JAVA中线程睡眠

* public static void sleep(long millis)throws InterruptedException
 * 在指定的毫秒数内让当前正在执行的线程休眠（暂停执行）
 * 线程睡眠过程中线程处于阻塞状态,当睡眠时间到线程开始执行

public class ThreadSleepDemo {
	public static void main(String[] args) {
		//创建线程对象
		ThreadSleep s1=new ThreadSleep();
		ThreadSleep s2=new ThreadSleep();
		s1.setName("hello");
		s2.setName("java");
		//启动线程
		s1.start();
		s2.start();
	}
}

import java.util.Date;

public class ThreadSleep extends Thread {
	@Override
	public void run() {
		for(int x=0;x<200;x++) {
			System.out.println(this.getName()+":"+x+":"+new Date());
			//睡眠2s之后又互相抢占CPU执行权
			try {
				Thread.sleep(2000);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
