The question says remodel them. So please send the code for each class and explain how you remodeled them.

13. (30 Pts) Inspect the following three classes. Keeping good OOP practices (such as inheritance, encapsulation, interface segregation, etc.) in mind, remodel them. (i.e., Create new classes -from these three classes- that follow OOP principles more closely) NOTE: You do not have to provide the code that is inside the methods. If you choose to use getters/setters, just writing " getXXX/setXXX {} is enough unless there is something interesting going on inside them (like validation or lazy initialization)
