线程demo1

package Thread;

import java.util.Date;

public class ThreadDemo1 {
	public static void main(String[] args) {
		Thread1 thread1 = new Thread1();
		Thread thread = new Thread(thread1);
		thread.start();
		try {
			Thread.sleep(10000);
			thread1.shutDown();// 主线程休眠10s后，停止thread线程的打印
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
	}
}

class Thread1 implements Runnable {
	boolean flag = true;

	public void shutDown() {
		flag = false;
	}

	@Override
	public void run() {
		while (flag) {// 每隔1s打印一次日期
			System.out.println("time is " + new Date());
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				return;
			}
		}
	}
}

结果如下：

time is Tue Dec 17 17:14:12 CST 2013
time is Tue Dec 17 17:14:13 CST 2013
time is Tue Dec 17 17:14:14 CST 2013
time is Tue Dec 17 17:14:15 CST 2013
time is Tue Dec 17 17:14:16 CST 2013
time is Tue Dec 17 17:14:17 CST 2013
time is Tue Dec 17 17:14:18 CST 2013
time is Tue Dec 17 17:14:19 CST 2013
time is Tue Dec 17 17:14:20 CST 2013
time is Tue Dec 17 17:14:21 CST 2013

该代码实现的功能就是用一个线程每隔一秒打印一次当前日期时间，直到10秒过后，主线程把该线程停止。
