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.
The model
The conceptual model below depicts a model for recording flight and passenger details associated with a travel agent.
Note that the model has significant shortcomings compared to a real system. For example, in a real system the name of every passenger occupying a seat would be recorded and there would be multiple flights per customer and multiple customers per flight. It has been significantly simplified to meet the requirements of this subject.
