Java设置定时器以暂停和重置定时器

   private static Timer timer;

   public static void main(String[] args) {

       timer = new Timer();

       TimerTask task = new TimerTask() {

           @Override

           public void run() {

               // 定时执行的任务逻辑

               System.out.println("定时任务执行了");

           }

       };

       // 安排任务在延迟1秒后执行，然后每隔2秒重复执行

       timer.schedule(task, 1000, 2000);

       // 暂停定时器

       timer.cancel();

       // 重置定时器

       timer = new Timer();

       timer.schedule(task, 5000, 3000);

   }

   private static ScheduledExecutorService executor;

   public static void main(String[] args) {

       executor = Executors.newScheduledThreadPool(1);

       Runnable task = new Runnable() {

           @Override

           public void run() {

               // 定时执行的任务逻辑

               System.out.println("定时任务执行了");

           }

       };

       // 安排任务在延迟1秒后执行，然后每隔2秒重复执行

       executor.scheduleAtFixedRate(task, 1, 2, TimeUnit.SECONDS);

       // 暂停定时器

       executor.shutdown();

       // 重置定时器

       executor = Executors.newScheduledThreadPool(1);

       executor.scheduleAtFixedRate(task, 5, 3, TimeUnit.SECONDS);

   }
