If you want clarification, it would be a good idea to tell us which three you think are correct. Then someone can tell you about which one you are mistaken and why. [ April 30, 2002: Message edited by: Dave Winn ]
i know that the notify() and the notifyAll() just let the thread in the waiting pool to become the Seeking Lock state,so C and D is definitly correct. how about the choice E? i think it will only cause the thread eligible to execute but not directly stop a thread.am i right?
