Exercise:

Create a class called Employeewhose objects are records for an employee. This class will be a derived class of the class Person. An employee record has an employee's name (inherited from the class Person), an annual salary represented as a single value of type double, a year the employee started work as a single value of type intand a national insurance number (inherited from the class Person), which is a value of type String. Write another class containing a main method to fully test your class definition.

Your class should have a reasonable number of constructors (use both default constructor and constructor with parameters) and accessor methods:

1) to display all people in alphabetical order

2) to display only employees in alphabetical order

3) to find name of a employee based on national insurance number

4) to filter for employees who work for a company for more than 5 years and add 10% to their salary
