Question : In Display 4.7, if the method setDate has the parameter as setDate(int month, int day, int year), what kind of changes should be made in its body of codes?
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); 
"錯誤執行!!!" 因為privte是私密內容,將之改成public即可
