在程序中允许一个线程进行暂时的休眠，直接使用Thread.sleep()方法即可实现休眠：

class myThread11 implements Runnable {
    public void run() {
        for (int i = 0; i < 5; i++) {
            try {
                Thread.sleep(5000);
                System.out.println(Thread.currentThread().getName()
                        + " running " + i);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }
}

public class ThreadSleepDemo {
    public static void main(String[] args) {
        myThread11 m = new myThread11();
        new Thread(m, "von‘s thread").start();
    }
}

当一个线程运行时，另外一个线程可以直接通过interrupt（）方法中断其运行状态：

class myThread12 implements Runnable {
    public void run() {
        System.out.println("1,Begin run() method:");
        try {
            Thread.sleep(10000);
            System.out.println("2,Sleep have overd.");
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            System.out.println("3,Sleep be stoped.");
            return;
        }
        System.out.println("4,Stop run() method normally.");
    }
}

public class ThreadInteruptDemo {
    public static void main(String[] args) {
        myThread12 vMyThread = new myThread12();
        Thread thread = new Thread(vMyThread, "vThread");
        thread.start();
        try {
            thread.sleep(2000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        thread.interrupt();
    }
}
