What is the best way to call repaint() at regular intervals in my Java2D program?

Question

I'm looking to call repaint() in my Java2D simulator at regular intervals.

What would be the best way to do this? Should I start another thread and have a loop that keeps track of currentTimeMillis()? Or is there a better way?

Does your simulator need to 'simulate as fast as possible' or 'simulate at a fixed rate'? The answer may change how you structure this. — Tom Neyland, Oct 19 '09 at 04:47

Use a Timer. If its a Swing application use a Swing Timer. If its AWT then use TimerTask.

Swing's `Timer` works fine for AWT. With `java.util.Timer` you would need to do the `invokeLater` yourself. – Tom Hawtin - tackline Oct 19 '09 at 14:45
