Java中如何延迟程序运行呢?

Java中程序延迟运行的实现思路

方式1:
   借助java.util.concurrent.TimeUnit包中的方法
     TimeUnit.SECONDS.sleep(1);
       暂停一秒钟
	     或
      TimeUnit.MINUTES.sleep(1);
       暂停一分钟
===================================================
方式2:
   使用
    ScheduledExecutorService和scheduleAtFixedRate或 scheduleWithFixedDelay
    使程序暂停指定时间运行

例:
  每秒运行myTask方法(Java 8)

public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}

Java7中
public static void main(String[] args) {
    final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
    executorService.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            myTask();
        }
    }, 0, 1, TimeUnit.SECONDS);
}

private static void myTask() {
    System.out.println("Running");
}
