在Java API中,wait方法的定义如下: public final void wait() throwsInterruptedException Causes the current thread to wait until another thread invokes thenotify()method or thenotifyAll()method for this object. In other
基于以上认知,下面这个是使用wait和notify函数的规范代码模板: [java]view plaincopy 1. // The standard idiom for calling the wait method in Java 2. synchronized (sharedObject) { 3. while (condition) { 4. sharedObject.wait(); 5. // (Releases lock, and reacquires on wakeup) 6. } 7. //...

This method causes the current thread to place itself in the wait set for this object and 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...

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways: By executing a synchronized instance method of that object. By executing the body of asynchronizedstatement that synchronizes...
