Othello游戏板的Java初始化

Question

我正在尝试用Java初始化Othello的游戏板。它应该提示用户输入两个播放器名称，将player 1设置为暗片，将player 2设置为亮片，但是当我试图编译时，会得到以下错误：

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: core.Disc.setColor

at core.Board.initObjects(Board.java:44) "board[3][3].setColor(Constants.LIGHT);"

at core.Board.<init>(Board.java:24) "initObjects();"

at core.Game.initObjects(Game.java:30) "board = new Board();"

at core.Game.<init>(Game.java:25) "initObjects();"

at othello.Othello.main(Othello.java:17) "Game game = new Game();"

有人能提供一些关于该做什么的见解吗？我不知道怎么回事

如果格式化不好的话很抱歉。不确定如何为多个Java类设置格式。

Board.java

package core;

// board class
public class Board {

    // member variable board (always make access modifier 'private'        
    // Disc = data type (class)
    private Disc[][] board;

    // constructor (same name as class)
    public Board(){

        // method call for initObjects
        initObjects();
    }

    private void initObjects(){

        // declaring size of array // new is used to allocate memory
        board = new Disc[Constants.ROWS][Constants.COLUMNS];

        // looping and initializing board
        for(int row = 0; row < Constants.ROWS; row++){

            for (int col = 0; col < Constants.COLUMNS; col++){

                // calling no argument constructor
                // for class Disc
                board[row][col] = new Disc();
            }
        }

        // setColor is part of class Disc
        board[3][3].setColor(Constants.LIGHT);
        board[3][4].setColor(Constants.DARK);
        board[4][3].setColor(Constants.DARK);
        board[4][4].setColor(Constants.LIGHT);

Answer 1

变量board是Disc的2D数组。

Disc没有方法setColor()

正确的方法名是setDiscColor()
