井字游戏没有输出？

Question

目前在java做井字游戏的学校项目，感觉代码本身是正确的，但是当我尝试输出时，它不会执行打印功能并一直显示获胜者，也打印函数本身在分配给这些函数时不会输出 BLANK、CROSS 或 NAUGHT。任何帮助将不胜感激

    public static void printBoard(char[][] board)
    {
        for(int i=0;i<NUMBER_OF_ROWS;i++)

            {

                {
                    System.out.print("| ");
                }

Answer 1

你的isBoardFull方法中i>NUMBER_OF_ROWS和j>NUMBER_OF_COLUMNS条件不对，应该是其他方式。因此它总是 return true 即板已满
