Java 将数组作为参数传递-棋盘

我看不出有什么不对，我正在尝试传递gameBoard数组，这不是数组吗？-请参阅FindPice方法中的构造函数，但它会这样说 这不是一个数组，我应该在这里传递什么来获得未更新的板？对不起，我是编程新手，但我真的很感激任何提示

public class Game {



    private Board gameBoard;



    public Game() {
        gameBoard = new Board();
    }


    public void play(Board board) {

        EasyIn2 reader = new EasyIn2();

        gameBoard = new Board();     //initializes the board so dont need to do so in main

        boolean done = false;

        while(!done) {                     //keeps looping when no one has won yet
            gameBoard.printBoard();

            System.out.println(WHITEPLAYS_MSG);

            String pos1 = reader.getString();         //gets user input ... move from... to....   temporary variables
            int xFrom=pos1.charAt(0) - 'a';                           //to transform the letter
            int yFrom=pos1.charAt(1) - '1';                           // to transform the number

            String pos2 = reader.getString();
            int xTo=pos2.charAt(0) - 'a';                           //to transform the letter
            int yTo=pos2.charAt(1) - '1';                           // to transform the number

            gameBoard.findPiece(gameBoard,xFrom,yFrom);


}
}
}

你应该通过gameBoard.board:实际上，你正在通过该类gameBoard的整个实例，而不仅仅是它的数组组件。因此，这是对的：你被告知没有通过数组的错误。

FindPice需要一个char[][]作为第一个参数，而不是整个类板。

您需要调用findPiece方法，第一个参数为gameBoard.board；

findPiece需要一个char[][]作为第一个参数，而不是整个类板。 您需要使用第一个参数gameBoard.board调用findPiece方法
