线程示范【2】

线程示例【2】

package com.thread;/** * 2010-10-26 * 继承Thread实现线程 * 每秒打印hello world，当打印10次时退出打印 * @author Administrator * */public class Demo2 {public static void main(String args[]){Dog dog=new Dog();dog.start();}}class Dog extends Thread{public void run(){int time=0;while(true){try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}System.out.println("hello,world");time++;if(time==10){//退出，跳出while循环，线程也就死亡break;}}}}
