Ahh. Yes, that does work. I haven't gotten to "this" in my book yet. I see that it stops printing "Action" without stopping the program. I can see how that's probably a better option in most cases. Thanks a lot.

O.K. I finally got it. That definitely took longer than it should have.

I was getting an error message with timer.cancel(); , but System.exit(0); worked straight off. I've put the final product below for any rookies (like me) that might look for it.

Thanks for the help.

import java.util.Timer; import java.util.TimerTask; public class Race { public static void main( String[] args ) { int delay = 1000; // delay for 1 sec. int period = 1000; // repeat every sec. Timer timer = new Timer(); timer.scheduleAtFixedRate(new TimerTask() { int count = 0; public void run() { System.out.println( "Action" ); count ++; if(count == 5) System.exit(0); } }, delay, period); } }

Thanks for your reply

I'm not having much success with that. The code below causes "Action to be print 5 times immediately, every second (after the 1 second delay). I believe that the 1 second delay in the timer method does not prevent the computer from running through the for loop quickly. So, 5 timers are created in less than a second and they all activate after the one second delay. Also, if the timer.cancel(); is un-commented, the program prints nothing because it ends before the one second delay has run it's course. I've tried a slightly different version of this with the timer.cancel(); placed within an if( count == 4) loop. It also prints nothing.

Perhaps the timer method will not work the way I want it to. Maybe, I need a different method. Any thoughts?

Timer timer = new Timer(); // This causes Action to by printed 5 times every second timer.scheduleAtFixedRate(new TimerTask() { public void run() { for(int count = 0; count < 5; count ++ ) { System.out.println( "Action" ); } } }, delay, period); //timer.cancel(); } }

Hi,

This is my first post here, so please bear with me.

I want to make my simple program print "Action" 5 times and then stop. The code below will print "Action" once per second forever. If I un-comment the timer.cancel(); it stops before it even prints once. I've tried putting the timer inside a for loop and inside a while loop, but can't make them work.

What am I missing?

Thanks in advance.
