sleepthread.java

JAVA编程思想源代码 值得一下 很难找的

package chapter13;

public class SleepThread extends Thread {
	public SleepThread(String name) {
		super(name);
	}

	public void run() {
		try {
			int sleepTime = (int) (Math.random() * 100); // 产生随机数
			Thread.currentThread().sleep(sleepTime); // 线程休眠sleepTime毫秒
			System.out.println(getName() + " 休眠了" + sleepTime + " 毫秒");
		} catch (InterruptedException e) { // 由于线程休眠时可能被中断，所以需要捕捉异常
			e.printStackTrace();
		}
	}

	public static void main(String[] args) {
		Thread t1 = new Thread(new SleepThread("线程1"));
		Thread t2 = new Thread(new SleepThread("线程2"));
		Thread t3 = new Thread(new SleepThread("线程3"));
		t1.start();
		t2.start();
		t3.start();
	}
