import java.util.TimerTask;
class MyTimerTask extends TimerTask{
SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
@Override
public void run() {
// TODO Auto-generated method stub
System.out.println(dateFormat.format(new Date()));
}

}
public class Test {
public static void main(String args[]){
MyTimerTask myTimerTask=new MyTimerTask();
Timer timer=new Timer();
timer.schedule(myTimerTask,1000,1000);
