一、代码如下

package www.tainiu.gui__V2;public class aa__XianCheng__V1 {	public static void main(String[] args) {		// TODO Auto-generated method stub		Cat cat1= new Cat();		Cat cat2= new Cat();		cat1.start();		cat2.start();	}}class Cat extends Thread{	int times= 0;	@Override	public void run() {		// TODO Auto-generated method stub		super.run();		while(true) {			try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}			times ++;			System.out.println("Hello World__"+times+this.getName());			if(times == 10) {				break;			}		}					}}
