Q1: 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?

ANS:A - After thread A is notified, or after two seconds.

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.
