两人对弈的五子棋游戏java代码

五子棋是一种古老的策略性棋类游戏，通常由两个玩家轮流下棋。下面是一个简单的用Java实现的两人对弈的五子棋游戏代码：

import java.util.Scanner;

public class GomokuGame {
    private char[][] board;
    private int currentPlayer;
    private boolean isGameOver;
    
    public GomokuGame() {
        board = new char[15][15];
        currentPlayer = 1;
        isGameOver = false;
    }
    
    public void playGame() {
        Scanner scanner = new Scanner(System.in);
        
        while (!isGameOver) {
            System.out.println("玩家 " + currentPlayer + " 的回合");
            System.out.print("请输入行号和列号（以空格分隔）：");
            int row = scanner.nextInt();
            int col = scanner.nextInt();
            
            if (isValidMove(row, col)) {
                makeMove(row, col);
                printBoard();
                
                if (checkWin(row, col)) {
                    isGameOver = true;
                    System.out.println("玩家 " + currentPlayer + " 获胜！");
                } else if (isBoardFull()) {
                    isGameOver = true;
                    System.out.println("平局！");
                }
                
                currentPlayer = (currentPlayer == 1) ? 2 : 1; // 切换玩家
            } else {
                System.out.println("无效的移动，请重新输入");
            }
        }
        
        scanner.close();
    }
    
    public boolean isValidMove(int row, int col) {
        return (row >= 0 && row < 15 && col >= 0 && col < 15 && board[row][col] == '\u0000');
    }
    
    public void makeMove(int row, int col) {
        board[row][col] = (currentPlayer == 1) ? 'X' : 'O';
    }
    
    public boolean checkWin(int row, int col) {
        char symbol = (currentPlayer == 1) ? 'X' : 'O';
        
        // 检查横向是否有五子连线
        int count = 0;
        for (int i = Math.max(0, col - 4); i <= Math.min(14, col + 4); i++) {
            if (board[row][i] == symbol) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        
        // 检查纵向是否有五子连线
        count = 0;
        for (int i = Math.max(0, row - 4); i <= Math.min(14, row + 4); i++) {
            if (board[i][col] == symbol) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        
        // 检查左上到右下斜线是否有五子连线
        count = 0;
        for (int i = Math.max(row - 4, 0), j = Math.max(col - 4, 0); i <= Math.min(row + 4, 14) && j <= Math.min(col + 4, 14); i++, j++) {
            if (board[i][j] == symbol) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        
        // 检查左下到右上斜线是否有五子连线
        count = 0;
        for (int i = Math.min(row + 4, 14), j = Math.max(col - 4, 0); i >= Math.max(row - 4, 0) && j <= Math.min(col + 4, 14); i--, j++) {
            if (board[i][j] == symbol) {
                count++;
                if (count == 5) {
                    return true;
                }
            } else {
                count = 0;
            }
        }
        
        return false;
    }
    
    public boolean isBoardFull() {
        for (int i = 0; i < 15; i++) {
            for (int j = 0; j < 15; j++) {
                if (board[i][j] == '\u0000') {
                    return false;
                }
            }
        }
        
        return true;
    }
    
    public void printBoard() {
        for (int i = 0; i < 15; i++) {
            for (int j = 0; j < 15; j++) {
                System.out.print(board[i][j] == '\u0000' ? '-' : board[i][j]);
            }
            System.out.println();
        }
    }
    
    public static void main(String[] args) {
        GomokuGame game = new GomokuGame();
        game.playGame();
    }
}

以上就是实现两人对弈的五子棋游戏的简单Java代码。玩家可以依次输入行号和列号来下棋，当有一方连成五子时，游戏结束并宣布获胜者。如果棋盘已满而无法继续下棋，则宣布平局。
