用Java编写一个五子棋游戏

好的，我可以为您提供一个基本的五子棋游戏的Java代码，如下所示：

import java.util.Scanner;

public class GomokuGame {

    private static final int BOARD_SIZE = 15;
    private static final char EMPTY = '-';
    private static final char BLACK = 'X';
    private static final char WHITE = 'O';

    private char[][] board;
    private char currentPlayer;

    public GomokuGame() {
        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] = EMPTY;
            }
        }
        currentPlayer = BLACK;
    }

    public void play() {
        Scanner scanner = new Scanner(System.in);
        int row, col;
        while (true) {
            System.out.println("Current player: " + currentPlayer);
            printBoard();
            System.out.print("Enter row and column (e.g. 3 4): ");
            row = scanner.nextInt();
            col = scanner.nextInt();
            if (isValidMove(row, col)) {
                board[row][col] = currentPlayer;
                if (isWinningMove(row, col)) {
                    System.out.println(currentPlayer + " wins!");
                    printBoard();
                    break;
                }
                if (isBoardFull()) {
