Needs help in editing
Hi guys: Can any one please help me how to i do the changes in my
program according to the following 4 changes.
1) Create a Date type birth data instance field in the Employee class,
not a String
2) Enlarge the constructors for the Employee class and subclasses to
pass the int month, int day, and int year of the birth date as input
by the user to PayrollSystemTest to the subclass constructor, and then
to the Employee class constructor
3) Input from the user for the 5 specific employees and then comment
out the hardcoding for the 4 employees in the original code
4) Report monthly salary amounts and include the November birthday
bonus
