线程礼让

package ow.Java.code.Thread;

public class RunnableYield {
    public static void main(String[] ARGS){
        MyTr myTr = new MyTr();
            Thread t1 = new Thread(myTr,"a");
            Thread t2 = new Thread(myTr,"b");
            Thread t3 = new Thread(myTr,"c");
            t1.start();
            t2.start();
            t3.start();
    }
}

class MyTr implements Runnable{
    public void run() {
        for(int i = 0; i < 9; i++){
            if(i == 3){
                System.out.println(Thread.currentThread().getName()+""+i);
                Thread.currentThread().yield();//线程礼让
            }
        }
    }
}

输出结果 

a3
c3
b3

总结

在某种程度上交替执行 就是不让一个家伙过多的连续运行
