Question: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?
A After thread A is notified, or after two seconds.
B After the lock on B is released, or after two seconds.
C Two seconds after thread A is notified.
D Two seconds after lock B is released.
+ ExplanationOption 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.
