Is there a way in java to do nothing in a program say for thirty milliseconds without using Threads.sleep() method call. I looked up the documentation but could not find anything.

Thanks,

you could get the current time, enter a loop that just checks the time against 30 millis from now.

But why not use threads?

There's no reason to not just use the static method in Thread.

Code:
void pause(long millis) {
	try {
		Thread.sleep(millis);
	} catch (InterruptedException e) {
	}
}

	...

	pause(30);

You are using threads in every Java program you write, since even if your program has only a single thread of control, it is by definition in a thread which is separate from the event system, the garbage collector, etc.

Thanks a lot guys !
You have helped me a great deal.

Is the equivalent way of sleeping threads in Obj C to

[myThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:.03]];

? This seems reasonable but it also seems a bit heavier than it needs to be. Do you also have to put in an autorelease command, e.g.,

[myThread sleepUntilDate:[[NSDate dateWithTimeIntervalSinceNow:.03] autorelease]];

?

A quick note of caution:
if you are using the Thread.sleep() method you should be aware that the time the thread will sleep for will be _at least_ the time you specify, but will quite likely be more than that so you cannot depend on sleep for critical timing.

That's why Java isn't used in real time systems -yet
