用Java编写五子棋

好的，以下是一个简单的Java五子棋游戏实现示例：

首先，我们需要创建一个棋盘类来表示游戏状态。这个类应该包含一个二维数组来表示每个位置的棋子状态，一个方法来判断游戏是否结束，以及一些方法来放置棋子和计算得分等。

public class ChessBoard {
    private int[][] board;
    private int size;
    private int winLength;

    public ChessBoard(int size, int winLength) {
        this.board = new int[size][size];
        this.size = size;
        this.winLength = winLength;
    }

    public boolean placeChess(int x, int y, int color) {
        if (x < 0 || x >= size || y < 0 || y >= size || board[x][y] != 0) {
            return false;
        }
        board[x][y] = color;
        return true;
    }

    public boolean isGameOver() {
        return checkHorizontal() || checkVertical() || checkDiagonal();
    }

    private boolean checkHorizontal() {
        for (int i = 0; i < size; i++) {
            for (int j = 0; j <= size - winLength; j++) {
                int count = 0;
                for (int k = 0; k < winLength; k++) {
                    if (board[i][j+k] == board[i][j]) {
                        count++;
                    }
                }
                if (count == winLength) {
                    return true;
                }
            }
        }
        return false;
    }

    private boolean checkVertical() {
        for (int i = 0; i <= size - winLength; i++) {
            for (int j = 0; j < size; j++) {
                int count = 0;
                for (int k = 0; k < winLength; k++) {
                    if (board[i+k][j] == board[i][j]) {
                        count++;
                    }
                }
                if (count == winLength) {
                    return true;
                }
            }
        }
        return false;
    }

    private boolean checkDiagonal() {
        for (int i = 0; i <= size - winLength; i++) {
            for (int j = 0; j <= size - winLength; j++) {
                int count1 = 0;
                int count2 = 0;
                for (int k = 0; k < winLength; k++) {
                    if (board[i+k][j+k] == board[i][j]) {
                        count1++;
                    }
                    if (board[i+k][j+winLength-1-k] == board[i][j]) {
                        count2++;
                    }
                }
                if (count1 == winLength || count2 == winLength) {
                    return true;
                }
            }
        }
        return false;
    }

    public int getScore(int color) {
        int score = 0;
        for (int i = 0; i < size; i++) {
            for (int j = 0; j < size; j++) {
                if (board[i][j] == color) {
                    score++;
                }
            }
        }
        return score;
    }
}

接下来，我们需要创建一个玩家类来放置棋子。这个类可以通过控制台或图形用户界面实现。

public class Player {
    private int color;

    public Player(int color) {
        this.color = color;
    }

    public int getColor() {
        return color;
    }

    public void makeMove(ChessBoard board) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Player " + color + " make a move (x y): ");
        int x = scanner.nextInt();
        int y = scanner.nextInt();
        if (!board.placeChess(x, y, color)) {
            System.out.println("Invalid move, please try again.");
            makeMove(board);
        }
    }
}

最后，我们需要创建一个游戏控制类来协调棋盘和玩家之间的交互。

public class Game {
    private ChessBoard board;
    private Player[] players;
    private int currentPlayerIndex;

    public Game(int size, int winLength, Player[] players) {
        this.board = new ChessBoard(size, winLength);
        this.players = players;
        this.currentPlayerIndex = 0;
    }

    public void start() {
        while (!board.isGameOver()) {
            Player currentPlayer = players[currentPlayerIndex];
            board.print();
            currentPlayer.makeMove(board);
            currentPlayerIndex = (currentPlayerIndex + 1) % players.length;
        }
        board.print();
        int winner = getWinner();
        if (winner == 0) {
            System.out.println("Game ended in a draw.");
        } else {
            System.out.println("Player " + winner + " wins!");
        }
    }

    private int getWinner() {
        int score1 = board.getScore(players[0].getColor());
        int score2 = board.getScore(players[1].getColor());
        if (score1 > score2) {
            return players[0].getColor();
        } else if (score2 > score1) {
            return players[1].getColor();
        } else {
            return 0;
        }
    }
}

现在我们可以创建两个玩家并启动游戏了：

public static void main(String[] args) {
    Player player1 = new Player(1);
    Player player2 = new Player(2);
    Game game = new Game(15, 5, new Player[] { player1, player2 });
    game.start();
}

这是一个非常基本的五子棋游戏实现示例，您可以根据自己的需要和技术水平进行修改和扩展。
