继承Thread类的方式创建线程

1 //继承Thread类
2 public class MyThread extends Thread {
3     //重写run方法
4     public void run() {
5         for(int i = 0;i<20;i++) {
6             System.out.println("你好，来自线程"+Thread.currentThread().getName());
7         }
8     }
9 }

1 //测试类
2 public class Test {
3     public static void main(String[] args) {
4         MyThread mythread = new MyThread();
5         MyThread mythread1 = new MyThread();
6         mythread.start();//启动线程
7         mythread1.start();
8     }
9 }
