Java编写五子棋游戏代码

非常感谢您的提问，以下是 Java 编写五子棋游戏代码的示例：

import java.util.Scanner;

public class Gobang {
    private static final int BOARD_SIZE = 15;
    private String[][] board = new String[BOARD_SIZE][BOARD_SIZE];
    private String player1;
    private String player2;

        this.player1 = player1;
        this.player2 = player2;
        initBoard();
    }
