Question
The same description as Problem I. You are asked to display order's item list and meal cost to customer. Each meal must have at least one main item, but side item and drink are optional. Also, a 10% coupon code is available to use. So the main items can be decorated by the side items, drink and coupon. This gives a customer flexibility to order any number of sides or drinks for a meal. Please note that each side item and drink can be multiple or partial. The cost of multiple or partial side and drink is adjusted proportionally, for example, cost of 2 orders of Coke is 2x$1.00, 40% order of Fries is 0.4x$1.5. However, coupon can be used only once per order. We would like to use the Decorator pattern and Singleton pattern to create the receipt to show order's item name, quantity, item unit price, item cost, any coupon applied and final cost. The singleton is to ensure that the coupon can be applied only once in an order. Here is price for each item Main items, Hamburger: $6.5; Cheeseburger: $5.0; Double Cheeseburger: $7.00 Side items, Fries: $1.5; Onion Ring, $1.3 Drink: Coke: $1.00; Sprite: $1.20 4) Give the UML class diagram. 5) Provide the implementation code of the UML class diagram given in question 4) in the programming language of your choice. In the client code, create an order that consists of 1 Hamburger, 1 cheeseburger with 40% fries, 60% Onion Ring and double coke and applying the coupon code "10%Off". The client code should display order items, item quantity, item unit price, item cost, coupon, and final cost. 6) Provide screenshot of the program running result. 7) Now for the similar problem description, you have used two different patterns to implement. Please state the difference of the builder and decorator pattern in your implementation.
