Card-Game

Today we brought our card game to life, implementing a complete multiplayer High Card game while diving deeper into Java’s object-oriented features. The code changes from this session can be found here. Day 5 Summary Overview Built a complete multiplayer High Card game while exploring Java’s object-oriented features, modern syntax, and clean code practices. Environment & Tools Git workflow with feature branching zsh git shortcuts for efficient version control Proper package organization Concepts Covered Domain Modeling Record types for immutable data (Card, GameResult) Class design for mutable state (Player, Game) Enum implementation with behavior Clean separation of concerns Modern Java Features Records with validation Enhanced enum capabilities String formatting Stream operations for collections Optional for null safety Design Patterns & Principles Dependency Injection (IO handling) Immutable value objects Builder pattern for game setup Interface segregation Single Responsibility Principle Console Interface Interactive gameplay Input/Output abstraction Error handling User feedback Game state management Implementation Progress Created core game entities Implemented deck management Added player validation Built interactive console interface Established proper error handling Key Takeaways Java enums can contain behavior Records provide clean immutable data structures Dependency injection enhances testability Clean separation between domain and UI Proper error handling improves user experience Next Steps Ready to explore: ...

Today we wrapped up our reservation system implementation and embarked on an exciting new project - a card game that will help us explore more Java concepts. The code changes from this session can be found here. Day 4 Summary Overview Completed the reservation system implementation and started a new card game project, focusing on clean domain modeling and modern Java features. Environment & Tools Practiced proper Git workflow Feature branch management Meaningful commit messages Branch switching and merging Used zsh Git shortcuts effectively Concepts Covered Reservation System Completion Optional usage for null safety Queue operations (peek vs poll) Stream operations for collection manipulation Proper exception handling Event notification patterns Card Game Foundation Domain modeling with immutable types Enum usage and customization String manipulation utilities Collection operations Modern Java Features Records for immutable data Enhanced switch expressions String formatting List operations (removeLast) Stream collectors Design Patterns & Principles Immutable value objects Single responsibility principle Utility class patterns Clean code naming conventions Implementation Progress Completed ReservationService implementation Created foundation for card game: Card, Rank, and Suit implementations Deck management Card drawing mechanisms toString representations Key Takeaways Java’s modern features support clean, expressive code Importance of proper string representation Value of distinguishing between display and debug formats Collection choice impacts performance Next Steps Ready to explore: ...
