1.7.8使用return 停止线程

package com.cky.thread;

/**
 * Created by edison on 2017/12/3.
 */
public class MyThread12 extends Thread{
    @Override
    public void run() {
        super.run();
            for (int i = 0; i < 50000; i++) {
                if (Thread.interrupted()) {
                    System.out.println("子线程已经停止了，我要退出");
                    return;
                }
                System.out.println("i="+(i+1));
            }
            System.out.println("for循环后继续执行");

    }
}

package com.cky.test;

import com.cky.thread.MyThread12;

/**
 * Created by edison on 2017/12/3.
 */
public class Test {
    public static void main(String[] args) {
        try {
            MyThread12 myThread12 = new MyThread12();
            myThread12.start();
            Thread.sleep(2);
            myThread12.interrupt();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

i=137
i=138
i=139
i=140
i=141
i=142
i=143
i=144
i=145
子线程已经停止了，我要退出

用return也能停止线程，不过还是建议抛出异常的方法，因为可以继续往上抛出，让事件传播
