Object-oriented Programming

Object-Oriented Programming

This project is an exercise in object-oriented project design . It creates a Car List project using four classes , one used in defining the nominal class Car , the Car List which holds a collection of Car objects the Car List Demo which tests the project , and an accessory Input Reader class
