Chapter 11 Exercise 2, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

11.2 (The Person, Student, Employee, Faculty, and Staff classes) Design a
class named Person and its two subclasses named Student and Employee.
Make Faculty and Staff subclasses of Employee. A person has a name,
address, phone number, and email address. A student has a class status (freshman,
sophomore, junior, or senior). Define the status as a constant. An employee has
an office, salary, and date hired. Use the MyDate class defined in Programming
Exercise 10.14 to create an object for date hired. A faculty member has office
hours and a rank. A staff member has a title. Override the toString method in
each class to display the class name and the person’s name.
Draw the UML diagram for the classes and implement them. Write a test program
that creates a Person, Student, Employee, Faculty, and Staff, and
invokes their toString() methods.
