public class ScheduleExecutorServiceDemo {

    public static void main(String[] args) {
        ScheduledExecutorService executorService = Executors
                .newScheduledThreadPool(10);
        //定时执行任务，每隔2秒钟执行一次
        executorService.scheduleWithFixedDelay(new Runnable() {
            @Override
            public void run() {
                System.out.println(new Date());
            }
        }, 0, 2, TimeUnit.SECONDS);
