waiter1 waiter thread got notified at time:1356318918120 waiter1 processed: notifier Notifier work done waiter waiter thread got notified at time:1356318918120 waiter processed: notifier Notifier work done 因为notifyAll()方法会把两个waiter线程都唤醒,并先后执行,程序结束。 原文链接:http://www.journaldev...

一个关于Java Thread wait(),notify()的实用例 /// // ProducerConsumer.java // // @author 叶雨 // // 这是个很重要的Thread例子。需要注意的是: // wait() 必须在synchronized 函数或者代码块里面 // wait()会让已经获得synchronized 函数或者代码块控制权的Thread暂时休息,并且丧失控制权 /...
这三个都不是Thread里的方法,而是Object里的方法。即每一个对象都有这三个方法。 wait() 使得当前正持有该对象的锁的线程等待(即暂停),并释放锁,以便其它线程能够获取该对象的锁。 notify() 唤醒一个正在等待该对象锁的线程(即处于wait状态的线程),具体哪一个不确定。
