- 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…Question: Implement the following UML class diagrams and test their methods.

- Computer Science UML is a standard language that allows you to capture different aspects of your system in well-defined graphical models. Some of the models capture static aspects for the system and one will capture dynamic behavior for the system. In this project, you are required to draw an activity diagram showing the actions and events involved in depositing a check to a bank account using a mobile app. In particular, your paper should provide the following: A simple pseudo-code that captures the sequence of that process A detailed activity diagram that maps to your pseudo code you identified Make sure to specify clearly any assumptions you feel important to understand your logic I'm a bit lost on what to do and really just need an example of what this is asking and then suggestions on how to go about doing the assignment.Implement the class as depicted in the UML diagram.

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 is…Lab 6 - Preparation Questions ITDR2104 - Programming Lab 6 - Preparation Questions Student ID: Student Name: Group No.: All the questions should be completed before the start of lab-7 session.

Q2: Draw a simple class diagram showing only relationships between the classes. Implementation: After analysing the given requirements, implement the required application: with Object Oriented Programming style following the rules of good programming style (e.g. adding comments, etc.) • using only the material covered in M251 (and its prerequisites) Java language*a.

- Refer to the UML class diagram given below: Subject a) |- subjectTitle: String - creditHour: int - subjectCount: int + Subject() + Subject(subjectTitle: String, creditHour: int) + set and get methods + getSubjectCount ():int + toString():String Implement the complete Subject class that shown in the above diagram. The following requirements must be included: • Use this keyword whenever possible. • The getter and setter for all instance data members. • The parameterized constructor should increase the value of subjectCount by 1. • The toString() method that will return all the information about the Subject object except subjectCount.Computer Science Object Oriented Analysis and Design. Look at the problem described below and describe how you would break it into objects, consider ways to use inheritance and composition. Describe for me how those objects make a system of objects that solves the problem. You may use UML or just write out a list of classes describing their properties and interface. You should also include a short description of how those objects work together. A local travel agent has built a business on using their knowledge of Europe to create custom trips for couples around Europe. For each client they create customized itineraries (a planned route or journey) and book all the travel and lodging accommodations for their high-end clients. For example they might build a custom vacation in Scotland where the client flies into St. Andrews and stays at a castle for 1 night then takes a bus to Pitlochry where they stay at a hotel for 3 nights then take a private plane to Braemar where they stay in a…Programming to be used: Java Instructions: Develop a UML class diagram for the following situations. Your diagram should be able to specify correctly the following: Class Name, Attributes with their corresponding data type and visibility, Methods with their corresponding data type. Use the text editor or MS word to present your answers. Scenarios: 1. The university wants you to design an enrollment system. One of the classes to be considered is class STUDENT. A student during registration can have his ID number. Information about the student (eg. First name, middle name, middle initial, contact number, address, birthday) are asked and stored in the system. These information, however, can be edited. After the registration/admission, a student can enroll subjects, can add subjects and can drop subjects. 2. The same University asks you to design a Human Resource Information System. This is a system that records information and generates reports about the employees in the university. Each…
