on page 510 k&B,
It says that you can't be certain that how long a thread will actually run before it gets put to sleep.

I want to know whether the thread will sleep with each iteration or can it skip the sleep method and will sleep arbitrarily.

Pls. let me know.

It will sleep for at least 5 seconds during each of three iterations. Provided another thread does not interrupt the thread when its sleeping.
