[00:09:50] <lvh> hi
[00:10:07] <r0bby> mySQLnoob: no way
[00:10:19] <r0bby> ~exe
[00:10:20] <javabot> r0bby, I have no idea what exe is.
[00:10:38] <ernimril> mySQLnoob: pack your program into an executable jar and then the user can double click on that jar
[00:10:47] <lvh> I'm looking for the JDK docs for JRE 6 Update 12. http://java.sun.com/javase/downloads/index.jsp -> scrolling down to the docs gets me jdk-6u10-docs.zip, which is for revision 10
[00:10:47] <r0bby> but yeh
[00:10:50] <lvh> any ideas?
[00:10:54] <ernimril> mySQLnoob: the user will need to have java installed first though
[00:11:16] *** ankou has quit IRC
[00:11:17] <r0bby> mySQLnoob: http://www.google.com/search?q=java+exe&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
[00:11:22] <ernimril> lvh:there should be no api changes between them
[00:11:38] <mySQLnoob> ernimril: i have to run it from cmd.. no clicking
[00:11:39] <r0bby> er that works for windows only
[00:11:49] <r0bby> mySQLnoob: use a shell script.
[00:12:02] <ernimril> mySQLnoob: why use java if you are tied to cmd/windows?
[00:12:05] <mySQLnoob> r0bby: excellent, i was just looking into that but doesnt seem to work
[00:12:18] <r0bby> really? groovy uses it for bootstrapping.
[00:12:33] <mySQLnoob> #! /bin/bash
[00:12:35] <mySQLnoob> java myProgram
[00:12:51] <mySQLnoob> that's what i have in a file and try running myPorgram and it just doesnt
[00:12:52] <r0bby> mySQLnoob: and the problem?
[00:13:05] <r0bby> mySQLnoob: what error?
[00:13:08] <lvh> ernimril: well, but that zip file does exist (other sites on the web reference it), and the debian package i'm using to install the jdk wants it. Would it be safe to just rename the zip file?
[00:13:26] <mySQLnoob> 'dpost' is not recognized as an internal or external command, operable program or batch file.
[00:13:28] <ernimril> lvh: most probably, yes
[00:13:29] <lvh> That'd be weird. I'd expect sun to at least bump the version number, even if nothing changed :-)
[00:13:40] <mySQLnoob> dpost is the name the file with the bash
[00:13:41] <r0bby> mySQLnoob: type java w/o the shell script
[00:13:45] <r0bby> what do you get?
[00:13:57] <r0bby> do you have a JRE/JDK installed?
[00:14:17] <mySQLnoob> r0bby: i do, i can run java myProgram very well
[00:14:24] <r0bby> try doing this: $JAVA_HOME/bin/java MyProgram
[00:14:32] <r0bby> assuming JAVA_HOME is specified.
[00:14:35] <mySQLnoob> at java w/o i get "exception i main thread...... NoClassDeffound.."
[00:14:40] <r0bby> oh
[00:14:45] <r0bby> ~~ mySQLnoob classpath
[00:14:46] <javabot> The classpath tells Java or the compiler in which jar files and folders to look for classes. Use the -cp/-classpath run-time options to specify the classpath. Also see http://is.gd/j4gM [sun.com] for more info.
[00:14:56] <r0bby> java is case-sensitive
[00:14:59] <mySQLnoob> yeah i've used xp before
[00:15:02] <mySQLnoob> cp*
[00:15:17] <r0bby> then use it here
[00:15:22] <r0bby> where is myProgram located?
[00:15:29] <r0bby> where does the JRE look?
[00:15:36] <mySQLnoob> im running it in my bin folder
[00:15:38] <mySQLnoob> where the .class is
[00:15:39] <r0bby> tell it where it needs to look
[00:15:50] <r0bby> then do java -cp . myProgram
[00:15:55] *** Ven]n has quit IRC
[00:16:04] <r0bby> is myProgram in a package or the default package?
[00:16:14] <mySQLnoob> no wait i think there's a misunderstanding............ if i do "java MyProgram" it runs fine
[00:16:22] <mySQLnoob> i dont have any problem with my classpath
[00:16:34] <r0bby> well your error tells me otherwise
[00:16:47] <mySQLnoob> but the shell scripting is not executing it

[00:38:31] <Meddi> Hi guys. I've got a question regarding jtable's. Suppose I created a jtable using JTable table = new JTable() and then used this -> DeafultTableModel model = (DefaultTableModel) table.getModel() . Why does table.getRowCount() return a different value than model.getRowCount() ? ? ?
[00:38:50] <r0bby> cybereal: the "do you believe in life after love?" thing :)
[00:39:07] <cybereal> r0bby: obviously

[01:20:38] *** funktor has quit IRC
[01:21:01] <pstickne> Meddi:  you access something out of bounds. oops.
[01:21:19] *** jcp has joined ##java
[01:21:54] <pstickne> Meddi:  be aware that multi-threading may come into play
[01:21:54] <Meddi> but why does the method work if getColumnCount() is bigger than 5 ??Because whether it is 3 or 5 it is the same thing as it says that there are 3 or 5 columns accordingly.
[01:22:56] <Meddi> and the method just removes those columns.. i dont see why when it returns 5, the 5 columns are removed with no error whilst if it is 3, which means there are 3 columns, it goes out of bound when it tries to remove them :s
[01:23:48] <hoonteke> ant or javac question, not sure which: how do I make the compiler (or ant, since I'm using that) treat warnings as errors and stop on them?
[01:24:09] <hoonteke> I know how to do this with gcc (-Werror or -Wfatal-errors), but not for javac
[01:25:41] *** darkfrog has joined ##java
[01:25:48] <pstickne> Meddi:  put in more debugging output; somewhere in there the data is changing on you and/or not as you expect
[01:25:59] <Meddi> i think i know what it is
[01:26:00] <darkfrog> What is the difference between a "mouse up" event and a "mouse click" event?
[01:26:06] <Meddi> bit i dont know why it happens and how to fix it :S
[01:26:43] <pstickne> Meddi:  well, what do you think it is?
[01:27:08] *** unop_ has joined ##java
[01:27:17] <pstickne> darkfrog:  it's possible that a mouse up doesn't result in a "click"
[01:27:26] <Meddi> I just tried with 3: There are 3 columns in my table. at that time, table.getColumnCount() returns 3, whilst tableModel.getColumnCount() (tableModel is an object which points to table.getModel() ) Returns 4
[01:27:33] <Meddi> do you know why does this happen ?:S
[01:27:35] <hoonteke> darkfrog: mouse up: push button over another object, move mouse over new object, release mouse.  I believe that's a mouse up for the new object.
[01:27:35] <hoonteke> mouse click is when it is both pushed and released over an object.  but ... I'm not sure.
[01:27:38] <pstickne> darkfrog:  imagine mouse-down off area, move mouse onto area, release mouse
[01:28:10] <darkfrog> pstickne: now, what about "key down", "key up", "key typed"?
[01:28:35] <hoonteke> any word an bailing out on warnings as well as errors for javac?
[01:29:10] <gionny> Meddi: did you write your own table model?
[01:29:28] <pstickne> darkfrog:  key-down must be before key-up or key-pressed; I suppose the same thing could apply as with mouse-up vs. mouse-click
[01:30:14] <darkfrog> pstickne: right, but what is the benefit of a "key typed" event over just relying on "key up"?
[01:30:20] <darkfrog> pstickne: type-matic repeat?
[01:30:24] <gionny> Meddi: if you wrote your own table model, be sure to fire the events that you removed something in the code that removes something
[01:30:53] <Meddi> gionny: nop. The way I created the tables, as in http://pastebin.com/d75ed5d3b Was JTable defaultTable1  = new JTable(9,4) . (mind you, the table in the method always uses the defaultTable1 defined above)
[01:31:23] <pstickne> darkfrog:  the biggest thing to me is that is cleaner because you defer the logic to somewhere else; let /them/ key track of all the internals (unless you really do need the plain individual events)
[01:31:38] <gionny> Meddi: I saw the problem, line 111
[01:31:45] <gionny> Meddi: you can't iterate and then remove it
[01:32:07] <pstickne> darkfrog:  that is, think of it simply as an invent interface with fairly well defined semantics. unless you want to change the "meaning" of mouse-click, just let it be :)
[01:32:14] <pstickne> s/invent/event/
[01:32:15] <gionny> Meddi: if you do an iteration with i from 0 to number of rows -1, once you delete one row, then the total value is number or rows - 2...
[01:32:26] <gionny> Meddi: are you following me? that isn't going to work
[01:32:30] <darkfrog> pstickne: valid point
[01:32:47] <Meddi> gionny, ok, why does it work with anything more than 4 though ?
[01:33:06] <darkfrog> pstickne: using you as a sounding board to the philosophical discussion of the UI framework I'm writing. :o
[01:33:24] <Meddi> btw the problem is on line 117. the rows removal works fine
[01:33:29] <darkfrog> ...or rather, re-writing
[01:33:32] <Meddi> what causes the exception is the column removal

[01:34:40] <gionny> Meddi: I don't know why it works in some cases (I should read all the code to understand that), but however it is not correct the way you do it
[01:34:42] <pstickne> gionny:  I'm missing something... because the iterator goes from n-1 to 0... :(
[01:35:10] <gionny> well, even if it is from n-1 to 0, it's a problem
[01:35:21] <pstickne> if you always remove the last item?

[01:36:15] <Meddi> I tries using int j = tableModel.getColumnCount()
[01:36:23] *** darkfrog has quit IRC
[01:36:32] <Meddi> and then used j in the for ( int i = j.. )
[01:36:33] <Meddi> but i suppose its the same thing
[01:36:47] *** Woflborg has quit IRC
[01:37:25] <gionny> Meddi: but what do you want to do? just remove all rows and all columns?
[01:37:44] <Meddi> basically yes
[01:37:50] <pstickne> Meddi:  I think the problem is that there are multiple threads and the dispatch involved; of course I could be wrong
[01:38:18] <Meddi> I just want to clear everything in the table and start constructing it again
[01:38:29] <pstickne> Meddi:  that is, I am fairly certain the /model/ updates happen in the sdt
[01:38:36] <gionny> Meddi: are you sure that there isn't a clear() method in the table model?
[01:38:56] <gionny> why complicate your life if a clear method exists... well, maybe it doesn't exist, I don't remember that
[01:39:01] *** josemoreira has joined ##java

[01:42:30] <Meddi> I found somewhere I clear command but i dont remember it :\
[01:42:42] <Meddi> i tried it actually and i think it removes everything from the model, not the table
[01:43:39] <gionny> Meddi: uhm... if the model is written so that it fires the appropriate events when something is removed, the renderer should re-draw the table to display just what's in the model
[01:44:06] <pstickne> Meddi:  try {  while (has_columns) { remove_last_column} } ... but this is fugly O.o
[01:44:44] <Meddi> ok let me try
[01:44:45] *** vesz has quit IRC
[01:44:49] <Meddi> gionny i am using the defaulttablemodel
[01:44:56] <pstickne> Meddi:  but since you are still split between the EDT and not, it's still prone to be wonky.
[01:45:09] <Meddi> what is EDT?
[01:45:11] <pstickne> (Just suppressed wonkiness)
[01:45:16] <pstickne> Event Dispatch Thread
[01:45:30] <Meddi> ohhok
[01:45:46] <gionny> Meddi: however, something like this should work: for (int i=0; i < numRows - 1; i++) { model.removeRow(0); } ... it's the same that pstickne just said, just that you remove always the first one
[01:46:53] <Meddi> ok i found something easier lol
[01:47:02] <Meddi> table.setModel(new DefaultTableModel());
[01:47:11] <gionny> lol
[01:47:39] <gionny> that works of course, anyways, it should work even in the other way... I'm not sure why it's not working

[01:48:03] *** riotz has quit IRC
[01:48:28] <Meddi> i think the reason is because I dont remove them from the model (?) but i aint sure
[01:48:46] *** ries has joined ##java
[01:48:58] <gionny> Meddi: oh! now I see that you just call a removeColumn() method instead of removing them from the model...
[01:49:20] <Meddi> yes, i just didnt know how to remove the column from the model.. couldnt find any command :\
[01:49:46] <gionny> Meddi: but wait... why are you trying to remove columns if you already removed all rows? I mean... the new table will not have the same columns?
[01:50:27] <gionny> usually the columns are always the same for a model... if you are going to change the columns, then you have to change the model and I guess that it's better to do it as you did, creating a new model
[01:50:41] <Meddi> yes thats what i am trying to do
[01:50:49] *** Banke has quit IRC

[01:52:28] <Meddi> yup, thanks btw :)
[01:53:25] <gionny> it's not a "normal" situation to have the same table changing the number of columns... I think that if you want to change it dinamically without removing elements, then you have to implement your own model
[01:53:49] <gionny> it's not a trivial task, though, it's pretty simple to write a model
[01:53:53] <josip> Hello, I'm using log4j as a logger, with the config file pasted here http://pastebin.ca/1338498 Although I see the output on the console, the file janta.log _is_ created by log4j but nothing is ever written to it. Any ideas?
[01:54:30] <aleksei> Anyone has an idea why JDO isn't that widespread?
[01:54:33] <Meddi> basically the table is not editable. it is used to display stuff about Automata. and since each automaton can have different number of states (columns), i have to change the columns each time
[01:54:39] *** boringwall has joined ##java
[01:55:32] <gionny> Meddi: well, if you have to clear the table and do it again, maybe it's faster to create a new model...
[01:55:36] <pstickne> gionny++ (for the immutability suggestion)
[01:55:43] <Meddi> yup I suppose so!
[01:55:51] <gionny> Meddi: anyways, I just found a setColumnCount() method in DefaultTableModel
[01:55:56] <pstickne> speed won't be an issue, but cleanliness will likely be
[01:56:09] <gionny> so you _can_ do it with simple table model, too
[01:56:30] * Meddi would write if he knew and had time :\
[01:56:36] <Meddi> btw thanks a lot gionny, and pstickne
[01:58:46] <gionny> Meddi: it is very simple to write a table model... you can write one in 5 mins and it allows you to do things better in some cases. I suggest you to spend some time learning that, but... do as you whish!

[02:21:21] <AskHL> What you want to do is to put the value of N into your array

[05:32:39] <thefalling> ok i finally got it to stop the actionlistener, i called pickShips.removeMouseListener(this); inside the listener, but i cant add the listener with pickShips.addMouseListener(this);
[05:33:13] <r0bby> sorry i couldn't help more
[05:33:33] <Csow> pfn  Arrays.asList() does not work here or should not be employed all I want is use an array then use list to add thing in the array
[05:33:43] <r0bby> Csow: it's immutable.
[05:33:52] <thefalling> anyone know a tut for stopping and starting listeners, because the API is just confusing me lol
[05:35:14] <r0bby> Csow: what you CAN do is this: List<String> list = new ArrayList<String>(Arrays.asList({new String[] { "Texas","New York
[05:35:25] <r0bby> Csow: what you CAN do is this: List<String> list = new ArrayList<String>(Arrays.asList({new String[] { "Texas","New York"}));
[05:35:49] <r0bby> NOW you can add/remove elements.
[05:36:09] <r0bby> Csow: what you CAN do is this: List<String> list = new ArrayList<String>(Arrays.asList(new String[] { "Texas","New York"}));
[05:36:14] <r0bby> DOH -NOW- it's right.
[05:36:30] <Csow> ok
[05:36:38] <asap18> 3rd times the charm
[05:36:38] <CodeWar> google collections has useful static methods for constructing Lists with init values
[05:36:50] <r0bby> yeh but this is just as easy.
[05:36:54] <CodeWar> sure
[05:37:05] <r0bby> plus no extra bloat needed
[05:37:53] *** pstickne has joined ##java
[05:38:44] *** Guest33209 has quit IRC
[05:38:56] <CodeWar> actually we could take the RHS part away with a public <T> static T createArrayList(T... input) { ArrayList<T> a  = new ArrayList<T>(); for( T temp: input) { a.add(temp);} }
[05:39:15] <CodeWar> forgot the "return a "
[05:40:24] <r0bby> that requires bringing in a dep. why?
[05:40:51] <r0bby> CodeWar: you could even do
[05:41:14] *** Kwitschibo has quit IRC
[05:41:35] <CodeWar> if it was in the Collections class then we wouldnt have required an extra dep the argument in its favour being some people find writing the new ArrayList<Integer>() a pain.
[05:41:38] *** Kwitschibo has joined ##java
[05:41:43] <r0bby> public <T> static List<T> createArrayList(T ... inputs) { return new ArrayList<T>(Arrays.asList(input)); }
[05:41:47] <CodeWar> its easy for this but wiht Map objects it gets long though IDEs do it for you
[05:42:03] <r0bby> one liner.
[05:42:20] <r0bby> your entire method is now one :)
[05:42:25] <r0bby> line
[05:42:58] <AMcBain> fail
[05:42:59] <CodeWar> r0bby, yes I dont insist on asList vs foreach the static part however makes type inference possible and makes RHS easier to write
[05:43:53] <pstickne> CodeWar:  why not just use a language that /has/ type inference?
[05:44:44] * CodeWar looks in the other direction while Scala folks beat it
[05:44:50] <pstickne> ^^
[05:45:30] <CodeWar> but frankly I found issues with Scala that dont seem to make daily programming easier. Not all clever type inference is good sometimes it just makes the code less easy to read
[05:45:31] <pstickne> CodeWar:  although there are a number of fine statically typed languages with various forms of type inference...
[05:45:51] <pstickne> CodeWar:  what clever inference?
[05:46:19] <CodeWar> public final int myVar = 2; now I happened to skim through Scala presentations that say this can be removed by val or var or some such whcih will make it final and public
[05:46:25] <pstickne> CodeWar:  I can point out some things that /do suck/ in Scala, but the inference isn't one of them
[05:46:29] <CodeWar> clever yes short yes but doesnt tell a clear story :)
[05:46:48] <pstickne> CodeWar:  val myVar = 2 // what is there to talk about?
[05:47:04] <CodeWar> is it public ?
[05:47:07] <pstickne> val myVar: Int = 2 // So what's the problem?
[05:47:08] <CodeWar> is it final?
[05:47:19] <pstickne> CodeWar:  do not think in Java syntax.
[05:47:22] *** cactaur has joined ##java
[05:47:36] <AMcBain> but that's just so easy to do! :P
[05:47:37] <pstickne> CodeWar:  first off, public only applies to class scope, not method scope
[05:47:38] <CodeWar> doesnt matter which langauge public final quoted side by side tell a clear story
[05:47:49] *** TooAngel has joined ##java
[05:47:50] <hiredman> *snort*
[05:47:55] <CodeWar> well i m biased so what
[05:48:17] *** waz has quit IRC
[05:48:33] <pstickne> CodeWar:  so "it depends on if it is in class scope or not"; otherwise, 'public' is the default modifier of all class variables; if it's "val" it means the /variable/ is immutable. if it is "var" it means it is mutable. what is there to talk about?
[05:49:51] <CodeWar> val is immutable vs final is immutable... isnt the later more English
[05:50:03] <pstickne> why don't you use AppleScript?
[05:50:10] <CodeWar> either ways does it add more value to the language
[05:50:24] * CodeWar starts using AppleScript
[05:50:27] <pstickne> CodeWar:  val is so easy to use SO IT WILL BE USED
[05:50:59] <pstickne> CodeWar:  I would say that at least 9/10 of the variables I use in Scala are val. You /can/ do the same in Java, and I do, but it /adds no clarity/.
[05:51:04] <CodeWar> reminds me of C programmers that till date do this and find it soo cool and easy bool getValue(int a ){ return !!a;}
[05:51:57] <CodeWar> the most elegant one liner code bases are not necessarily the easiest to read or maintain but never mind I m just ranting I havent given Scala a clean try so my judgement doesnt count
[05:52:11] <r0bby> wtf
[05:52:14] <r0bby> double negation
[05:52:17] <pstickne> CodeWar:  out of all the problems that Scala has (and it does have some dark corners), this val/var is -not- one of them (well, var might be one of them; some people would preference just references like in SML)
[05:52:22] <pfn> r0bby, simple, returns a 0 or 1
[05:52:29] <CodeWar> pfn, yes
[05:52:33] <pfn> I don't know any c programmers that care to do that, in any case
[05:52:37] <CodeWar> extremely clever and elegant but not clear to read
[05:52:39] <r0bby> if it's 0 then 1 if it's 1 then 0
[05:52:50] <pfn> r0bby, returns a 0 or 1, regardless of the value of a, duh
[05:52:55] <r0bby> hrm
[05:52:57] <pstickne> CodeWar:  first off, why would a C programmer do that? do you know what a true value in C is?
[05:52:58] <CodeWar> r0bby,  if its 50 it will return 1
[05:53:07] <pfn> because if (a) already treats it as a boolean "correctly"
[05:53:24] * r0bby will NOT admit to know C at _ALL_
[05:53:31] <pfn> CodeWar, and if anything, that should be implemented as a macro, not a function  :p
[05:53:33] <r0bby> I know it a basic level and that's about it
[05:53:33] <CodeWar> that instead of getValue(int a ){ if (a == 0){ return FALSE;}else{ return TRUE;}
[05:53:44] <pstickne> CodeWar:  WHY?
[05:53:47] <pstickne> CodeWar:  C fail
[05:53:50] <pfn> a == 0 ? 0 : 1, duh
[05:54:02] <pstickne> CodeWar:  0 is the only false integer. next.
[05:54:11] <pfn> pstickne, indeed
[05:54:44] <CodeWar> pstickne, sorry I didnt follow much of what you typed but I see you seem to disagree :)
[05:54:52] <pstickne> CodeWar:  anyway, start writing code using 'final' as much as possible; it /will/ help you write better code, however it is ungodly unwieldy
[05:55:16] <pstickne> (final for local variables and data members)

[05:56:29] * pstickne smacks twobytes around
[05:57:17] <twobytes> pstickne: is that to help not write bloated code?
[05:57:46] <hiredman> it helps you write code with less concurrency bugs
[05:58:00] *** Thorn has quit IRC
[05:58:01] <pstickne> twobytes:  no; but striving to use final, at least for me, helps to reduce mutable state -- I'm not arguing for complete removal, but it really helps "pull in the scope".

[06:02:21] <pstickne> hiredman:  it looks promising. I'm still a fan of static typing though...

[08:55:15] <jorgenpt> Ah.
[08:55:20] <jorgenpt> Guess I could just cast it, then. :-)
[08:55:32] <letfunbegin> if you want to test that you can just catch that, but it's not so clean since you won't know where it was thrown from :)
[08:55:40] <letfunbegin> therefore instanceof is the win
[08:55:44] <letfunbegin> :)
[08:56:16] <jorgenpt> Well, I don't need a "pretty error", this is more of an assert-type thing. "What the heck? Mr. Programmer, you've done something wrong."

[09:35:12] *** donavan has quit IRC
[09:35:21] <koskoz> i've got my main window, a jpanel
[09:35:44] <koskoz> and a sub window, a jframe, but i can't set a title or even a size to this window
[09:36:02] <koskoz> and i can't figure out why
[09:36:24] <AMcBain> uh ... you shouldn't be able to add a JFrame to another top-level component ... or if you can, it's a very bad idea.
[09:36:34] *** blankthemuffin has joined ##java
[09:36:48] <AMcBain> you might want to investigate JDesktopPane and JInternalFrames.
[09:37:04] <koskoz> ok, i'll check this two components, thanks :)
[09:37:10] *** dnmo has joined ##java
[09:38:32] <AMcBain> I will also tell you, right of the bat, that JInternalFrames tend to look kinda shitty with the (current) default L&F ... they can look better with the system L&F, if you have a good one (on linux they are the same, so it doesn't matter)
[09:38:39] <AMcBain> right off*
[09:39:50] <AMcBain> (just my 2¢)
[09:39:50] <koskoz> if i've understood, my main window should extends JDesktopPane et all the other windows JInterlFrame ?
[09:40:10] *** bas-i has joined ##java
[09:40:10] <AMcBain> ah ... no. you can add JDesktopPane as the content-pane to your default JFrame.
[09:40:26] <AMcBain> then when you add stuff to that JFrame, it'll be on the JDesktopPane.
[09:40:46] <koskoz> no more jpanel ?
[09:41:41] <AMcBain> you can still add JPanels to JDesktopPanes ... but if you were just using that to add your JFrame before, you don't need it. you just add the internal frames directly to the JFrame (which will forward to the content-pane, which is now a desktop-pane)
[09:42:07] <AMcBain> (JDesktopPanes are also useful for making application-modal internal dialogs which are trapped within the application window, reducing their evil to an extent)
[09:42:37] <brady_k> letfunbegin: oh i got it.  http://pastebin.com/d3609dc31  do it after line 18 because "instance" will have a .col value afterwards... duh!
[09:42:40] <brady_k> letfunbegin: thanks though
[09:42:51] <letfunbegin> sure :)
[09:42:55] <koskoz> hum, i'm realy noob to java, and more to swing :/
[09:44:05] <koskoz> AMcBain : for the moment, i've got this : http://pastebin.com/d89823ba
[09:44:06] <AMcBain> well, what are you trying to do? from my perspective, you want to have a JFrame container with a JFrame-like item inside of that.
[09:44:32] <letfunbegin> koskoz, read the swing tutorials: http://java.sun.com/docs/books/tutorial/uiswing/components/index.html    it's time well spent imo
[09:44:32] <koskoz> and in my MenuBar i call my AboutWindow like this :

[09:45:30] <AMcBain> okay, so let me get this straight ... you want a normal JFrame (with whatever layout mangers, etc.) for your regular contents, but the ability to have an internal frame for an about window?
[09:45:45] <koskoz> i think so
[09:46:59] *** mazzachre has joined ##java
[09:47:26] <AMcBain> okay, we're going to "cheat" ... you want to set the glass pane of the outer JFrame to be an instance of a JDesktopPane. Don't forget to do setOpaque(false) on the JDesktopPane before adding it, otherwise it'll obsure everything. Then, after you add it, set it visible. Later on, you should be able to add JInternalFrames to the glass pane and not only will they appear on top of everything, you can still have a normal content-pane (JPanel, etc).

[09:50:43] <koskoz> it's already working, but i can't set its title or even its size
[09:51:13] <AMcBain> you weren't very explicit with your original description then ... you led me to believe that you'd tried to add this window to another JFrame ... which you can't/shouldn't do.
[09:51:38] <AMcBain> (which may result in those problems, I don't know ... I haven't tried)

[09:52:31] <AMcBain> can you pastebin a test case, the minimal code that causes this issue, so that I can check it out?
[09:53:26] <AMcBain> if the issue doesn't exist, maybe something you didn't add to your test case that's present in your real code is the issue. if it still exists, then I'll take a look.

[10:04:12] <mitch0> I ask because of this: "Constraint exclusion only works when the query's WHERE clause contains constants. A parameterized query will not be optimized, since the planner cannot know which partitions the parameter value might select at run time. "

[10:06:12] <cybereal> mitch0: that depends on the driver's implementation, but chances are it's a parameterized query
[10:06:40] <mitch0> hrmp
[10:06:46] <cybereal> mitch0: if you want to try and make a different query for every value as you encounter it (quite stupid depending on the scenario) then there are other escaping options to keep things safe...
[10:06:53] <cybereal> ~jdbc escape syntax
[10:06:53] <javabot> cybereal, jdbc escape syntax is http://java.sun.com/j2se/1.5.0/docs/guide/jdbc/getstart/statement.html#1006519
[10:07:28] <mitch0> cyb: well, I just don't see why can't it do the planning after it sees the actual values...
[10:07:41] <cybereal> because it does the planning before
[10:07:46] <mitch0> I'll take a look into it when I have a bit of time. till then we'll stick with oracle

[10:12:50] <Level1> hi, can NIO be used for network communication as a replacement for sockets, or is that a misunderstanding of NIO?
[10:13:03] <cybereal> it doesn't replace sockets at all
[10:13:07] <cybereal> or any of your basic I/O outlets
[10:13:12] <Level1> ic, my mistake
[10:13:19] *** Levia has joined ##java
[10:13:32] <cybereal> it's just a different API for interacting with it, based on selectors, like basicallye very other language had for years before via support or emulation for c's poll() call :)
[10:13:49] <cybereal> so NIO is ideal when you need to deal with asynchronous I/O
[10:14:12] <Level1> if I want to implement a very exotic network, should I just use sockets or is there a better way?
[10:14:39] <cybereal> Sockets are a high level piece of an already implemented network, so your question doesn't make much sense to me
[10:15:28] <Level1> well, I was refering to application layer
[10:15:29] <mitch0> nio is preferable even if you don't need async operation because of its use of Buffers
[10:17:16] <Level1> is there a class that represents ip addresses?
[10:17:29] <mitch0> InetAddress?
[10:17:31] <AMcBain> ~~Level1 InetAddreess
[10:17:31] <javabot> Level1, I have no idea what InetAddreess is.
[10:17:37] <AMcBain> ~~Level1 javadoc InetAddress

[10:45:04] <isr`> so if i have an exit menu item, and of course the X box, but If the user clicks either without saving, how can I make sure both methods show a dialog asking the user if he wants to save
[10:45:53] <AMcBain> have them both call a common method.
[10:46:15] <AMcBain> (just make sure the onClosing even is canceled if they haven't saved, so it doesn't close anyways)
[10:46:32] <AMcBain> Plus points to Java for getting the onClosing event right.

[11:09:10] *** Jonny_ has joined ##java
[11:09:41] *** arpu has joined ##java
[11:09:43] <AMcBain> I'd think that's pretty obvious (for the compression) ... the path info means they probably don't want the folders "Program Files/Java/xxx" they just want the folder for that particular jre
[11:10:01] <Jonny_> Any SQL exports here? ##sql seems to be fairly empty
[11:10:06] <Jonny_> experts*
[11:10:27] <AMcBain> Zip files normally both group files and compress them, tar files just group things. they probably want you to use a zip file to group them but not with compression.
[11:10:40] <btb996> AMcBain: Is it mean that i shouldn't compress the files.
[11:11:30] <AMcBain> nevermind ... just make a tar file out of it and follow the unix instructions.

[11:12:33] <btb996> ok, thanks. But my platform is windows.
[11:13:01] <AMcBain> I assume the separate directions are due to the fact that on Windows it is easier to make a zip file than it is a tar file.
[11:13:28] <AMcBain> Anyways, I've never used this product before. As such, I can only provide limited help on what I can read ... so you aren't really going to get much out of me.

[13:27:00] <ldamwork> harpal, ehm? You call the method on the actual instance, regardles of what your reference is declared as. Since your instance was instantiated as a Sample, then it is Sample.bar() which is called

[13:48:33] <reisi> lock is ReentrantLock and myCondition is a Condition made from the lock using Lock.newCondition();
[13:48:49] <dangertools> reisi: notifyAll() needs the monitor. Is this in a synchronized block? Did other threads call wait() on the object?
[13:49:23] <reisi> dangertools: there's a chance that someone is waiting on the condition when my code block is being run
[13:49:42] *** yclian has quit IRC
[13:49:53] <dangertools> waiting on lock.lock() or waiting using myCondition.wait()?
[13:50:02] <reisi> shit.. i'm supposed to signalAll, not notifyAll

[13:51:07] <reisi> fixing myCondition.notifyAll() -> myCondition.signalAll() fixes this ofc
[13:51:16] <dangertools> wait/notify is a different mechanism. As you already found out, signalAll() is what you want

[15:03:59] <ldamwork> aleksei, jdo is old now, replaced by jpa, which is a merging (simplified soup) of hibernate and jdo and some other stuff. I guess hibernate shortcircuited jdo vendors which is why it's not so widespread
[15:05:25] <ldamwork> another reason could be that afaik there is no free jdo implementations, and companies who pays for persistence probably goes the full entity bean way

[15:10:43] <jottinger> there are free JDO impls, IIRC
[15:10:45] <jottinger> jpox is one
[15:10:45] <corpxicle> why would this happen
[15:11:40] <jottinger> and JDO never really went anywhere because hibernate was too popular to give it room, plus JDO was trying to be more OO than a normal ORM would be
[15:11:48] *** Spike1506 has quit IRC
[15:12:00] <jottinger> developers are fairly normal; they want to use something as simple as possible, and Hibernate was simpler and easier to understand
[15:13:32] <jottinger> and it didn't help that the JDO vendors - the people who benefited the most by widespread adoption - were like "WTF can't you grok this disruptive tech that does things you wouldn't normally expect? I mean, come on, you retards, USE OUR STUFF even though we can't explain it to you"

[15:15:08] <jottinger> the JDO book is almost as good as the javaspaces book: it tells you how to do stuff once you grok the technology but it doesn't do much to, like, get you started even though that's presumably why you'd buy the book in the first place

[15:17:33] <das7002> since the XML file has 14361 values would it be a better idea to get the value from a server that has the data and PHP gives it the requested data?

[16:38:39] <l3ns> isr`, look at the string api
[16:39:09] <isr`> l3ns: yea i think i figured out a way to do it
[16:39:26] <l3ns> good for you =)
[16:39:35] <isr`> using indexOf(ch c, int i) and lastIndexOf(ch c, int i)
[16:39:49] <isr`> er, String ch, whatever

[17:08:50] <dmlloyd> lem: I just am.
[17:09:02] <stork> you must use Integers, kavon.
[17:09:12] <dmlloyd> kavon: primitives aren't objects, so you have to wrap them.
[17:09:13] <hiredman> ints are not Objects
[17:09:31] <dmlloyd> kavon: thus, int[], byte[] etc do not extend Object[].

[17:42:16] <pr3d4t0r> stork: Sure.
[17:42:28] <pr3d4t0r> stork: I just finished writing another booklet last night.
[17:42:30] <lem> Thing`e`, you want tearDown() to teardown what?
[17:42:43] <stork> I was only aware of the one with the Tesla coils
[17:42:46] <pr3d4t0r> stork: So to give you a full status I need to know which one :)
[17:42:47] <stork> and world domination plot
[17:42:48] <pr3d4t0r> stork: Ah.
[17:42:50] <pr3d4t0r> stork: :)
[17:43:05] <stork> which I still haven't gotten round to reading
[17:43:07] <pr3d4t0r> stork: OKi, that one was a 2007 Amazon best-seller, it's sellling so-so, it's a fun project.
[17:43:14] <stork> nice :O
[17:43:18] <pr3d4t0r> stork: Then I have the first App Engine book.
[17:43:24] <pr3d4t0r> ~tell stork about GAE book.
[17:43:24] <javabot> stork, I have no idea what GAE book is.
[17:43:30] <pr3d4t0r> ~tell stork about app engine book.
[17:43:30] <javabot> stork, I have no idea what app engine book is.
[17:43:32] <Thing`e`> well what I need to do is reset an arraylist in the junit test, but the arraylist is in the actual method its testing
[17:43:33] *** agnul has quit IRC
[17:43:34] <pr3d4t0r> Hrm...
[17:43:35] <Thing`e`> is this possible?
[17:44:08] <lem> Thing`e`, that's not possible since tearDown() will be called AFTER the test method
[17:44:25] <lem> Thing`e`, you could call it, but that's out of order
[17:44:49] *** prgrmr has joined ##java
[17:44:49] <Thing`e`> since when I run my tests, it works fine the first time I run the tests
[17:44:53] <lem> Thing`e`, why can't you just add a line to reset it in the testing method?
[17:44:56] <Thing`e`> but the second time I run them, it fails

[17:46:24] <lem> Thing`e`, that is odd
[17:46:37] <Thing`e`> yeah, you'd think if I ran a test once and it worked
[17:46:39] <Thing`e`> it would work always

[17:47:14] <stork> same old, really. Started my CS course at uni Sept last year, just been ploughing on with that.
[17:47:15] <lem> Thing`e`, my advice: add a line to reset the arraylist in the testing method or write a second test method so tearDown() will reset between these these test cases.

[17:49:22] <pr3d4t0r> javabot: AMcBain++

[17:50:18] <Thing`e`> and its set to private in the main class
[17:50:37] <Thing`e`> which makes me think the test won't be allowed to reset it
[17:50:49] <lem> Thing`e`, I guess you were the one who set it to private, so you can change it

[17:51:22] <Thing`e`> I mean I could set it to public, but the test should work around my original code
[17:51:26] <Thing`e`> not the other way round
[17:51:39] <stork> cool.
[17:51:46] <Thing`e`> I just thought the junit test would reset everything every time it was run, but it doesn't :/
[17:51:48] <lem> I think it's better to write a 2nd test case and let tearDown() reset the arrayList.
[17:52:18] <lem> usually it does
[17:52:29] <Thing`e`> I can't tell it to reset the arraylist though

[20:56:18] <vol> So what you're saying is, Sun Microsystems is ruled by tina turner.
[20:56:41] <FriedCPU> hey guys, wondering if anyone got any ideas on how to time a thread?  easiest/best way, down to milliseconds on how long it took it to execute
[20:56:51] *** aTypical has quit IRC
[20:56:56] <vol> System.currentTimeInMillis
[20:57:11] <vol> get the value at the start of run, and at the end of run.
[20:57:15] <vol> Output said value somehow.
[20:57:17] <ernimril> FriedCPU: do you have an OS that give you millisecond precision?
[20:57:57] <ernimril> FriedCPU: the best way is probably to change the source, in a way that vol suggest, you can try profilers if you want, but they tend to change the code you run a lot and your timing may no longer be valid
[20:58:55] <airshipworld> FriedCPU: Which requirement are you trying to solve? Why do you need to know this number ?
[21:00:07] <FriedCPU> would just like to know how long it takes to execute, then i can work on making it faster (quite abit of data analsys inside the thread, so if the thread executes quicker, then i know i have done something right, and when i add things, i can see how much it is slowing it down by)

[21:01:20] <vol> System.out.println("Took us " + (endTime - startTime));
[21:01:25] <airshipworld> FriedCPU: If you are trying to make things faster you don't need to know the time it takes, you need to know hwere the cpu takes most of the cycles. I think you should then really profile your app.
[21:01:33] <vol> ^^
[21:01:38] <vol> A profiler would really help in this case.
[21:02:00] <eidolon> also, the natural baseline question.  "Are you sure you want to use threads to do what you're doing?"
[21:02:18] <ernimril> a profiler _may_ help, but only if you know enough already and method profiling in java have too many problems to be very useful
[21:02:43] <airshipworld> FriedCPU: Netbeans has one build in and there is also one for Eclipse if I remember right. Both free both open source
[21:03:24] <ernimril> when you run method profiling the profiler will _change_ the code you run a lot, so things like method inlining will not happen as much as it will in production, be very careful when you evaluate the profiler output

[21:30:28] <Absolute0> Is java file seeking fast?
[21:30:46] <Absolute0> I have 300 meg files which i want to seek to arbitrary positions.
[21:30:52] <das7002> fatefree:That is what I was using netbeans says can not find symbol
[21:31:07] <ernimril> Absolute0: that depends on how you seek, but yes, it is fast enough
[21:31:28] <cybereal> Absolute0: I have situations where I'm seeking around a 2gb file
[21:31:28] <ernimril> Absolute0: the limiting factor is harddrive (or whatever media/hardware) you have
[21:31:31] <fatefree> you might have to surround it with a try catch block
[21:31:32] <cybereal> and never noticed any slowdown from it at all

[21:32:12] <EruditeHermit> hi, I have an applet that works in appletviewer but when I try to run it in a browser, it is not working. Can anyone help me to get it working in the browser? The HTML I am using is at: http://rafb.net/p/btmLMo14.html
[21:32:19] <cheeser> ~applets
[21:32:19] <javabot> Check the topic, read http://javachannel.net/wiki/pmwiki.php/FAQ/Applets - Basically, we don't support them here.  Try the sun forums at http://tinyurl.com/2q2hog
[21:32:32] <Absolute0> ernimril: cybereal, the reason why i am asking is because i was thinking of placing the entire file into a DB which can be indexed and retrieved in a more elegant way
[21:32:41] <Absolute0> but if a file is faster than i won't need to do this.
[21:32:54] <cybereal> ~~ Absolute0 derby
[21:32:54] <javabot> Absolute0, derby is Apache Derby, an Apache DB subproject, is a relational database implemented entirely in Java and available under the Apache License, Version 2.0. Small, embeddable, client/server. http://db.apache.org/derby
[21:33:27] <ernimril> Absolute0: how could the db be faster? if you store your whole file in a db the cost to access a part of it is (database connection+query time + file seek time)
[21:33:28] <EdwardIII> hrm i was thinking about using sqlite for my little app but maybe i should check out apache derby
[21:33:35] <fatefree> has anyone used squirrel as an sql client? im wondering if theres something out there better than heidisql

[21:33:59] <Absolute0> ernimril: exactly.
[21:34:00] <cybereal> EdwardIII: it's great, and properly indexed it's rather fast (in embedded mode anyway)

[21:36:19] <TryNiX> for a quad tree,  where the nodes are called (topLeft, topRight, bottomLeft, bottomRight), and a node has children if its singleColor is false, would this be an efficient way of conducting a breadth search and printing the colors of the leaf nodes? http://pastebin.com/d116a20fb

[21:36:57] *** eidolon has quit IRC
[21:37:12] <cybereal> Absolute0: I mean use derby instead, it's embedded, you don't have to run a separate server for storing your data and you still get that nice querying capability of an rdbms
[21:37:35] <cybereal> Absolute0: you are talking about deciding between using a flat file and a db, derby's a nice in-between, since it's embedded in your same process as your app
[21:37:45] <Absolute0> oh ok
[21:37:50] <ernimril> TryNiX: why do you think that is a breadth search?
[21:38:01] <Absolute0> but i already have an entire schema and a filled up mysql db
[21:38:08] <vol> TryNiX: Personally, I'd use a queue of some sort, but that's me. Also, this looks a lot like depth first.
[21:38:09] <Absolute0> switching to derby only for files?
[21:38:11] <cybereal> you're the one asking about this
[21:38:22] <cybereal> you need to use your own brain to answer these questions
[21:38:31] <Absolute0> :)
[21:38:43] <Absolute0> fine i'll go turn on my brain processor

[21:39:25] <TryNiX> unless I screwed it up =p but it printed right values
[21:39:45] <TryNiX> vol, hmmm, how would I incorporate a queue for a quad tree?
[21:39:47] <cybereal> Absolute0: they are two entirely different projects with similar goals, but derby tends towards data reliability and hsqldb towards more features
[21:39:56] <Absolute0> oh ok
[21:40:05] *** slonkko has quit IRC
[21:40:06] <cybereal> Absolute0: I've used both over the years and found hsqldb to be less reliable but a little faster especially with poorly defined schemas
[21:40:20] <vol> TryNiX: Probably the same way you would do it for any N sized tree.
[21:40:21] <ernimril> TryNiX: ah, yes you do, you will visit some nodes a lot of times...
[21:40:38] <airshipworld> Absolute0: You speak of indexing and searching, have you thought of Using Lucene ?
[21:40:48] <airshipworld> It's build to search
[21:40:55] <ernimril> TryNiX: so depending on your definition of effiecient it may or may not be, it will not be the fastest one, it will use very little memory

[21:42:07] <EdwardIII> cybereal: cool
[21:42:12] <TryNiX> I read about breadth-search on wikipedia, but my dull brain couldn't comprehend it to be honest =p
[21:42:17] <ernimril> TryNiX: keep a queue of nodes to visit
[21:42:19] <TryNiX> the example code they posted there that is
[21:42:23] <Absolute0> airshipworld: no so much as searching but seeking :)
[21:42:24] <ernimril> TryNiX: start by adding the root node
[21:42:39] <vol> TryNiX: Do you understand the difference between breadth-first and depth-first?
[21:42:55] <ernimril> TryNiX: then you pick one node from the queue and put all child nodes at the end of the queue

Normally I'd read the line, trim it, and cast it as the type I want. readLine is deprecated for datainputstream though. They want you to use readInt, etc. Is there a way to make this generic friendly?
[22:08:26] <cheeser> rhsanborn: no, it's not a generics thing at all.

[22:47:14] <isr`> i suppose i could use a mutable object.
[22:47:27] <cybereal> One example of a solution, instead of making an anonymous class for that Runnable, define a real class that implements Runnable and also has a getter for that GUI root node I mentioned, then in the run() method in that class, it can call that GUI.whatever() call, set a field to the return value, and be accessible later.  Instantiate that class and pass it to invokeLater and then access the class's getter...
[22:47:36] <isr`> like someClass.setGui(GUI.createAndShowGUI());
[22:48:03] <isr`> thats a good idea too
[22:48:06] <isr`> thanks for the tip dude
[22:48:33] <cybereal> call it Application, give it a start() method that does the invokeLater stuff itself, and then from your main POV it's entirely encapsulated the GUI part of your app into one conveniently creatable/usable class
[22:49:08] <cybereal> anyway I'm sure there are numerous ways to go about this that's just what comes to mind

[22:54:11] <vol> (and to a very small extent a bit like here)
[22:54:34] <cybereal> vol: yes, we have similar such legacy nonsense in my codebase... it's been around for a while
[22:54:52] <cybereal> it's really obvious that the original developers were C guys thrown into a java world unwillingly
[22:55:16] <cybereal> java's cruel to C or C++ programmers because it looks similar, but really ... not so much actual similarity :)
[22:55:54] <cybereal> Sometimes I think programmers may actually be weirder than birds, as unlikely as that sounds.
[22:55:58] <vol> EnderMB: Anyway, ask them to find a decent sized, respected java project that flaunts sun's coding convention. Tell them when they do that you'll change your mind.
[22:56:05] <EnderMB> Right. Well, one of the developers that is supposed to be mentoring me has complained about me using naming conventions like "int i" for temporary variables, even though the Sun documentation is right and others have different opinions on the subject. Do I call him on it or use some other convention?
[22:56:33] <cybereal> EnderMB: 'i' doesn't mean anything, is he suggesting you use a longer word?
[22:56:39] <reverend> what variable name is he suggesting?
[22:56:46] *** durka42 has joined ##java
[22:56:48] <vol> EnderMB: That depends. int i as in "for(int i = 0; i < foo; i++)" ?
[22:57:05] <vol> it's somewhat reasonable in that I'm not the first person to transpose i and j in my loops.
[22:57:13] <cybereal> I never use single letter variables anymore, far too many stupid errors caused by that.
[22:57:17] <EnderMB> If I remember he uses underscores to begin with and the same variable as one he's using in a getter, if that makes sense
[22:57:40] <EnderMB> So if he were making a getter for a car variable he'd use _car.
[22:57:43] <vol> I do that as well
[22:57:53] <cybereal> I've seen that convention, kinda pointless but it helps some people immediately see that it's a field
[22:57:53] <EnderMB> Is that not more confusing?
[22:58:08] <cybereal> it makes using code generation tools less appealing :) but not confusing
[22:58:10] <vol> EnderMB: again, it depends :P
[22:58:12] <ldamwork> EnderMB, that sounds even more stuped; home made convention instead of defacto convention. It would be acceptable if a meaningfull name was to be used
[22:58:22] <vol> do you mean the member var starts with _ ?
[22:58:37] <vol> or do you mean something like "void setCar(int _car) { car = _car; }"
[22:58:44] *** The_Birdman has quit IRC
[22:58:48] <ldamwork> afaik, suns convention disapproves names starting with underscore
[22:59:00] <EnderMB> Yes, the latter
[22:59:04] *** The_Birdman has joined ##java
[22:59:15] <cybereal> so it's the parameter to the setter
[22:59:27] <EnderMB> Yes
[22:59:29] <cybereal> avoiding name shadowing is a "Good Thing (tm)"
[22:59:30] <vol> ok, you said getter, so that confused me.
[22:59:38] <indeterminatus> void setCar(int car) { this.car = car; }
[22:59:46] <cybereal> using underscore to start a variable name is generally not great
[22:59:49] <ldamwork> "Variable names should not start with underscore _ or dollar sign $ characters, even though both are allowed."  -> http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html#367
[22:59:55] *** musically_ut has quit IRC
[23:00:30] *** jZep has left ##java
[23:00:32] <cybereal> starting a variable name with a symbol is indicative of some language level meaning beyond just being a name
[23:00:42] <vol> Hmm, I do that, I guess I should change :)
[23:00:56] <cybereal> so avoiding it is a best practice
[23:01:15] <EnderMB> Although in that same part it claims that temporary variables like int i are okay.
[23:01:36] <vol> for throwaway variables, yes.
[23:01:39] <cybereal> I'm one of those jerks who likes wordy names, so for parameters I'll do something like setCar(int carParam) { car = carParam; }  unless something more specific makes sense when "speaking" the terms
[23:01:50] <indeterminatus> I don't even accept those, but I'm a bit strict in that respect.
[23:01:55] <cheeser> cybereal: yeah.  i never shadow my fields with variables
[23:01:56] <cybereal> EnderMB: int i is a special case because it's easy to mistaken it for other letters
[23:02:35] <indeterminatus> There is no such thing as "throwaway variables", or "temporary variables".
[23:02:57] *** rollins has quit IRC
[23:03:03] <cybereal> EnderMB: and besides, it's nice to read code that you don't have to do as much work to figure out its intention, using the word index instead of i or even idx, I find results in code that you can grok faster upon your first read
[23:03:42] <EnderMB> So in the case of a setter which is the ideal convention? at the moment I just use i for int, c for char, etc.
[23:03:56] *** UT2K3 has quit IRC
[23:04:02] <vol> indeterminatus: I'll bang out "for(int i = 0; i < foo.length; i++) { foo[i] = myVal++; }"
[23:04:05] *** beol has quit IRC
[23:04:10] <vol> I consider that entirely reasonable.
[23:04:12] <cybereal> you should use names that describe the use/purpose of the value not the type, java maintains what type it is for you
[23:04:29] <indeterminatus> What cybereal said, can't stress that point enough.
[23:04:30] <vol> I COULD type index for all of these, but that's a slowdown, and I understand intuitively what "i" means
[23:04:38] <cybereal> though sometimes those recommendations blend, especially when the only purpose of a variable is to hold a type specific representation of another one
[23:05:16] <ldamwork> old for() style can be replaced with for each and thus you dont need a 'tmp' variable. If you DO need it, it would have a purpose and can thus be named reasonably, like 'row', or 'line'...
[23:05:20] <cybereal> if you think typing a few more letters is a slowdown then I imagine you've never worked on large projects (or just haven't been smart enough to figure out why they are hard)
[23:05:56] <cybereal> i|j|l
[23:06:34] <vol> for each is great unless you actually need the index value, or what you're iterating over doesn't have an iterator.
[23:07:01] <ldamwork> vol, exactly. And if you DO need it, then you have a purpose for it, and you can name it in that respect...
[23:07:11] *** dmlloyd has quit IRC
[23:07:39] <vol> ldamwork: In that case I'm just a terrible, lazy programmer, more suited to perl.
[23:08:22] <reverend> laziness is a virtue for a programmer, as long as it's productive laziness :)
[23:08:24] <ldamwork> :) (well, i do use i,j in loops as long as the scope level is not more than just a few lines (<~10))
[23:08:51] <kavon> i use d, b, p, and q to annoy the hell out of people

[23:09:07] *** The_Birdman has quit IRC
[23:09:14] <indeterminatus> vol: I don't want to argue about 'i' as name for index variables. I don't like one-lettered names or any other kind of non-speaking names ('temp' being the worst of that kind that comes to my mind). But it always takes me a while to decipher statements with side effects, like "foo[i] = myVal++;" -- I always like to keep side-effects out of assignments, thus making it "foo[i] = myVal; ++myVal;" which is much easier on the eyes, methinks
[23:09:33] *** DragonLord- has quit IRC
[23:09:44] *** Wicked has quit IRC
[23:09:45] <ldamwork> i suggest that we should use i,ii,iii,iiii,iiiii,... instead. It is so much easier to identify scopelevel by the count of i's
[23:09:54] <EnderMB> Would you ever consider it good practice to give both variables (global and local?) the same name, even though they're different variables?
[23:09:57] <indeterminatus> That's an awesome idea!
[23:09:59] <vol> indeterminatus: that was just a sample. It could well be "foo[i] = myObj.getSomethingSpecific(i);"
[23:10:11] *** resmo has quit IRC
[23:10:16] <vol> EnderMB: define "global"
[23:10:28] <ldamwork> a[iii][iiii]=b[i][ii]; :)
[23:10:36] <EnderMB> i.e. this website: http://mindprod.com/jgloss/setter.html
[23:10:41] <vol> ldamwork: you're doing it wrong. if you're going to go this route, just use roman numerals.
[23:10:52] <EnderMB> Like how they've used "this.height = height" inside the setter
[23:10:57] <kavon> ldamwork: good idea but it would fail once you have to sit there and poke the letter i while counting out loud to make sure you don't mess it up
[23:10:58] <indeterminatus> ldamwork: a[++ii][iii++] = b[++ii][++ii]; :) :P
[23:11:02] <vol> Ah, that's not global, that's a member variable.
[23:11:08] <kavon> ldamwork: better one is a, b, c, d, e
[23:11:10] <kavon> etc
[23:11:39] <EnderMB> Ah, so member variables and local variables?
[23:12:04] <vol> EnderMB: in that example, you're setting the member variable for that object to be the variable you've just passed in
[23:12:38] <vol> iirc this is an acceptable naming scheme
[23:12:49] *** charzero has quit IRC
[23:13:24] <vol> for example, you may have a constructor like Box(int width, int height) { this.width = width; this.height = height; } Your IDE will generally color these differently, so you can pick up a mistake (forgetting this, for example) more easily.

[23:14:13] <cheeser> vol: better yet, don't use variable names that shadow field names.  then there's 0 ambiguity
[23:14:28] <EnderMB> ldamwork: NetBeans doesn't.
[23:14:35] <ldamwork> EnderMB, i said a proper IDE
[23:15:03] <EnderMB> It's my fault for working at a university...
[23:15:12] <cheeser> netbeans is a proper IDE
[23:15:25] <ldamwork> cheeser, room for improvement then...
[23:15:56] <indeterminatus> EnderMB: If you want to read up on the topic, "Code Complete" is a pretty good source to get you started
[23:15:58] <ldamwork> idea reports 'variable is assigned to itself',
[23:16:06] <cheeser> probably.  but at least it's no eclipse.  *shudder8
[23:16:12] <vol> ldamwork: that's what I said.

[23:23:04] <EnderMB> Oh yeah, one more question. I'm reading through UML Distilled and it mentions UML modelling programs that can generate UML Class Diagrams purely from code, but I've only been able to find one for Java. Are these kind of things any good?

[23:25:23] <EnderMB> I tried to use the UML plugin and it killed NetBeans, so never again.
[23:25:35] <aleksei> and is easier than trying to understand a system just by looking at its code
[23:25:38] <indeterminatus> I didn't find a truly usable (free) tool, and I haven't looked in a while

[23:31:50] <reverend> uml sucks
[23:31:56] <reverend> well, that's not true
[23:31:59] <EnderMB> I typically just use a pen and paper/whiteboard to describe things, but I've been told to provide a UML diagram so that my mentor doesn't have to "read through the code".
[23:32:03] <reverend> it's a great way to represent a disposable idea
[23:32:12] <cybereal> as I said, snippets in documentation
[23:32:17] <reverend> or at least, something with a short lifespan
[23:32:26] <reverend> or extremely high level
[23:32:28] <cybereal> I'll use it to make dumb people ask fewer questions about what I'm changing in a portion of an object model, for example, in change specifications
[23:32:37] <aleksei> I think it's good to use at a general level.. don't document even the smalles class in your source
[23:32:45] <vol> Oh god UML : (
[23:32:53] <cybereal> I never use it to design the actual code or anything like that though
[23:33:07] <indeterminatus> Yeah, what aleksei said. Great to give an overview, and many people "understand" it (due to its standardization).
[23:33:13] <reverend> at my current gig we're forced to include sequence, class and system diagrams in our LLDs
[23:33:17] <reverend> it's pointless
[23:33:26] <EnderMB> Ouch.
[23:33:41] <reverend> none of those models are accurate by the time implementation is underway
