I'm doing a CS assignment that monitors network traffic, or slowness. I have this small java app that downloads a webpage and prints out the time that it took to do it. I have this loop running forever. However it would be really nice if I could get it to only load the page once a minute. How can I make the application pause for a minute?

Thanks.

try{java.lang.Thread.currentThread().sleep(60000)}
catch(Exception e){}

That should sleep the current thread for 60,000 milliseconds (or 60 seconds).

An easier way would be to use an NSTimer and have it fire every minute:

NSTimer timer = new NSTimer(60,this,new NSSelector("methodName",new Class[]{this.getClass()}),this,true);
NSRunLoop.currentRunLoop().addTimerForMode(timer,N SRunLoop.DefaultRunLoopMode);

The former locks your app for a minute, the later calls a method every minute.

OK thanks but I'm not using threads. I like the first way better since I can just stick it in there, but how would I do it if my app isn't threaded?

nevermind, i just removed CurrentThread and it works perfectly. Thanks!

Oh sorry, there was suppose to be parenthesis at the end of current thread... but u said it worked when getting rid of currentThread? I didn't think you could call that method from a stati context. Oh well.

Atleast it works now,

Thread.sleep() always refers to the current thread. When you call Thread.currentThread() to get a thread reference, you are STILL calling a static method even though you are invoking it on an object.

BTW, whether you know it or not, EVERY java program is threaded by definition. main() is invoked by the main thread, and any other thread you create (or if you open an AWT window or invoke a method which creates a thread) will make your program multi-threaded.

Forget this post. Don't try to edit a post with code in it! UBB could sure be smarter...

Why not do the same using Java libraries?

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
import java.util.Timer;

class Timeable implements TimerTask

{
<font color = brown>//do your every-minute task.</font>
}

public static void main(String [] argv)
{
<font color = brown>// create a timer</font>
Timer timer = new Timer();
<font color = brown>// schedule an instance of this class</font>
<font color = brown>// to run every minute, with no initial delay</font>
timer.schedule(new Timeable(), <font color = blue>0</font>, <font color = blue>60000</font>);
}
}

That previous class should extend TimerTask, not implement it. Sorry.
