五、实现Runnable接口

步骤:

  1. 定义MyRunnable类实现Runnable接口
  2. 实现run()方法,编写线程执行体
  3. 创建线程对象(将MyRunnable实例作为线程对象创建时的参数),调用start()方法启动线程

 

代码:

public class MyRunnable implements Runnable{      @Override     public void run() {         for (int i = 0; i < 20; i++) {             System.out.println(我是子线程:+i);         }     }       public static void main(String[] args) {          MyRunnable myRunnable = new MyRunnable();          Thread thread = new Thread(myRunnable);          thread.start();          for (int i = 0; i < 200; i++) {             System.out.println(我是主线程:+i);         }     } }

 

结果:
