1.2.2实现Runnable接口

package demo;/** * Created by sunyifeng on 17/10/9. */public class MyRunnable implements Runnable {    @Override    public void run(){        System.out.println("Runnable run");    }}

package demo;/** * Created by sunyifeng on 17/10/9. */public class Run {    public static void main(String[] args) {        Runnable runnable = new MyRunnable();        Thread thread = new Thread(runnable);        thread.start();        System.out.println("运行结束");    }}

运行结果：

运行结束
Runnable run

程序说明：

1、Runnable接口可以实现继承+接口；

2、注意Thread类的8个构造方法（见Thread源码）。
