对线程的基本认识3

import java.lang.Thread;
import java.util.Date;


class Runner extends Thread{
	
	public void run(){
		//为了结束run方法定义的变量
		boolean b = true;
		
		while(b){
			System.out.println("====" + new Date());
			try{
				//当某个线程在睡眠时被中断将报出InterruptedException异常
				sleep(1000);
			}catch(InterruptedException e){
				//准备中断线程
				b = false;
			}
		}
	}

}

public class ThreadTest3{
	public static void main(String[] args){
		Runner myThread = new Runner();
		//线程启动
		myThread.start();
		try{
			Thread.sleep(10000);
			//中断Runner的线程
			myThread.interrupt();
		}catch(InterruptedException e){
			return;
		}
	}
}
