用java语言写出五子棋的代码

好的，下面是五子棋的Java代码：

import java.util.Scanner;

public class Gobang {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int[][] board = new int[15][15];
        int player = 1;
        boolean win = false;

        while (!win) {
            System.out.println("请输入玩家" + player + "的下棋位置（行 列，以空格隔开）：");
            int row = sc.nextInt();
            int col = sc.nextInt();

            if (board[row][col] != 0) {
                System.out.println("该位置已经有棋子，请重新输入！");
                continue;
            }

            board[row][col] = player;
            printBoard(board);

            if (checkWin(board, row, col, player)) {
                System.out.println("恭喜玩家" + player + "获胜！");
                win = true;
            }

            player = 3 - player;
        }
    }

    public static boolean checkWin(int[][] board, int row, int col, int player) {
        int count = 1;

        // 检查行
        for (int i = col - 1; i >= 0 && board[row][i] == player; i--) {
            count++;
        }
        for (int i = col + 1; i < 15 && board[row][i] == player; i++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }

        // 检查列
        count = 1;
        for (int i = row - 1; i >= 0 && board[i][col] == player; i--) {
            count++;
        }
        for (int i = row + 1; i < 15 && board[i][col] == player; i++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }

        // 检查左上到右下的对角线
        count = 1;
        for (int i = row - 1, j = col - 1; i >= 0 && j >= 0 && board[i][j] == player; i--, j--) {
            count++;
        }
        for (int i = row + 1, j = col + 1; i < 15 && j < 15 && board[i][j] == player; i++, j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }

        // 检查左下到右上的对角线
        count = 1;
        for (int i = row + 1, j = col - 1; i < 15 && j >= 0 && board[i][j] == player; i++, j--) {
            count++;
        }
        for (int i = row - 1, j = col + 1; i >= 0 && j < 15 && board[i][j] == player; i--, j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }

        return false;
    }

    public static void printBoard(int[][] board) {
        for (int i = 0; i < 15; i++) {
            for (int j = 0; j < 15; j++) {
                System.out.print(board[i][j] + " ");
            }
            System.out.println();
        }
    }
}

这个程序实现了一个简单的五子棋游戏，玩家可以输入棋子的位置，程序会检查是否有获胜的情况出现。具体实现可以参考代码中的注释。
