Helps coordinate producer-consumer tasks.
Must be inside synchronized blocks.
Quick Answer
Inter-thread communication uses wait(), notify(), notifyAll() on a shared object. wait() releases the lock and puts the thread to sleep until notified. notify() wakes one waiting thread. notifyAll() wakes all. Must be called within a synchronized block on the same object. Used for producer-consumer pattern. Modern code uses BlockingQueue instead - much simpler and less error-prone.
