l wait是Object类的方法,它的作用是拥有互斥锁的线程放弃锁的使用权,进入wait池进行等待,那么互斥锁就有可能被其他线程获得以执行其他任务。 l notify也是Object类的方法,它的作用是从wait池中唤醒一条正在等待的线程进入就绪状态,被唤醒的这条线程就很可能重新获得cup和互斥锁来完成它的任务。 l notifyAll和Notify...

A class that will wait for other threads to invoke notify methods to complete it’s processing. Notice that Waiter thread is owning monitor on Message object using synchronized block. 这个类则等待其他线程去调用notify方法去完成所有代码的执行。注意waiter线程(等待被唤醒的线程)自己使用了messge对象作为...
