threads

[srilatha rao]

If a parent thread invokes join method on a child thread, then parent thread will go into the blocked-for-join-completion state.
If that child thread sleeps for some time in that execution, Will the parent thread start running before the completion of child thread.

please explain...

Thanks in advance

NO. Since the parent Thread is sleeping it cannot wake up just until child Thread has finished his work or it has been interrupted.
