每秒钟显示当前日期和时间

Question

我想在我的JSP页面上每秒钟打印当前日期和时间，TimerTask类的run（）仅返回void。我如何从此类返回当前时间，请任何Java Geeks帮助我解决这个问题

public  class ITCBillDeskRetrieveTrialDDHHMMSS extends TimerTask
{

    Logger 
         logger=Logger.getLogger(ITCBillDeskRetrieveTrialDDHHMMSS.class);
    public static String retrieveTraialDate;

    @Override
    public void run() 
    {
        try 
        {
            retrieveTraialDate();
        } 
        catch (ParseException | IOException e)
        {
            e.printStackTrace();
        }
    }

    //print Current & Print Date //
    public Date retrieveTraialDate() throws ParseException, IOException
    {
          Date currentDate=new Date();
          System.out.println("Current Date $$$ "+currentDate);
          return currentDate;
    }

    public static void main(String args[]) throws ParseException, 
      IOException
    {
           Timer  timer=new Timer ();
           timer.schedule(new ITCBillDeskRetrieveTrialDDHHMMSS(),0,1000);

    }  
}
