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.
