用java帮我写一个扑克牌游戏，最后可以运行出游戏界面，这个扑克牌类游戏要有Card类，Deck类，player类，game类

好的，我可以帮你实现这个扑克牌游戏。首先，我们需要定义Card类，表示一张扑克牌。Card类需要包含花色(suit)和点数(rank)两个属性。

public class Card {
    private String suit;
    private String rank;

    public Card(String suit, String rank) {
        this.suit = suit;
        this.rank = rank;
    }

    public String getSuit() {
        return suit;
    }

    public void setSuit(String suit) {
        this.suit = suit;
    }

    public String getRank() {
        return rank;
    }

    public void setRank(String rank) {
        this.rank = rank;
    }

    @Override
    public String toString() {
        return rank + " of " + suit;
    }
}

接下来，我们需要定义Deck类，表示一副扑克牌。Deck类需要包含一组Card对象，并且需要实现洗牌(shuffle)和发牌(deal)功能。

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class Deck {
    private List<Card> cards;

    public Deck() {
        cards = new ArrayList<>();
        String[] suits = {"Spades", "Hearts", "Diamonds", "Clubs"};
        String[] ranks = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace"};

        for (String suit : suits) {
            for (String rank : ranks) {
                Card card = new Card(suit, rank);
                cards.add(card);
            }
        }
    }

    public void shuffle() {
        Collections.shuffle(cards);
    }

    public Card deal() {
        if (cards.isEmpty()) {
            return null;
        }
        return cards.remove(0);
    }

    public int size() {
        return cards.size();
    }
}

然后，我们需要定义Player类，表示一个玩家。Player类需要包含一个手牌(hand)。

import java.util.ArrayList;
import java.util.List;

public class Player {
    private String name;
    private List<Card> hand;

    public Player(String name) {
        this.name = name;
        hand = new ArrayList<>();
    }

    public void addCard(Card card) {
        hand.add(card);
    }

    public void removeCard(Card card) {
        hand.remove(card);
    }

    public int getHandSize() {
        return hand.size();
    }

    public List<Card> getHand() {
        return hand;
    }

    public String getName() {
        return name;
    }

    @Override
    public String toString() {
        return name + "'s hand: " + hand;
    }
}

最后，我们需要定义Game类，表示一个扑克牌游戏。Game类需要包含一个Deck对象和多个Player对象，并且需要实现发牌和游戏流程。

import java.util.Scanner;

public class Game {
    private Deck deck;
    private Player[] players;

    public Game(int numPlayers) {
        deck = new Deck();
        deck.shuffle();

        players = new Player[numPlayers];
        for (int i = 0; i < numPlayers; i++) {
            players[i] = new Player("Player " + (i+1));
        }
    }

    public void dealCards(int numCards) {
        for (int i = 0; i < numCards; i++) {
            for (Player player : players) {
                Card card = deck.deal();
                player.addCard(card);
            }
        }
    }

    public void play() {
        Scanner scanner = new Scanner(System.in);
        boolean gameOver = false;

        while (!gameOver) {
            for (Player player : players) {
                System.out.println(player);
            }

            System.out.println("Enter player name to play card: ");
            String playerName = scanner.nextLine();

            Player currentPlayer = null;
            for (Player player : players) {
                if (player.getName().equalsIgnoreCase(playerName)) {
                    currentPlayer = player;
                    break;
                }
            }

            if (currentPlayer == null) {
                System.out.println("Invalid player name!");
                continue;
            }

            if (currentPlayer.getHandSize() == 0) {
                System.out.println(currentPlayer.getName() + " wins!");
                gameOver = true;
                break;
            }

            Card cardToPlay = currentPlayer.getHand().get(0);
            currentPlayer.removeCard(cardToPlay);
            System.out.println(currentPlayer.getName() + " played " + cardToPlay);
        }
    }

    public static void main(String[] args) {
        Game game = new Game(4);
        game.dealCards(5);
        game.play();
    }
}

现在，你可以运行Game类，开始玩扑克牌游戏了。
