Question

 import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;import java.util.Timer;import java.util.TimerTask;public class TimerTime {   public static void main(String[] args)  throws Exception {         new  TimerTime().new Time().start();     }       //时间格式  SimpleDateFormat fTime = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");  //内部类继承线程 ，创建一个新线程。  class Time extends Thread {         public void run() {             Timer timer = new Timer();              timer.schedule(new TimerTask() {      //重写run方法                   @Override                 public void run() {                                       System.out.println("现在时间是："+fTime.format(new Date()) );   for(int i=1;i<=2;i++){         System.out.println("I am a cat");               }                                       }             }, Calendar.getInstance().getTime(), 5000);         }     }    }
