Waking up a sleeping thread - interrupt() versus “splitting” the sleep into multiple sleeps

Question

Answer 1

You call interrupt() on the thread that's sleeping and it will throw an InterruptedException which you handle in your catch block. Then you have your new interval and you can loop around and go back to sleep. If you catch and handle the InterruptedException nothing further happens.

Let me provide a couple of links of examples of creating and interrupting threads, as from your comments you seem to be missing some important ideas. Please review these carefully and then you should understand the standard way to do what you are asking for.
