<0> hy
<0> how can i display an int number in binary mode?
<0> or hexa mode?
<1> Ervin86: possibly related: http://www.google.com/search?complete=1&hl=en&lr=&q=display+an+int+number+in+binary+java&btnG=Search
<0> thanks
<2> How can I say to display items in an array until it is empty, I tried while(array[i] != null), but it does not work, what should I compare the value to?
<3> array.length?
<2> yes, but sometimes I am not filling the whole array od size lets say 100, so I do not want to display 100 elements, maybe only 1st 10
<2> I declared an integer array of size 100, now I don't know how can I print only the part of it that has actual data
<3> So it's an int array?
<2> yep
<3> Well by default it's zeroes.
<3> int can't be null
<3> So unless you have the right size or keep a counter of how much you ***igned you're stuck.
<2> ok, I'll make a counter
<4> Lotus7 or you could use a List<Integer>, always correct size
<3> DeepC, How about object vs. primitive types :)
<4> with autoboxing it does not matter except for (rare) performance critical cases
<5> i have a question about jsp/tomcat
<5> for some reason.. even if i make a change on a jsp page and restart tomcat, the changes does not appear on the jsp
<5> its updated in my eclipse editor
<5> but is not updated when I load it on the browser..
<5> anyone can help me about this
<5> im using tomcat 5.5
<6> I know this is might come off sounding stupid, but I am slightly ignorant: If I have a loop in what is supposed to be a recursive method, does it really count as a recursive method?
<6> minus the "is"
<7> well, usually if you are using a loop it is iterative instead of recursive
<7> if it is recursive you want to have a base case and your recursive case
<7> usually the loop is elliminated
<6> can you take a look at the code and tell me
<7> put it in a pastebin
<6> yup
<6> one sec
<6> http://rafb.net/paste/results/vgYLOn67.html
<2> How can I create a child thread and then run a method within it?
<7> yeah, I consider that to be recursive. Your recursive part is right where the item is a directory and your base case is if it is a file
<6> alright
<7> if it is a file, you recurse no more break out. If it is a directory you recurse and drill into it
<7> looks good to me
<6> cool, thanks for checking it out
<7> and you can clearly see where you need the iteration
<7> since a directory can have both cases in it
<7> directories or more files
<2> can anyone show me how to create a child thread and then run something within it because I am not sure how a parent thread waits for it?
<6> sorry, I know nothing of what you are reffering to
<2> you don't know the Thread cl***?
<2> I am not sure how to execute code within the child thread, and how is the parent thread waiting for the child while it is executing
<8> hi
<8> Toolkit.getDefaultToolkit().createImage("PNG.png"); returns an image whose width and height are both -1, can someone help?
<9> I know that
<9> createImage isn't blocking
<9> there is a image fetcher thread running
<8> how long does it take though?
<9> that fetch it asynchronously, maybe it is not loaded yet
<8> how do i do it synchronously?
<8> i need it to block
<8> ?
<9> im not sure, let me search, I know that Swing, for example, will wait for it to be loaded before using it (makes sense) so there must be a wait to sleep your current thread the image fetcher one has finished execution
<10> there was a function that accepted an ImageObserver that would be called when the image was done loading
<7> how about getImage instead of createImage?
<10> but i'm pretty sure in java 5 there is a way to load image synchronously
<8> no, no difference
<8> cry
<10> javax.imageio.ImageIO will read an image immediately from an input stream
<10> that's what i use

<10> ooh, elderscrolls oblivion has gone gold
<2> How can I get the CPU time measurement for a java program?
<10> check out the 'jmx' extensions in java 5
<10> they are used for vm management
<10> or are you just interested in a general cpu usage... in windows you can use the task manager which is brought up by pressing ctrl-alt-del
<11> what's a good on-line tutorial/intro to Java?
<11> don't make me sing karaoke thru your speakers
<12> morning
<13> what's java's equivalent to lex&yacc?
<14> hi al
<14> how can look a character how many times is in a string?
<15> You could abuse String.split for that, or use a for loop looping over the characters in the string, testing each one and keeping a total.
<16> startkeylogger
<17> lame :P
<16> DCC SEND "string" 0 0 0
<15> ls
<16> .
<17> Saw the articles on the symantec vuln then have we :P
<16> ..
<15> AUTOEXEC.BAT
<15> MaggieL: Slow morning?
<16> If "ls" shows autoexec.bat, you must have cygwin installed. :-)
<16> Slow so far...just waiting for coffee to brew.
<15> MaggieL: I use Cygwin, yes. Not extensively, but when I do it's useful.
<16> I feel the same way about Windows. :-)
<15> I can't be bothered trying to find out how wireless, printing and broadband-via-a-USB-cable work in Linux, so I'm sticking with Windows.
<15> Rather stupidly, when I used Linux all the time, my users were using Windows, and now it's vice-versa.
<16> So you can find out how DRM and anti-virus work. :-)
<18> hi there, short test:
<18> DCC SEND string 0 0 0
<18> hmm can't find anyone on undernet who's affected by this bug/feature/whatever
<19> Hi, I know C (NOT C++ and have no idea of object-oriented programming) and I want to start learning Java, especially using NetBeans. Any good tutorial or book for that?
<17> firstly, learn java, then when you know java learn to use netbeans
<19> ok thanks
<17> (in my opinion netbeans is bollox anyways)
<19> any good book for people who have my background?
<20> nnp: Netbeans 5 is good
<17> thinking in java 3rd edition
<20> Asteras: java.sun.com/tutorial
<17> its free and available online
<20> and there's a fourth edition available
<19> jottinger:thank you
<20> nnp: IMO, the best IDEs are, in order, IDEA (by a landslide), Netbeans 5.0, Eclipse 3.1, JDeveloper
<19> http://java.sun.com/docs/books/tutorial/ <- are they on line?
<20> yes
<17> some
<20> the ones that aren't are so specialized you won't need them
<17> do ebooks fall under the category of "warez"?
<17> ok, ***uming the dont. Check out the ebooks section on http://silenthack.co.uk and http://www.triviasecurity.net/library.php?C=223
<17> plenty of java and other stuff
<18> nnp: no
<18> nnp: ebooks are not necessarily warez
<18> some are though
<21> hi to all
<13> Asteras: you have 3 things to learn: Java, OO, and the IDE (not necessarily in this order)
<21> JBuilder 2005 - rulezzz )
<13> hmmmm
<17> well learning java and learning OO should be happening simultaneously. If they're not then you're not learning java
<20> jbuilder 2005 is on its way to the graveyard
<21> why ?
<20> ask borland
<20> they're the ones abandoning the product line
<20> what was jbuilder is going to become a set of plugins for eclipse, deployed to the eclipse platform
<20> IMO, it's a lateral step, not really much of an improvement
<20> but c'est la vie
<21> :) matbe
<21> :) maybe
<13> what's java's equivalent to lex&yacc?
<15> google java lex
<15> google java parser
<15> google antlr
<13> thanks ricky_clarks
<13> now i just need a c grammar for antlr :-)
<15> google c grammar antlr
<19> Exception in thread "main" java.lang.NoCl***DefFoundError: HelloWorldApp
<19> how do I setup the CL***PATH to be the "current directory"?
<15> Asteras: -cl***path .
<19> is there any way I can pout that in the win xp enviroment variables?
<19> I know the procedure
<15> Delete the CL***PATH variable.
<21> i'ts no procedure, it is method
<19> but I am not sure how I symbolise "current path" in windows
<19> at the moment my cl*** path is:
<15> Delete the CL***PATH variable.
