Question

Hi I need help creating a program in JAVA. This is material from chapter 9 Objects and Classes from the Intro to JAVA textbook.

Mrs. Quackenbush's Rent-A-Wreck car rental ..... Mrs. Q asked you to create a program that can help her track her growing fleet of junkers. Of course she expects you to use your best programming skills, including:

1. Plan and design what attributes/actions an automobile in a rental fleet should have (example. Track number of Trucks, SUVs, and Cars. Each category of vechicles could come in one of three colors: White, Silver, and Black.)

2. The construction of a class or classes that will make the code:

reusable

encapsulated

easy to change (all code will change eventually?)

free from duplicate code

use constructors, attributes and methods to simulate real-life entities

have the ability to inherit from other classes (Have instructor discuss)

use conventions common to the language and your current class

----------------------------Vehicle.java-------------------------
