Java多线程的sleep休眠的实现

package Demo04;
public class TestSleep  implements Runnable{     //使用Runnable方法创建程序线程
    private  int ticketNums =10;      //有10张票
    @Override
    public void run() {      //重写run方法
        while (true){        //写while  循环
            if (ticketNums<=0){       //当票数小于等于0
                break;       //停止循环
            }
            System.out.println(Thread.currentThread().getName()+"-->拿到了第"+ticketNums--+"票");     //输出信息
        }
    }
    public static void main(String[] args) {    //这是它的主线程
         TestSleep ticket = new TestSleep();        //创建对象
         new Thread(ticket,"小王").start();         //启动线程
         new Thread(ticket,"小李").start();
         new Thread(ticket,"小慧").start();
    }
}
