Question

Create College.java to display information about students and faculty at your college.
USE THE DBPM TEMPLATE AT THE BOTTOM !!!

Specifications

Use the DBPM Class Construction Format to create all of the classes, attributes and methods.

·         Create a Person class. The class stores first name, last name, and email address.
·         Create a class named Student that extends the Person class.
       This class stores a student id, major, student level (freshman, sophomore, junior, or senior).

·         Create a College class with the main method.

Student (example data)

Name: Frank Jones
Email: frank44@hotmail.com
Student id: M10293
Major: Business
Level: Sophomore

·         Create a class named Instructor that inherits from the Person class. This class stores a social security number, subject area taught and number of years worked as an instructor.

Faculty (example data)

Name: Anne Price
Email: anne@nctc.edu
Social security number: 111-11-1111
Subject area: Physics for 3 years.

Ask if you want to see the student or instructor information. Based on the response, display the appropriate information. The individual subclasses should handle the information for the student and the instructor.

--------------------

Further clarification:

In main, ask if they are a student or an instructor. Create the appropriate object and update the attributes. Then based on their response for a student or instructor, you will either go to the Student class or the Instructor class and display the information.

For extra credit (10 points): Create an array of student and instructor objects to store multiple instances.

Example output for the program on inheritance:

Are you a student or instructor: student

OUTPUT:
Name: Frank Jones
Email: frank44@hotmail.com
Student id: M10293
Major: Business
Level: Sophomore

Are you a student or instructor: instructor

OUTPUT:
Name: Anne Price
Email: anne@nctc.edu
Social security number: 111-11-1111
Subject area: Physics for 3 years.
