What I Learned

Java Programming Concepts

• Object-Oriented Programming: Created classes for Card, Deck, Player, and Game
• Collections Framework: Used ArrayList for managing cards and players
• Exception Handling: Implemented try-catch blocks for user input validation
• Scanner Class: Used for reading user input from the terminal
• HashMap: Created color-to-emoji mappings for better card visualization
