Customer and Employee data (15 pts)

Problem Description:

Write a program that uses inheritance features of object-oriented programming, including method overriding and polymorphism.

Console

Welcome to the Person Tester application

Create customer or employee? (c/e): c

Enter first name: Frank

Enter last name: Jones

Enter email address: frank44@ hot mail. com

Customer number: M10293

You entered:

Name: Frank Jones

Email: frank44@hot mail . com

Customer number: M10293

Continue? (y/n): y

Create customer or employee? (c/e): e

Enter first name: Anne

Enter last name: Prince

Enter email address: anneP@ g m ail . com

Social security number: 111-11-1111

You entered:

Name: Anne Prince

Email: anneP@ g mail . com

Social security number: 111-11-1111

Continue? (y/n): n

Operation

The application prompts the user to enter a customer or an employee.

If the user selects customer, the application asks for name, email, and customer number.

If the user selects employee, the application asks for name, email, and social security number.

When the user finishes entering data for a customer or employee, the application displays the data that the user entered.

Specifications

Create a Person class that stores first name, last name, and email address. This class should provide a no-argument constructor, get and set methods for each piece of data, and it should override the toString method so it returns the first name, last name, and email fields in this format:

Name: Frank Jones
Email: frank44@ hot mail . com

In addition, it should contain an abstract method named getDisplayText that returns a string.

Create a class named Customer that inherits the Person class. This class should store a customer number, it should provide get and set methods for the customer number, it should provide a no-argument constructor, and it should override the toString method of the Person class. The toString method should return a string that consists of the string returned by the toString method of the Person class appended with the Customer number like this:

Name: Frank Jones
Email: frank44@ hot mail . com
Customer number: M10293

Create a class named Employee that inherits the Person class. This class should store a social security number, it should provide get and set methods for the social security number, it should provide a no-argument constructor, and it should override the toString method of the Person class. The toString method should return a string that consists of the string returned by the toString method of the Person class appended with the Employees social security number like this:

Name: Anne Prince
Email: anneP@ g mail . com
Social security number: 111-11-1111

Create a class named PersonApp that prompts the user as shown in the console output. This class should create the necessary Customer and Employee objects from the data entered by the user, and it should use these objects to display the data to the user. To print the data for an object to the console, this program should use a static method named print – defined in this class - with the following header (polymorphism):

               public static void print (Person p)
