线程礼让——yield

package com.thread.test;
//将线程从运行状态转为就绪状态
//让cpu重写调度，礼让不一定成功
//测试线程礼让
public class TestYield {

    public static void main(String[] args) {
        MyYield myYield = new MyYield();

        new Thread(myYield,"a").start();
        new Thread(myYield,"b").start();

    }
}


class MyYield implements Runnable{

    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+"线程开始执行");
        Thread.yield();
        System.out.println(Thread.currentThread().getName()+"线程结束执行");
    }
