Automobile Packages (Factory pattern) Solution

COP 4814 Lab 7 (20 Points in total)

Automobile Packages (Factory pattern) (15 Points)

You are being asked to write Java code for this lab. When you buy a car, dealers offer add-on

packages with features such as upgraded radios, aluminum wheels, and sunroofs. The

composition of these packages may be somewhat of a mystery to buyers, and the composition

may vary in different geographic regions. For example, in Europe, stricter emission standards,

product availability, and local laws might be factors. At the same time, a car manufacturer wants

to standardize the names and general content of packages to protect their brand. Assume you

are asked to design a software component that assembles the content of two auto packages

("Luxury Bundle" and "Performance Bundle") for three geographic regions (Europe, Asia, North

America), relating to two models of cars sold by a single manufacturer. As you might guess, the

Factory Method pattem can be applied to this problem. Your task is to design AND CODE the

interfaces, abstract classes, and essential concrete classes for this application. Be sure to

create a test class to exhaustively test all possibilities.
