lab class definition 2

Study Display 4.4 (2nd ed. and 3rd ed.) or Display 4.2 & Display 4.3 (1st ed.) and then



1. Comment out date.setDate(6, 17, year); by // date.setDate(6, 17, year);










2. At the next line below, add date.readInput();





3. Run the program again. Fix any problems you may encouter along the way.
4. At the last line of your program, add System.out.println(date.month);
and see what happens. Why?




*month被定義為只有自己可以呼叫自己,所以再另一個程式裡無法呼叫
