从上述打印的结果我们可以看出,使用 notify 并不是随机唤醒的,而是顺序唤醒的,虽然以上代码能证明这个结论,但为了更清楚的解释这个问题,我们查看了 notify 的实现源码,它的源码内容如下: /*** Wakes up a single thread that is waiting on this object's* monitor. If any threads are waiting on this object...

The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until another thread notifies threads waiting on this object's monitor to wake up either through a call to thenotifymethod or thenotifyAllmethod. The thread then waits until it can re-o...
Thrownto indicate that a thread has attempted to wait on anobject's monitor or to notify other threads waiting on an object's monitor without owning the specified monitor. 该错误的大意为:线程试图等待一个对象的监视器或者去通知其他在等待对象监视器的线程,但是该线程本身没有持有指定的监视器.主要是...
wait / notify / notifyAll 和 synchronized method / block,调用wait,notify,notifyAll的代码必须位于synchronized内,否则系统会抛出IllegalMonitorS

This method causes the current thread to place itself in the wait set for this objectand then to relinquish any and all synchronization claims on this object. wait方法会将当前线程放入wait set,等待被唤醒,并放弃lock对象上的所有同步声明。意味着线程A释放了锁,线程B可以重新执行加锁操作。不过又有一...
