        Calendar c=Calendar.getInstance();

        SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        System.out.println(simpleDateFormat.format(c.getTime()));

        System.out.println (name + "learning" );

    }

        Timer t = new new Timer ();

        // Create a Student object 

        Student STU = new new Student ( "lili" );

        // get a Calendar object

        the SimpleDateFormat SimpleDateFormat = new new the SimpleDateFormat ( "the MM-dd-YYYY HH: mm: SS" );

        System.out.println(simpleDateFormat.format(c.getTime()));

        // Current delayed 10 seconds 

        c.add (Calendar.SECOND, 10 );

        // call the method Timer

        t.schedule(stu,c.getTime());

    }

}
