I’m working on a java discussion question and need an explanation and answer to help me learn.

One of the central concepts of Object-Oriented Programming is class inheritance. This allows a new custom class to inherit and extend the properties and methods of a base class to suit the specific needs of the application.

Example:

“Cars” (base class) (level 1)

bodyStyle (property)

color (property)

Gasoline (inherits from “Cars”) (level 2)

• displacement (property)
• emissions (property)

Electric (inherits from “Cars”) (level 2)

batterySize (property)

• regenerativeBraking (property)
• Ford (inherits from “Gasoline”) (level 3)

model (property)

(additional properties – features, options and accessories)

• Tesla (inherits from “Electric”) (level 3)
• model (property)

(additional properties – features, options and accessories)

Using your knowledge, experience and ideas, and considering what you’ve learned from the unit learning activities and other resources, create a set of custom classes in three inheritance levels for an application for a business or organization (like the example above). You will not program this application, just think about it and discuss it. The first level, consisting of a single custom class, should represent the highest conceptual level, with each subsequent level being more specific and more likely to apply to a real product or service. The second and third levels should have 2-3 classes each, with the classes on the third level inheriting from classes in the second level.
