Implement the class as depicted in the UML diagram. Apartment -city: String -area: double -nbOfRooms: int -duplex: boolean +num apt: int +Apartment(----All data fields----) +getCity(): String +getNumberOfStories(): int +assessSize(): String +printDescription(): void 2/3 Data Fields: 1. city: It may consist of one word or two such as "Beirut", "Bint Jbeil", etc. 2. area: its value is expressed in square meter 3. nbOfRooms: with maximum value of 10 4. duplex: either true or false to reflect whether the apartment is made of two stories or only a single one. 5. num_apt: to keep track of how many apartment objects were created. Methods: 1. A constructor that creates an Apartment object with the specified values of all data fields. If the number of rooms passed is greater than 10, then nbOfRooms is set to 0. 2. getCity(): this method returns the city with its letters all capitalized. 3. getNumberOfStories(): This method returns the number of stories of an apartment. If it is duplex, then 2…

How is sub-typing distinct from inheritance? Group of answer choices Sub-typing is a has-a relationship where inheritance is a is-a relationship. They are different names for the same concept. Object-oriented programming uses inheritance, where non-object oriented languages use sub-typing. Inheritance involves reuse of implementations, where sub-typing involves having a shared list of operations that the type can do.

Computer Science The console software for a game needs to be created with an MVC design pattern where game engine is the controller (GameController), the scenes are the views (GameView), and game & gamer info are the models (GameModel). Also, we need the controller, which is the game engine to be built with Singleton design pattern. So, the console software here adopts two co-existing design patterns. You will have to implement the controller class and the driver class. Follow the MVC design pattern implementation shown in the example in Lecture 14 for the Student, its controller, and the corresponding view. Use provided GameView class as the view and the GameModel class as the model. Provide answers to the following questions based on this case study: a) implement GameController Class as Singleton and as the controller for MVC in Java. b) Implement the Driver class. Also add the static method “getFromDB” (provided below) in the Driver class as the mock connection with the…
PROBLEM: Based on the given class diagram, create a class implementation using C++. Voters - active_Account: string - name: string - age: integer - precint_Number: string + setAccount(String account): void + getAccount(): String + setName(String fullname): void + getNamet(): String + setAge(Integer presentAge): void + getAge():Integer + setPrecintNo(String account): void + getPrecintNo ():String NOTE: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. ● Please note that the deactivated voter account must be still part of the "object". Test all the functions by making calls. SAMPLE RUN: You have an Active Voters account! Your full name is Juan Dela Cruz. You are 25 years old. You Precint Number is 125-A. You have an Active Voters account! Your full name is Peter Simon Perez. You are 65 years old. You Precint Number is 347-B. You have an Deactivated Voters account!…
Both abstract classes and interfaces may be used to express common object behaviour.What factors should you consider when deciding whether to utilise an interface or an abstract class?
Elevator (or Lift as referred to by the English folks) Simulator in C language program.Simulate an Elevator-Controller Program. The Elevator should be able to travel between five floorsnamely Ground, 1st, 2nd, 3rd, 4th and 5th floors. The elevator can travel going up (unless they areat the 5th floor) or going down (unless they are at the ground floor). The elevator can only containone passenger (which is the current user of the program). Initially the elevator begins and loads atthe Ground Floor. If the user wants to travel to the 5th floor, the elevator shall go up to the saidfloor. It is the option of the user if they want to alight the elevator or not on the 5th floor or anyfloor on the way. Realistic rules should apply: If the user alights at the 4th floor, when they ride the elevator again, itshould begin traveling from the 4th floor and from there choose to go up or down. Your programshould have some validation: meaning, only the valid characters should be received by the…
