How Many Classes Are You Going To Create For The Final Projectdescrib

Design a comprehensive class structure for a Casino Simulation involving Slot Machine and Blackjack games. Describe the purpose of each class, including class members such as fields, constructors, and methods. Provide UML diagrams and CRC cards for the design, and develop an academically rigorous paper that discusses the implementation in detail.

Paper For Above instruction

The final project of this course involves creating a robust casino simulation application that encompasses two popular gambling games: Slot Machine and Blackjack. To effectively model this application, a carefully planned class structure is essential. This paper outlines the design of classes, their purposes, attributes, behaviors, UML diagrams, CRC cards, and the rationale behind the design choices, demonstrating the application of object-oriented principles to achieve a scalable, maintainable, and functional system.

Class Design and Responsibilities

The core classes envisioned for this application include Player, CasinoGame (abstract class), SlotMachine, Blackjack, Die, and auxiliary classes such as GameMenu and GameEngine. Each class encapsulates specific responsibilities to promote separation of concerns, reusability, and clarity.

Player Class

The Player class stores essential information about the player, including personal details, account balance, total deposits, and winnings or losses. Its attributes include name, balance, totalDeposits, and totalWinnings. Essential methods include deposit(), withdraw(), updateBalance(), and displayStatus(). This class facilitates tracking the player's financial state and personal interactions.

CasinoGame Abstract Class

The CasinoGame class functions as a base class providing common attributes and methods for all games. It includes methods such as startGame(), endGame(), and displayResults(), with specific implementations provided in its subclasses. This promotes polymorphism, allowing the game menu to invoke methods on CasinoGame> references.

SlotMachine Class

The SlotMachine class inherits from CasinoGame and embodies the slot machine logic. Its primary attributes include the list of symbols (Cherries, Oranges, Plums, Bells, Melons, Bars), the bet amount, and total wins. Methods include spin(), which randomly selects three symbols, compares them, and determines the payout according to matching rules. It also manages user interactions, prompting for bet amounts and handling repeated play via do-while loops.

Blackjack Class

The Blackjack class also extends CasinoGame. Key attributes include the player's total points, AI (dealer) total, and the Die objects used to simulate dice rolls. It contains methods such as playerTurn(), dealerTurn(), determineWinner(), and simulateDiceRoll(). The game loop allows the player to decide whether to roll or stay, with totals managed carefully to prevent exceeding 21. It incorporates dice rolling via the Die class, which encapsulates dice behavior.

Die Class

The Die class models a six-sided die, encapsulating the rolling behavior. It contains an attribute value. Its primary method roll() generates a random number between 1 and 6, which is used during the blackjack game for dice rolls and could be extended for other mini-games or features.

Supporting Classes

GameMenu manages user interface prompts, displays options, and handles input validation. GameEngine oversees the overall flow, coordinates game sessions, manages state, and loops through game selections based on user choices.

UML Diagram

The UML class diagram reflects the inheritance hierarchy, with CasinoGame as a base class and SlotMachine and Blackjack as subclasses. Each class's attributes and methods are mapped, illustrating relationships, composition, and inheritance.

CRC Cards

  • Player:
    • Responsibilities: Store player info, manage balance, deposit/withdraw, display status
    • Collaborators: CasinoGame, GameEngine
  • CasinoGame:
    • Responsibilities: Abstract game interface, start/end game, show results
    • Collaborators: Player, specific game subclasses
  • SlotMachine:
    • Responsibilities: simulate spins, determine winnings, handle user interaction
    • Collaborators: Die, Player
  • Blackjack:
    • Responsibilities: simulate blackjack rounds, manage dice rolls, determine winner
    • Collaborators: Die, Player
  • Die:
    • Responsibilities: simulate dice roll

Design Rationale and Conclusion

This class design leverages object-oriented principles such as inheritance, encapsulation, polymorphism, and modularity to build a flexible, extensible application. By abstracting common features into the CasinoGame base class, adding new games in future can be simplified. The Player class centralizes user data management, ensuring consistency and maintainability. The UML diagrams and CRC cards support understanding and communication among developers.

In summary, the articulated class structure yields a cohesive and scalable casino simulation platform, illustrating best practices in software design for gaming applications. Proper implementation of these classes, supported by rigorous testing and validation, will result in an engaging user experience and a maintainable codebase.
