without first checking. A typical example of the Set method is the Unlock () method in the lock class. A thread holding a lock is always able to unlock successfully without checking that the lock is in an unlocked state.The program flow of the set method is usually as follows: Set internal state Notifies the waiting thread Here is an example of the Unlock () method: Public class lock{ Privatebooleanfalse; Public synchronized void unlock () { false; Notify (
