Vehicle Registration System

A JAVA vehicle registration system that maintains a log of indivdual vehicle registrations. Each registration represents a different vehicle and all its attributes, as well as its owner and owner’s information, and the vehicle’s jurisdiction information. The registration system was designed using SOLID design practices and was delivered as part of an OBJECT-ORIENTED DESIGN class. It utilizes proper encapsulation practices such as a singleton class to represent the registration system and establishes class protocols through interfaces to improve reusability. The system also implements Java HIGHER-ORDER FUNCTIONS to enable filtering of the different vehicle registrations.

System tests were ran using JUNIT following a specific rubric. Tests can be found in the test directory.

• Vehicle: Extends vehicle interface to represent a type of vehicle as well as its corresponding information.
• Red/Blue/Green Jurisdiction: Classes that represent different vehicle jurisdiction and use dynamic dispatch to return specific tax information per jurisdiction.
