Java中定时运行程序

ExecutorService pool = Executors.newSingleThreadExecutor();pool.execute(new Runnable() {public void run() {for(int i=0;i<1000;i++) {try {Thread.sleep((new Random().nextInt(10) + 1) * 1000);} catch (InterruptedException e) {e.printStackTrace();}}}});ScheduledExecutorService timer = Executors.newScheduledThreadPool(1);timer.scheduleAtFixedRate(new Runnable() {public void run() {System.out.println("我在运行");}}}, 1, 1, TimeUnit.SECONDS);
