每个等待锁的线程都会被封装成ObjectWaiter 对象,_owner 指向持有ObjectMonitor 对象的线程,当多个线程同时访问同一同步代码块或者同步方法时,首先会进入 _EntryList 队列,当线程获取到monitor 后进入_Owner 区域并把 monitor中的 _Owner 变量设置为当前线程,同时monitor 中的计数器count 加1,若线程调用wait() 方法,将...
one of them is chosen to be awakened. The choice is arbitrary and occurs at the discretion of the implementation. A thread waits on an object's monitor by calling one of the wait methods.

一Monitor 引入 读过我并发编程专栏发布多线程synchronized权威解析一文的同学都知道,Synchronization 是围绕着内部被称为内部锁(intrinsic lock)或者监管锁(Monitor Lock)的实体建立的;那么我们看看Object的notify()方法源码中的一段介绍如下:其意指唤醒一个正在等待对象monitor的线程;如果有多线程在等待这个对象,只有其中...
