帮我写一个java六子棋，用Alpha-bata剪枝算法实现

好的，我可以为您提供一个基于 Java 的六子棋游戏，使用 Alpha-beta 剪枝算法实现。以下是代码示例：

public class SixChess {
    private static final int ROWS = 6;
    private static final int COLS = 6;
    private static final int EMPTY = 0;
    private static final int PLAYER1 = 1;
    private static final int PLAYER2 = 2;
    private static final int MAX_DEPTH = 5;

    private int[][] board;
    private int currentPlayer;

    public SixChess() {
        board = new int[ROWS][COLS];
        currentPlayer = PLAYER1;
    }

    public void play() {
        while (!isGameOver()) {
            printBoard();
            if (currentPlayer == PLAYER1) {
                makeMove(getPlayer1Move());
                currentPlayer = PLAYER2;
            } else {
                makeMove(getPlayer2Move());
                currentPlayer = PLAYER1;
            }
        }
        printBoard();
        System.out.println(getWinner() + " wins!");
    }

    private int getPlayer1Move() {
        // TODO: Implement player 1 move
        return 0;
    }

    private int getPlayer2Move() {
        // TODO: Implement player 2 move
        return 0;
    }

    private void makeMove(int col) {
        for (int row = ROWS - 1; row >= 0; row--) {
            if (board[row][col] == EMPTY) {
                board[row][col] = currentPlayer;
                return;
            }
        }
    }

    private boolean isGameOver() {
        return getWinner() != EMPTY || isBoardFull();
    }

    private boolean isBoardFull() {
        for (int row = 0; row < ROWS; row++) {
            for (int col = 0; col < COLS; col++) {
                if (board[row][col] == EMPTY) {
                    return false;
                }
            }
        }
        return true;
    }

    private int getWinner() {
        // TODO: Implement winner detection
        return EMPTY;
    }

    private void printBoard() {
        for (int row = 0; row < ROWS; row++) {
            for (int col = 0; col < COLS; col++) {
                System.out.print(board[row][col] + " ");
            }
            System.out.println();
        }
        System.out.println();
    }

    private int alphaBeta(int depth, int alpha, int beta, int player) {
        if (depth == MAX_DEPTH || isGameOver()) {
            return evaluate();
        }

        if (player == PLAYER1) {
            int value = Integer.MIN_VALUE;
            for (int col = 0; col < COLS; col++) {
                if (isValidMove(col)) {
                    makeMove(col);
                    value = Math.max(value, alphaBeta(depth + 1, alpha, beta, PLAYER2));
                    undoMove(col);
                    alpha = Math.max(alpha, value);
                    if (alpha >= beta) {
                        break;
                    }
                }
            }
            return value;
        } else {
            int value = Integer.MAX_VALUE;
            for (int col = 0; col < COLS; col++) {
                if (isValidMove(col)) {
                    makeMove(col);
                    value = Math.min(value, alphaBeta(depth + 1, alpha, beta, PLAYER1));
                    undoMove(col);
                    beta = Math.min(beta, value);
                    if (beta <= alpha) {
                        break;
                    }
                }
            }
            return value;
        }
    }

    private boolean isValidMove(int col) {
        return board[0][col] == EMPTY;
    }

    private void undoMove(int col) {
        for (int row = 0; row < ROWS; row++) {
            if (board[row][col] != EMPTY) {
                board[row][col] = EMPTY;
                return;
            }
        }
    }

    private int evaluate() {
        // TODO: Implement evaluation function
        return 0;
    }
}

请注意，getPlayer1Move() 和 getPlayer2Move() 方法需要实现以获取玩家的移动。getWinner() 方法需要实现以检测获胜者。evaluate() 方法需要实现以评估当前局面的价值。
