- 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.

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.

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…
