What is the difference between wait () notify () and notifyAll ()?

The wait() method causes the current thread to wait until another thread invokes the notify() or notifyAll() methods for that object.

What is stop () method in Java?

Whenever we want to stop a thread from running state by calling stop() method of Thread class in Java. This method stops the execution of a running thread and removes it from the waiting threads pool and garbage collected. A thread will also move to the dead state automatically when it reaches the end of its method.

Why wait is called from synchronized block?

Calling notify() or notifyAll() methods issues a notification to a single or multiple threads that a condition has changed and once the notification thread leaves the synchronized block, all the threads which are waiting for fight for object lock on which they are waiting and lucky thread returns from wait() method …
