    //Create object to the class and assign the arguments

    MyTime time2 = new MyTime(555550000);

    //Print the data field

    System.out.println(time2.getHour() + ":" +

      time2.getMinute() + ":" + time2.getSecond());

    //Create object to the class and assign the arguments

    MyTime time3 = new MyTime(5, 23, 55);

    //Print the data field

    System.out.println(time3.getHour() + ":" +

      time3.getMinute() + ":" + time3.getSecond());
