五子棋java代码

以下是一个简单的五子棋Java代码示例：

import java.util.Scanner;

public class Gomoku {
    private static int size = 15; // 棋盘大小
    private static char[][] board = new char[size][size]; // 棋盘
    private static char player1 = 'X'; // 玩家1棋子
    private static char player2 = 'O'; // 玩家2棋子
    private static int turn = 0; // 轮到哪个玩家
    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        initBoard(); // 初始化棋盘
        printBoard(); // 打印棋盘
        while (true) {
            int x = getPlayerInput("x"); // 获取玩家输入的x坐标
            int y = getPlayerInput("y"); // 获取玩家输入的y坐标
            // 验证输入是否合法
            if (x < 0 || x >= size || y < 0 || y >= size) {
                System.out.println("坐标无效，请重新输入！");
                continue;
            }
            if (board[x][y] != 0) {
                System.out.println("该位置已经有棋子了，请重新输入！");
                continue;
            }
            // 在棋盘上放置棋子
            board[x][y] = turn == 0 ? player1 : player2;
            printBoard(); // 打印棋盘
            if (checkWin(x, y)) { // 检查是否胜利
                System.out.println("玩家 " + (turn == 0 ? "1" : "2") + " 胜利！");
                break;
            }
            turn = turn == 0 ? 1 : 0; // 切换玩家
        }
    }

    // 初始化棋盘
    private static void initBoard() {

            }
        }
    }

    // 打印棋盘
    private static void printBoard() {
        System.out.print(" ");
        for (int i = 0; i < size; i++) {
            System.out.print(i + 1);
        }
        System.out.println();
        for (int i = 0; i < size; i++) {
            System.out.print(i + 1);
            for (int j = 0; j < size; j++) {
                System.out.print(board[i][j]);
            }
            System.out.println();
        }
    }

    // 获取玩家输入的坐标
    private static int getPlayerInput(String coordinate) {
        System.out.print("玩家 " + (turn == 0 ? "1" : "2") + "，请输入" + coordinate + "坐标（1-" + size + "）：");
        return scanner.nextInt() - 1;
    }

    // 检查是否胜利
    private static boolean checkWin(int x, int y) {
        char player = turn == 0 ? player1 : player2;
        // 检查横向
        int count = 0;

                }
            } else {

            }
        }
        // 检查左上到右下斜线
        count = 0;
        for (int i = x, j = y; i >= 0 && j >= 0; i--, j--) {
            if (board[i][j] == player) {
                count++;

                count++;
                if (count == 5) {
                    return true;
                }
            } else {

                }
            } else {
                break;
            }
        }
        return false;
    }
}

这个五子棋代码实现了一个简单的控制台版游戏，玩家可以通过输入坐标来下棋，当有一方连成五个棋子时游戏结束。
