您需要获取显示器this在你打电话之前notify()。此外,你打电话的时候wait()你应该在一个循环中这样做,检查一个条件,以确定你没有经历过虚假的唤醒。 publicrunCalculations(Data data){ globalData=data; synchronized(this) { calculating=true; this.notify(); } } publicvoidrun(){ while(true){ synchronized(...
javamultithreadingwaitnotify 57 为什么 wait() 和notify() 方法在 Object 类中声明,而不是在 Thread 类中? - Bhupi9个回答 46 因为你需要等待给定的对象(或具体来说,它的监视器)才能使用此功能。 我认为你可能误解了这些方法的工作原理。它们并不仅仅是在线程级别上运行,也就是说调用wait()方法并被下一...
// Java program to demonstrate the use of wait() method classGunFight{ privateintbullets=40; // This method fires the number of bullets that are // passed it. When the bullet in magazine becomes zero, // it calls the wait() method and releases the lock. synchronizedpublicvoidfire(intbul...
This article explains the wait(), notify() and notifyAll() methods in Java. It explains how to use them for inter thread communication and synchronization.
最明显的区别,两者都存在不同的包,wait() 方法是在 java.lang.Object 类中声明的,而 join() 是在 java.lang.Thread 类中声明的。 wait() 用于线程间通信,而 join() 用于在多个线程之间添加排序,一个线程在第一个线程执行完成后开始执行。 我们可以使用 notify() 和 notifyAll() 方法启动一个等待线程(通...
To avoid polling, Java includes an elegant interrocess communication mechanism via the wait(), notify(), and notifyAll() methods. These methods are implemented as final methods in Object, so all classes have them. All three methods can be called only from within a synchronized method. Althoug...
