java - 如何修复 'Method is undefined for type'错误

Question

我正在尝试实现一种替换二维数组中的元素之一的方法

public class GameBoard {

    public static final char EMPTY = '.';
    public static final char PLAYER1 = 'X';
    public static final char PLAYER2 = 'O';

    public static final int ROWS = 6;
    public static final int COLUMNS = 7;
    private char[][] board;
    public char[][] getBoard(){
         return board;
    }
    public char[][] get_move( int move, char player) {
         char[][] x = getBoard();
         if (player == PLAYER1 || player == PLAYER2) {
             for (int row = 0; row<ROWS; row++) {
                 if (x[row][move] == EMPTY) {
                         x[row][move] = player;
                         return x;
                 }
             }
         }
         else {
             return board;
         }
         return getBoard();

   }

  public static GameBoard setBoardForTest(int[] moves, GameBoard board){
      char player = PLAYER1;
      for(int move: moves){


          board.getMove(move, player);

          if(player == PLAYER1){
              player = PLAYER2;
          }
          else{
              player = PLAYER1;
          }
      }
      return board; 
 }

但是，当我在 setBoardForTest() 方法中调用 board.getMove(player,move) 时，我不断收到错误，该方法 getMove(int, char) 对于 GameBoard 类型未定义

Answer 1

您定义了方法get_move，而不是getMove。只需重命名它就可以了。
