Assume the following method is properly synchronized and called from a thread A on an object B:
wait(2000);
After calling this method, when will the thread A become a candidate to get another turn at the CPU?
Note
Option A. Either of the two events (notification or wait time expiration) will make the thread become a candidate for running again.
Option B. is incorrect because a waiting thread will not return to runnable when the lock is released, unless a notification occurs.
Option C. is incorrect because the thread will become a candidate immediately after notification, not two seconds afterwards.
Option D. is also incorrect because a thread will not come out of a waiting pool just because a lock has been released.
