十五、线程礼让
- 礼让线程,让当前正在执行的线程暂停,但不阻塞
- 将线程从运行状态转为就绪状态
- 让cpu重新调度,礼让不一定成功!看CPU心情
代码:
public class ThreadYield implements Runnable{
public static void main(String[] args) {
ThreadYield threadYield = new ThreadYield();
new Thread(threadYield,"A").start();
new Thread(threadYield,"B").start();
}
@Override
public void run() {
System.out.println(Thread.currentThread().getName()+"线程开始");
Thread.yield();
System.out.println(Thread.currentThread().getName()+"线程结束");
}
}
结果:
礼让成功:
