定时任务

最近不知怎的，不想动，啥都不想干，也不想上班打工。哎！不打工，咋整呢？

定时任务：
import java.util.Timer;
import java.util.TimerTask;
public class Task2 {
  public static void main(String[] args) {
    TimerTask task = new TimerTask() {
      @Override
      public void run() {
        // task to run goes here
        System.out.println("Hello !!!");
      }
    };
    Timer timer = new Timer();
    long delay = 0;
    long intevalPeriod = 1 * 1000;
    // schedules the task to be run in an interval
    timer.scheduleAtFixedRate(task, delay,
                                intevalPeriod);
  } // end of main
}

import java.util.Timer;
import java.util.TimerTask;
public class Task2 {
  public static void main(String[] args) {
    TimerTask task = new TimerTask() {
      @Override
      public void run() {
        // task to run goes here
        System.out.println("Hello !!!");
      }
    };
    Timer timer = new Timer();
    long delay = 0;
    long intevalPeriod = 1 * 1000;
    // schedules the task to be run in an interval
    timer.scheduleAtFixedRate(task, delay,
                                intevalPeriod);
  } // end of main
}

import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
public class Task3 {
  public static void main(String[] args) {
    Runnable runnable = new Runnable() {
      public void run() {
        // task to run goes here
        System.out.println("Hello !!");
      }
    };
    ScheduledExecutorService service = Executors
                    .newSingleThreadScheduledExecutor();
    service.scheduleAtFixedRate(runnable, 0, 1, TimeUnit.SECONDS);
  }
}
其实也没啥新意，记录贴！非原创
