This assignment requires you to design, implement and test a program using Java features from the first half of the subject content. You are required to implement in Java all the classes presented in the conceptual model according the specifications provided. You are also required to develop a separate, console based user interface which, when combined with the problem domain classes, forms an executable application. Other than your own classes, your code may use only classes of the Java SE API described in this subject.

It has been significantly simplified to meet the requirements of this subject.
