Seemed straightforward at first and I kind of rushed into coding without thinking through the class hierarchy.
Start by clarifying requirements (e.g., standard 52-card deck, jokers, multiple decks) and then design classes for Card, Deck, Hand, and Player with clear responsibilities. Implement core operations like shuffle, deal, and reset, and discuss trade-offs such as using enums for suits/ranks and ensuring thread safety if needed.
Pro tip: Demonstrate extensibility by mentioning how to support multiple decks, jokers, or different card games without major refactoring, and discuss the Fisher-Yates shuffle for unbiased randomization.
Ask about the scope: standard 52-card deck, inclusion of jokers, multiple decks, and specific operations needed (shuffle, deal, reset). Confirm if thread safety or persistence is required.
Define classes: Card (suit, rank), Deck (collection of cards), Hand (cards held by a player), and Player (optional). Use enums for Suit and Rank to ensure type safety.
Implement methods: shuffle (Fisher-Yates), deal (remove top card), reset (reinitialize deck), and possibly add/remove cards. Consider returning cards to deck or discarding.
Talk about design choices: using List vs. array, immutability of Card, thread safety (synchronized or concurrent collections), and how to extend for multiple decks or jokers.
Write clean code with proper encapsulation and provide simple tests or usage examples to demonstrate correctness.
