thread.stop is the way to implement this
[13:28:32] <FooBarWidget> not because I'm writing multithreading code
[13:28:58] <Fanook> and a trivial look at the docs would tell you that Thread.stop() is deprecated and even gives you a link to why and what to do instead
[13:29:15] <FooBarWidget> Fanook, you seem like an expert on this subject. do you know how a java application server can kill a misbehaving application without killing the entire JVM?
[13:29:21] <Fanook> regardless, JCIP contains a rather complete explanation of how the concurrency model works
[13:29:30] *** morkar- has quit IRC
[13:30:23] <FooBarWidget> Fanook: I am trying to write a java application server for an educational project
[13:30:30] <Fanook> FooBarWidget: nope, 1) i've never seriously used an app server, so I don't know their inner workings. 2) as far as the system is concerned, the running app *is* the JVM
[13:30:30] *** justafish has quit IRC
[13:30:34] <FooBarWidget> this application server has to continue running even if the containing application misbehaves
[13:30:44] <Fanook> FooBarWidget: then you ARE doing concurrent programming and you need to read JCIP
[13:31:07] *** teralaser has quit IRC
[13:31:10] <FooBarWidget> Fanook: okay, I will. but the question remains this: can I kill the application without killing the JVM?
[13:31:26] <FooBarWidget> I promise you I will read the JCIP and whatever other things you think I need to read
[13:31:44] <Fanook> like we said before, probably not unless the apps you're running cooperate with you
[13:32:16] <FooBarWidget> okay, so basically, if the app was written by someone else, and it has bugs, and I'm not allowed to modify its source code, then my application server is screwed?
[13:32:35] <Fanook> if you plan on running everything in the same VM, yes.
[13:32:47] <FooBarWidget> right, thank you. that was what I wanted to know
[13:32:59] *** skoskav has joined ##java

[13:36:57] <luiX_> what library do you recommend for working wtih pdf files? the idea is to add some text to an original pdf file from the application
[13:36:58] <W_work> provably correct code, or code that works 99.9% of the time
[13:37:47] <W_work> Thread.stop, while deprecated, and with possible side effects on anything that replies on synchronization for valid object state, might well work for almost all code you will run
[13:38:11] <paulweb515> ~~ luiX_ itext
[13:38:11] <javabot> luiX_, itext is a library for creating pdfs. It is available under either the GPL or the MPL. For more information see: http://www.lowagie.com/iText/

[13:39:03] <luiX_> paulweb515, had a look to itext, i was asking to see if there was any other "better" or more known than that one. Thanks !!
[13:39:11] <W_work> or the pragmatic version of it, which is that analyzing code is hard

[13:39:32] <paulweb515> luiX_: that's one that I've heard of the most (although there might be others)

[13:40:44] <W_work> if you assume all code is nice and clean in the first place, you don't actually need to kill threads at all
[13:41:12] <roots-> itext works ok for simple stuff
[13:41:37] *** skoskav has quit IRC
[13:41:47] <roots-> in general the idea to generate pdf is questionable and to get high quality output that looks like newsweek requires massive effort
[13:44:16] <roots-> on the thread stop problem. though there is technical reasons for the way things are, the requirement of killing a thread/task preemptively just exists
[13:44:27] <kercyr> W_work, the bytecode must be easier to analyze... any jumps of any sort can be rewritten to check for a flag.
[13:46:02] <W_work> kercyr, there's a lot of jumps, but even ignoring the performance problems of rewriting them all, there is also exceptions, which are harder to analyze in bytecode than in source

[14:36:53] *** SoraCross has joined ##java
[14:37:11] <roots-> when you use javah to generate the stub for your native java method, it will generate a jobjectarray argument for the java varargs decl.
[14:37:22] <lami1984> thats true
[14:37:48] <roots-> so consider that information gone
[14:37:56] <roots-> from a jni perspective the java varargs dont exist

[16:01:26] <javabot> Try it and see. You learn much more by experimentation than by asking without having even tried.
[16:01:28] <ojacobson> any solution that would generate an easier-to-parse format could just do the parsing instead, frustratingly
[16:01:34] <ojacobson> (eg. custom doclets)
[16:01:36] <r0bby> I may later on
[16:01:54] <r0bby> i think groovy in action used nekohtml for scraping

[16:20:10] <thommy_> Hi. Does anyone know the best way to integrate an existing database into a java application?Actually i wrote a class for any Table and a general IO class which reads the contents from the database and returns them as Objects. But there are problems with Objects representing the same Row in the database.... so I read about "Hibernate", but I don't know if this would make it easyer or if this is more overkill.... My application is the only
[16:20:11] <thommy_> application which accesses the database at one time and i have to read some data, modify it and maybe create some new and then write it or do a complete rollback depending on the user wants to save his changes or not.
[16:20:54] <waz> lots and lots of ways to do that
[16:21:01] <cheeser> i'd use hibernate, personally.  for lighter solutions there is also ibatis and spring-jdbc

[16:42:23] <roots-> erm gtk+ is not java

[16:43:20] <roots-> ah i see

[16:46:20] <lami1984> sidelil: have you tried to change to awt?
[16:46:29] <roots-> you can set properties like "Label.font"

[17:14:17] <_spm_Draget> Is there a way to inherit constructors automatically from a superclass?
[17:14:36] <dmlloyd> constructors aren't inherited
[17:14:59] <dmlloyd> however, the first statement in a constructor must be a call to the superclass constructor (if you don't give one, "super();" is added automatically)
[17:15:43] <dmlloyd> if the superclass doesn't have a constructor that accepts zero arguments, then not specifying a "super(...)" or "this(...)" as the first statement of the constructor is an error

[17:58:38] <paulweb515> FanBoyuk: calls initiated from the constructor don't get overridden (since the subclass object has not been instantiated yet)
[17:59:14] <AlienPenguin> hi, i am experimenting with some jni code under win32 using eclipse, if u put the code in class that extends applet and run it, it works as expected, while if i use a simple class the dynamic loader says it can't find libraries my dll is dependent on.
[17:59:18] <AlienPenguin> Any ideas?
[17:59:19] <blahjake> FanBoyuk: additionally if its private, all calls to it from methods defined in foo will use it even if not called by the constructor
[17:59:41] <AlienPenguin> obviously all the relevant dlls are in the same folder where the main dll (and the class file are located
[17:59:49] *** scorchsaber has joined ##java
[17:59:55] <FanBoyuk> hmm okay, I will take a look at these things, thank you blahjake & paulweb515
[18:00:19] <roots-> alienpenguin: that is not enough
[18:00:31] <roots-> in the simple case you need to set a -Djava.library.path
[18:00:42] *** nashra has quit IRC
[18:00:51] <AlienPenguin> roots-, i set it (within the eclipse settings that is)
[18:01:03] <roots-> paulweb: the overridden method is invoked
[18:01:17] <paulweb515> roots-: it just craps out?
[18:01:21] <AlienPenguin> otherwise it would not find the first dll
[18:01:21] <roots-> and implementation details escape also the subclass can observe the parent class in an uninitialized halfassed state
[18:01:52] <roots-> some libraries are full of it, in practise is not as big as a problem as it may seem, but sometimes it gets at you
[18:01:52] <latebind> FanBoyuk : suggestion, use @Override annotation so that you get compilation errors if you not overriding correctly
[18:02:13] <FanBoyuk> ooh thats handy
[18:02:27] *** eidolon has joined ##java
[18:02:29] <roots-> the override keyword in c-sharp works and has a a purpose, the override annotation in java is not enforced
[18:02:55] <latebind> FanBoyuk : you cannot override a private method,and you cant override a public method and make it private

[18:03:39] <roots-> the override intention is to provide for library and 3rd party code stability
[18:03:43] *** indeterminatus has joined ##java
[18:04:03] <roots-> if i ship a library and invoke a method from my own class then i might end up calling an overridden method and that breaks my library
[18:04:15] <FanBoyuk> so how do you expose the methods to be available for ovrride in child objects without totaly exposing each method?
[18:04:25] <roots-> fan: protected
[18:04:38] <roots-> you also signal your intention by using protected
[18:04:44] <FanBoyuk> oh yes, of course
[18:04:50] <roots-> don't expect too much from those visibility modifiers though
[18:05:21] * svm_invictvs feels the private abstract ran() coming on...
[18:05:47] <latebind> although a lot of people think that extension is evil and should be avoided(using interfaces instead), take the classic example of thread/runnable
[18:06:11] <AlienPenguin> roots-, any other of what it might be?
[18:06:29] <roots-> svm: thats a compile time error
[18:07:01] <svm_invictvs> rant()
[18:07:01] <roots-> though its questionable since classes in the same parent class scope (inner clases i mean) can see each others' private parts
[18:07:06] <svm_invictvs> bah, I screwed up the joke
[18:07:14] <roots-> indeed
[18:07:23] <FanBoyuk> im sure theres a joke in private parts :)

[18:29:24] <cheeser> and permissions to push as well.
[18:29:30] <svm_invictvs> Ot
[18:29:32] <roots-> or hg, we have svn performance problems
[18:29:32] <latebind> its ok now, I'm cloning the new repo
[18:29:45] <roots-> but deployment infrastructure needs to be changed and that department is overloaded
[18:29:48] <svm_invictvs> It's like if everbody working just branched and then you merged it all together...
[18:30:02] <ernimril> roots-: care to define what you mean by performance problems? how large repository?
[18:30:17] <ernimril> roots-: we are looking at a similar move so I am a bit curious
[18:30:19] <svm_invictvs> is it weird tha we install all our software to /home
[18:31:08] <roots-> ernimril: maybe 20 gig
[18:31:15] <AlienPenguin> roots-, thanks for the suggestion, i already used dwalker nad all seems correct, in fact from appletviewer (same code) it works
[18:31:43] <roots-> but the software is smaller, but developed since 2.5 years and its history is big
[18:31:47] <ernimril> roots-: oh, that is quite non-small, how large if you export it? (or rephrased: how much is ancient history)
[18:31:57] <roots-> merges for example take quite a while
[18:32:09] <roots-> we havent done that yet, eg rebuild the repository through a filter
[18:32:14] <svm_invictvs> Does hg do a 3-way merge?
[18:32:31] <roots-> since its client/server and not distributed we'd have downtime
[18:32:38] <ernimril> roots-: hmm, 20 GB is still a lot, do you keep many binary files in svn?
[18:32:40] <roots-> everything depends on the svn
[18:33:02] <roots-> the coding, the bug tracking (eg wired up with bugzilla), own metrics tools and all the automatic deployments, CI
[18:33:43] <roots-> some, but not the graphics, if you start putting your .psd there 20 gig melt away like snow in afrika

[19:14:45] <javabot> paulweb515, IDEA is a non-free (as in beer, as in speech) IDE held in high regard by ##java - and by most professional programmers. See http://www.intellij.com/idea . It's worth every penny - and it's also free for participating open source projects.

[19:15:23] <Apocalisp> BrokenClockwork: Eclipse has some nice features, but IntelliJ IDEA is overall a better tool. If you're comfortable with vim, there's nothing wrong with that.
[19:15:27] <paulweb515> BrokenClockwork: you can do java development with the javadoc and vim (or emacs, or textpad, etc)

[21:19:01] <cybereal> part of the reason to use a UUID is to reduce traceability, so if that isn't a concern it's often easier to make unique ID's, within certain domains, in other ways like that... userid+anumberhere or whatever

[21:52:34] <waz> jssh
[21:52:36] <gnech> so no matter what, the user would have to install JRE (and not just able to execute it to run my program)?
[21:52:38] <waz> or soemthing like that
[21:52:44] <gnech> or something similar
[21:53:01] <waz> gnech: yes! and if that's an issue why would you ever do your program in java
[21:53:08] <ernimril> gnech: not really...
[21:53:09] <nDuff> waz, if I'm targeting a small embedded environment, my whole toolchain is built around gdb-based remote debugging, I don't otherwise have a JVM installed, and I want to do something a robust Java library is available for, gcj makes a lot of sense.
[21:53:11] <waz> there are better choices if you want to go native
[21:53:28] <ernimril> gnech: you can provide a folder with the jre on it and your jar(s) beside and run from that media
[21:53:28] <waz> good luck
[21:53:57] <ernimril> gnech: but that means your must distribute the jre for all systems you care about, that may or may not be a problem

But how do I call the renderer from the window? I cannot pass a reference of the renderer to the window because I need to craete the window first in

[23:50:47] <javabot> cheeser, exceptions is http://java.sun.com/tutorial/essential/exceptions
[23:50:51] <cybereal> Sounds like you're confused between compilation vs. execution
[23:50:55] * cheeser nods.
[23:51:09] <Sou|cutter> that's a compilation error, not an exception
[23:51:20] <cybereal> but yes, there are two types of exceptions and for one type, it tries to make sure that you've handled it

[23:53:13] <cheeser> that link explains it.

[23:53:22] <Sou|cutter> ... yeah, listen to cheeser, read about exceptions
[23:53:23] <cybereal> ScottG489: such behaviors vary between languages
[23:53:24] <ScottG489> yea im reading it
[23:53:35] <Sou|cutter> it'll make sense in no time
[23:53:44] <cheeser> exceptions are looser in c++ because, like most features, they were tacked on after the fact.
[23:53:51] <cybereal> ScottG489: java only looks like C++, it stops being similar quickly after that facade
[23:54:26] <TryNiX> Whenever I asked my lecturers for clarification on Exceptions, I always get varied answers... One lecturer said exceptions should be used to handle every error (even things like wrong password), whereas another lecturer said exceptions should be used only if an error might break the program
[23:54:30] <cheeser> yeah.  java has less suck than c++ and the suck it does have is a whole other variety.
