<0> I have a loop in which I create a new Thread (and start it) upon at the end of each iteration. The trouble is, I do not want to start to start the next iteration of the for-loop until the thread is completed. Any ideas please? (Java 1.5)
<1> use signaling (wait/notify)
<1> or what the new 1.5 concurrent package offers you
<0> _kmh_: are you talking about the join thing?
<1> no
<1> i'm talking about wait/notify as written
<2> join sounds good. something wrong with that?
<2> tiggger?
<0> sorry, I'm reading up on wait/notify
<1> http://www.javaworld.com/javaworld/jw-10-1998/jw-10-toolbox.html
<0> I've read about this before and not gotten anywhere, hopefully I will this time =]
<2> "Waits for this thread to die." sounds good.
<0> thanks
<2> tiggger: have you tried Thread.join()?
<0> ahh, thanks I'll read that
<1> actually join is a special case of wait/notify
<0> Clackwell: I did try it once but I couldn't get it to work actually
<0> I see
<1> make sure you call join of the right object if you go that route
<2> tiggger: http://rifers.org/paste/show/1496
<2> test cases++
<2> bye
<0> Clackwell: thanks , i'll take a look
<0> bye
<1> tiggger : join is easier for your case than to setup your own signaling
<0> _kmh_: thanks, i'll try fiddling around with this example and seeing what I come up with
<0> while I'm here, how easy is it to use/setup a debugger? I've been coding java for a few years now, and have never used a debugger. My programmes are getting quite big now, and simple trace statements don't appear to be that easy to follow anymore.
<0> and can you recomment anything. I've heard of jdb
<1> the easiest is to use an integrated debugger from an ide
<3> are you're cl***es getting huge?
<3> if so design them better, else carry on without a debugger
<0> they are quite big, and honestly could do with being redesigned a bit, but I've no time for that just now. I'm not desperate for a debugger, just curious. Plus I think employers are interested in people that use debuggers.
<0> perhaps I'll forkout for the full version of Jcreator---I think it has a debugger
<1> tiggger : netbeans, eclipse, jbuilder foundation all come with an integrated debugger (and are free)
<0> _kmh_: thanks, maybe i'll switch to eclipse, I hear a lot about it
<0> it would be nice just to see the values of some variables at runtime, rather than having to quit the program, insert some trace statements and recompile/execute
<4> sal
<4> care ma ajuta si pe mine cu ceva
<4> ?
<4> pls
<0> thanks for the advice _kmh_
<5> after i have installed JDK 6 Beta 2 AMD 64, i go into Command Prompt and type javac HelloWorldApp.java (in the created directory c:\java with the HelloWorldApp.java file in) but windows does not recognize the commad. can anyone help me.
<6> is it in your path?
<5> yes
<6> javac -v gives you what
<5> ill try
<5> the same not recognized.
<6> apparently it's not in your path after all
<6> for whatever reason
<5> when i do "dir" its in there
<6> where? c:\java?
<5> yes.
<6> erm
<5> im running XP x64
<6> javac should be in c:\java\bin then
<5> no im entering javac as a command in the command prompt
<5> c:\java just has my hello world app in it.
<6> Where, then, is javac
<5> oh right i should run it from the directory when it is installed?
<6> no
<6> but the directory that has javac should be in your path
<5> ok ill go try 2 secs.
<5> same..
<5> can you run me through exactly what i have to do..
<2> Rip_UK: http://javafaq.mine.nu/lookup?67
<5> ill have a look through that Clackwell thanks. 2 mins.
<2> Rip_UK: when changing env vars in control panel/system, make sure to open a new instance of cmd.exe via start/run...
<2> (anything else might not work correctly)
<5> yes i was going to start.. run.. cmd
<2> Rip_UK: pastebin.com the output of this: echo %PATH%
<5> ?
<6> Rip_UK: open a command shell, then run "echo %PATH%" -- without the quotes
<2> copy and paste to that site...then post url here
<6> and then tell us what it says
<5> ok
<5> c:\windows\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
<5> is that right?
<2> Rip_UK: where is the java bit in that?
<5> im not sure what im doing here
<2> Rip_UK: go to control panel again and check the environment variables again.
<2> Rip_UK: why are you unsure? you are running a 64 bit operating system, you should know a bit about operating systems.
<5> where do i find the environment variables
<2> Rip_UK: see above link, it explains
<5> ok
<2> [19:48] <6> is it in your path? [19:48] <5> yes
<5> sorry i thought he meant something else.
<5> im new to this ;)
<6> why the **** are you running a 64-bit machine?
<5> lol
<5> why not
<5> NZXT Nemesis (White)
<5> Digimate 17" TFT Monitor (White)
<5> Msi K8n Diamond Sli
<5> AMD 64 4400+ X2 With AS5

<2> dude...
<5> sorry.
<7> lofl
<2> kick*** machine, laughable monitor, screams for a knowledgable operator
<5> ;)
<5> i cant find the environmental variables in control panel , system
<2> Rip_UK: well...keep looking
<2> i have never seen xp64, so no clue if it looks the same.
<5> not in here i dont think
<6> somewhere the god of pebcak is smiling down upon you
<6> "See that guy? He's my poster child."
<7> right click MyComputer ->Properties->Advanced
<5> no advanced they're
<7> sad to know that
<6> "no advanced they're"?
<6> Oh my
<7> lol
<5> advanced tab
<5> hehe
<5> ****.
<8> no advanced they are? are you trying to be yoda or something?
<5> there it is
<5> lol
<6> I think you've just done absolutely horrible things to the english language.
<5> took me a while.
<7> scots usually do that
<6> on behalf of the engrish lanjuage I smite thee
<5> if there is no path in user variables do I add it in?
<7> if you set it system then all users get it
<7> you got one of those exploding dells didn't you?
<5> lol saw them in the paper
<6> sabre: we can only hope
<6> *boom* *#java's pain goes away*
<7> http://www.boingboing.net/2006/07/28/dude_your_dell_just_.html
<5> ok i have just added C:\Program Files (x86)\Java\jdk1.5.0_08\bin to the right of the text in Path in System Variables
<7> that's what happens when you don't set your path correctly
<6> hahaha
<7> you sure? :)
<5> hmm
<7> Rip_UK you might want to give the java tutorial a look
<6> you may want to give "computers for dummies" a look too
<5> oi
<7> hehe
<5> thats where i was looking the java tutorial
<5> yay
<5> thanks guys.
<5> cya
<9> Hi, im kind of new at this. How can I iterate a Hashtable?
<10> Get the keys, walk through them.
<9> the thing is, i don't have the keys, that's why i need to iterate them
<10> for (Object key : tehTable.keys()) { Object thing = tehTable.get(key); }
