用java代码写五子棋功能的代码

我可以回答你的问题，以下是一个可能的五子棋游戏的Java代码实现：

import java.util.Scanner;

public class Gobang {
    private static char[][] board; // 棋盘
    private static final int BOARD_SIZE = 15; // 棋盘大小
    private static char player = 'X'; // 当前玩家，先手执黑

    public static void main(String[] args) {
        initBoard(); // 初始化棋盘
        printBoard(); // 打印棋盘
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("请 " + player + " 玩家落子，输入行和列的坐标：");
            int row = scanner.nextInt();
            int col = scanner.nextInt();
            if (isValidMove(row, col)) { // 判断落子是否合法
                board[row][col] = player; // 执行落子
                printBoard(); // 打印棋盘
                if (isGameOver(row, col)) { // 判断游戏是否结束
                    System.out.println(player + " 玩家获胜！");
                    break;
                }
                player = (player == 'X') ? 'O' : 'X'; // 切换玩家
            } else {
                System.out.println("落子不合法，请重新输入行和列的坐标！");
            }
        }
        scanner.close();
    }

    private static void initBoard() {
        board = new char[BOARD_SIZE][BOARD_SIZE];
        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                board[i][j] = '-';
            }
        }
    }

    private static void printBoard() {
        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                System.out.print(board[i][j] + " ");
            }
            System.out.println();
        }
    }

    private static boolean isValidMove(int row, int col) {
        if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE) {
            return false; // 落子超出棋盘范围
        }
        if (board[row][col] != '-') {
            return false; // 已有棋子
        }
        return true;
    }

    private static boolean isGameOver(int row, int col) {
        char piece = board[row][col];
        int count = 0;
        // 水平方向
        for (int i = col - 4; i <= col + 4; i++) {
            if (i >= 0 && i < BOARD_SIZE && board[row][i] == piece) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        count = 0;
        // 垂直方向
        for (int i = row - 4; i <= row + 4; i++) {
            if (i >= 0 && i < BOARD_SIZE && board[i][col] == piece) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        count = 0;
        // 正斜方向
        for (int i = -4; i <= 4; i++) {
            int r = row + i;
            int c = col + i;
            if (r >= 0 && r < BOARD_SIZE && c >= 0 && c < BOARD_SIZE && board[r][c] == piece) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        count = 0;
        // 反斜方向
        for (int i = -4; i <= 4; i++) {
            int r = row + i;
            int c = col - i;
            if (r >= 0 && r < BOARD_SIZE && c >= 0 && c < BOARD_SIZE && board[r][c] == piece) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        return false;
    }
}
