java runnable接口实现多线程

1 class MyThread implements Runnable{
2     private String name;
3     public MyThread(String name){
4         this.name=name;
5     }
6     public void run(){
7         for(int i=0;i<10;i++){
8             System.out.println(name+" 运行，i="+i);
9         }
10     }
11 }
12 public class ThreadDemo {
13     public static void main(String[] args) {
14         MyThread mt1=new MyThread("线程A");
15         MyThread mt2=new MyThread("线程B");
16         Thread m1=new Thread(mt1);
17         Thread m2=new Thread(mt2);
18         m1.start();
19         m2.start();
20     }
