Chapter 8, Problem 1P

Define a class named Employee whose objects are records for employees. Derive this class from the class Person given in Listing 8.1. An employee record inherits an employee’s name from the class Person. In addition an employee record contains an annual salary represented as a single value of type double, a hire date that gives the year hired as a single value of type int, and an identification number that is a value of type String. Give your class a reasonable complement of constructors, accessor methods and mutator methods, as well as an equals method. Write a program to fully test your class definition.
