1 A Fast-Food Restaurant Menu System Imagine that you are asked to write code to support an automated system for taking fastfood restaurant orders, and to implement this for a particular fast-food restaurant of your chosing. The main class RestaurantProg runs a simple interactive interface for a user: to see menu items available to them at your fast food restaurant; to select one or more menu items and add them to their order; and to see a running total price of their order, which 1 accounts for any discounts. Initially, RestaurantProg will only print a menu to screen. Until you complete Section 2, you do not need to edit RestaurantProg. When you get to Section 3, you should uncomment the remaining code in RestaurantProg. You have also been given a class Prices which gives you a simple way of converting int prices into Strings. You do not need to edit this class. You should begin by completing the implementation of Menu, MenuItem and the subclasses of MenuItem, the requirements are described in more detail in Section 2. After which, you should attempt to implement Order, OrderEntry and the implementing classes of OrderEntry, the requirements are described in more detail in Section 3.
