- The system to be developed for Williams and Son needs to produce the following slip for a customer once the sale has been concluded. Williams & Son VATnr: 0123456 Product Price Screwdriver R 100 Super glue R 20 Total: R120 Please note: For the purpose of this assignment, assume that a customerwill only purchase one unit of each item.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;…A rail transport company wishes to hold details of train services, stations and operators.

A train is designated as either an InterCity or District train though other types of train are possible. Each train must have an operator and not more than one operator. Each operator has a name and a phone number. The operator can operate many trains (or none at all!) Stations: A station has a name and the number of platforms it has. All stations are classified as either Main or District only. There are no other types of stations. Timetable: A train has a number of stops at a station during its journey. It never visits the same station twice on the same…

- The State of New York certifies firefighters throughout the state and must keep track of all of them, as well as of the state’s fire departments. Each fire department has a unique department number, a name that also identifies its locale (city, county, etc.), the year it was established, and its main telephone number. Each certified firefighter has a unique firefighter number, a name, year of certification, home telephone number, and a rank (firefighter, fire lieutenant, fire captain, etc.) The state wants to record the fire department for which each firefighter currently works and each firefighter’s supervisor. Supervisors are always higher-ranking certified firefighters.
