java Timer测试定时调用及固定时间执行代码示例

public class TimerTest2 {  public static void main(String[] args) throws InterruptedException {    Timer timer = new Timer();    timer.schedule(new MyTask(0), 1000, 10000);    //timer.schedule(new MyTask(1), 1000, 10000);  }  static class MyTask extends TimerTask {    private final int i;    public MyTask(int i) {      this.i = i;    }    @Override    public void run() {      System.out.println(i + "dddd" + DateTimeUtil.getDateTimeString("yyyy-MM-dd HH:mm:ss.SSS"));      try {        if (i == 0) {          Thread.sleep(8000L);        } else {          Thread.sleep(13000L);        }      } catch (Exception e) {        e.printStackTrace();      }    }  }}

public class TimerTest2 {  public static void main(String[] args) throws InterruptedException {    Timer timer = new Timer();    //timer.schedule(new MyTask(0), 1000, 10000);    timer.schedule(new MyTask(1), 1000, 10000);  }  static class MyTask extends TimerTask {    private final int i;    public MyTask(int i) {      this.i = i;    }    @Override    public void run() {      System.out.println(i + "dddd" + DateTimeUtil.getDateTimeString("yyyy-MM-dd HH:mm:ss.SSS"));      try {        if (i == 0) {          Thread.sleep(8000L);        } else {          Thread.sleep(13000L);        }      } catch (Exception e) {        e.printStackTrace();      }    }  }}
