java简易五子棋代码

以下是一个简易的 Java 五子棋代码，实现了基本的落子、胜负判断和重新开始等功能：

import java.util.Scanner;

public class Gobang {
    private static final int ROWS = 15; // 棋盘行数
    private static final int COLS = 15; // 棋盘列数
    private static final int WIN_COUNT = 5; // 获胜所需连续棋子数
    private static char[][] board = new char[ROWS][COLS]; // 棋盘数组
    private static Scanner scanner = new Scanner(System.in); // 读取用户输入的 Scanner

    // 初始化棋盘
    private static void initBoard() {
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                board[i][j] = '+';
            }
        }
    }

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

    // 判断是否获胜
    private static boolean isWin(char player) {
        // 水平方向
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j <= COLS - WIN_COUNT; j++) {
                boolean flag = true;
                for (int k = j; k < j + WIN_COUNT; k++) {
                    if (board[i][k] != player) {
                        flag = false;
                        break;
                    }
                }
                if (flag) {
                    return true;
                }
            }
        }
        // 竖直方向
        for (int i = 0; i <= ROWS - WIN_COUNT; i++) {
            for (int j = 0; j < COLS; j++) {
                boolean flag = true;
                for (int k = i; k < i + WIN_COUNT; k++) {
                    if (board[k][j] != player) {
                        flag = false;
                        break;
                    }
                }
                if (flag) {
                    return true;
                }
            }
        }
        // 左上到右下斜方向
        for (int i = 0; i <= ROWS - WIN_COUNT; i++) {
            for (int j = 0; j <= COLS - WIN_COUNT; j++) {
                boolean flag = true;
                for (int k = 0; k < WIN_COUNT; k++) {
                    if (board[i + k][j + k] != player) {
                        flag = false;
                        break;
                    }
                }
                if (flag) {
                    return true;
                }
            }
        }
        // 右上到左下斜方向
        for (int i = 0; i <= ROWS - WIN_COUNT; i++) {
            for (int j = WIN_COUNT - 1; j < COLS; j++) {
                boolean flag = true;
                for (int k = 0; k < WIN_COUNT; k++) {

                    return true;
                }
            }
        }
        return false;
    }

    public static void main(String[] args) {
        initBoard(); // 初始化棋盘
        char currentPlayer = 'X'; // 当前玩家（X 或 O）
        printBoard(); // 打印棋盘

        while (true) {
            System.out.print("请输入 " + currentPlayer + " 的落子位置（如：5,7）：");
            String input = scanner.nextLine();
            int row = Integer.parseInt(input.split(",")[0]) - 1;
            int col = Integer.parseInt(input.split(",")[1]) - 1;
            if (board[row][col] != '+') {
                System.out.println("此位置已经有棋子，请重新输入！");
                continue;
            }
            board[row][col] = currentPlayer;
            printBoard();
            if (isWin(currentPlayer)) {
                System.out.println(currentPlayer + " 获胜！");
                break;
            }
            if (currentPlayer == 'X') {
                currentPlayer = 'O';
            } else {

        scanner.close();
