Answer 1

wirite this in Constructor

ActionListener taskPerformer = new ActionListener() {

             @Override

            public void actionPerformed(ActionEvent evt) {
               jMenu11.setText(CurrentTime());
            }
        };

        Timer t = new Timer(1000, taskPerformer);
        t.start();

And this Write out Constructor

public String CurrentTime(){

       Calendar cal = new GregorianCalendar();
       int second = cal.get(Calendar.SECOND);
       int min = cal.get(Calendar.MINUTE);
       int hour = cal.get(Calendar.HOUR);
       String s=(checkTime(hour)+":"+checkTime(min)+":"+checkTime(second));
       jMenu11.setText(s);
       return s;

   }

   public String checkTime(int t){
String time1;
if (t < 10){
    time1 = ("0"+t);
    }
else{
    time1 = (""+t);
    }
return time1;

}
