The awakened thread will not be able to proceed until the current thread relinquishes the lock on this object. The awakened thread will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; for example, the awakened thread enjoys no ...
Java线程生命周期 类java.lang.Thread包含一个静态的State enum用于定义每种可能的状态. 在任意的时间点, 线程会处于以下的状态之一: NEW– 新创建的线程, 还未启动(在调用 start() 之前的状态). A thread that has not yet started is in this state. RUNNABLE– 正在运行或已经准备好运行但是在等待资源. e...
import java.util.LinkedList;import java.util.List;import java.util.concurrent.TimeUnit;public class NotifyTest {//等待列表, 用来记录等待的顺序private static List<String> waitList = new LinkedList<>();//唤醒列表, 用来唤醒的顺序private static List<String> notifyList = new LinkedList<>();private ...
The awakened threads will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; the awakened threads enjoy no reliable privilege or disadvantage in being the next thread to lock this object。

The awakened thread will compete in the usual manner with any other threads that might be actively competing to synchronize on this object 被唤醒的线程将会与其它线程去竞争对象锁。(表示被唤醒不代表着马上会执行,除非该线程拿到对象锁。) Only one thread at a time can own an object's monitor.只有...
Thrown to indicate that a thread has attempted to wait on an object's monitor or to notify other threads waiting on an object's monitor without owning the specified monitor. 这句话的意思大概就是:线程试图等待对象的监视器或者试图通知其他正在等待对象监视器的线程,但本身没有对应的监视器的所有权。
at java.lang.Thread.run(Thread.java:748) 出错的代码在:object.wait();。这里我们需要了解以下事实: 无论是执行对象的 wait、notify 还是 notifyAll 方法,必须保证当前运行的线程取得了该对象的控制权(monitor) 如果在没有控制权的线程里执行对象的以上三种方法,就会报 java.lang.IllegalMonitorStateException 异常...
notifyAll(): Wakes up all threads that are waiting on this object's monitor. 这三个方法,都是Java语言提供的实现线程间阻塞(Blocking)和控制进程内调度(inter-process communication)的底层机制。在解释如何使用前,先说明一下两点: 1. 正如Java内任何对象都能成为锁(Lock)一样,任何对象也都能成为条件队列(...
