Java学习-072-多线程05：线程休眠 Thread.sleep()

可通过 Thread.sleep(millis)  实现线程的休眠，用于实际业务需求开发需要的等待时间。示例源代码如下所示：

package com.fanfengping.demo;

import lombok.extern.slf4j.Slf4j;

@Slf4j
public class Demo09RunnableSleep implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i < 5; i++) {
            if (i > 1) {
                try {
                    log.info("{} 开始休眠", Thread.currentThread().getName());
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            log.info("{} 运行，i = {}", Thread.currentThread().getName(), i);
        }
    }

    public static void main(String[] args) {
        Demo09RunnableSleep demo09RunnableSleep = new Demo09RunnableSleep();

        Thread threadJoin = new Thread(demo09RunnableSleep, "线程休眠");
        threadJoin.start();
    }
}

程序输出如下所示：
