Question

Java Object Oriented Programming:

The Program consists of three classes. The Super class (Main Class) and two sub-classes. The Superclass creates 5 car objects and saves details such as car company, car model and year built (For all 5 cars).

The second class (Sub-class) saves the dealer address, and zip code (For all 5 cars).

The third (Sub-class) saves the color, type of car (Hybrid, sports etc.) for all 5 cars.

The Main Function displays a menu that displays the info from each class.

Example of the Menu;

Type The number

1. Displays all the Car models

2. Displays the address of all the car dealer addresses

3. Display all different colors

4. Displays all the info

(If the User types 1, it will display all the car models and if the User types 3 it will display all the different car colors and so on ...)
