初始化棋盘游戏网格Java

基本上，我正在努力为我正在创建的棋盘游戏创建网格。基本上我有两种类型的棋子，勇士和草（草是静止的）。战士类有战士的子类，如忍者等

电路板上的每一块都有一个唯一的char值，该值将显示在电路板的输出中，如图所示

以下是我的课程：

package me.sample;

import java.awt.*;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class Grid {

    private static char[][] boardArray;
    private int mRow;
    private int mCol;
    private int mIterations;


    public Grid_23722002(int row, int col, ArrayList<Warrior_23722002> warList, ArrayList<Grass> grassList, char[][] array) {


        


    }


    public static void displayGrid(Grid_23722002 grid) {

        for (int i = 0; i < grid.getRow(); i++) {

            for (int j = 0; j < grid.getCol(); j++) {

                System.out.println(boardArray[i][j]);

            }


        }


    }

    public int getRow() {

        return mRow;

    }

    public int getCol() {

        return mCol;
    }

}

目前，我已经在主类中使用适当的对象定义了两个ArrayList，一个用于战士，一个用于草地。下面是我初始化不同列表的示例。这只是一个代码片段，完整的代码包含了所有不同类型的战士

else if (list.get(i).contains("Ninja")) {

                    NinjaWarrior n = new NinjaWarrior();
                    final String[] attributes = list.get(i).split(" ");
                    setWarriorAttributes(n, attributes);
                    warriorList.add(n);

                }

                else if (list.get(i).contains("Grass") && !(list.get(i).length() > 8)){

                    int counter = 1;

                    while(!(list.get(i+counter).isEmpty())){  

                        final String[] attributes = list.get(i+counter).split(" ");
                        Grass g = new Grass();
                        g.setRow(Integer.parseInt(attributes[0]));
                        g.setCol(Integer.parseInt(attributes[1]));

                        grassList.add(w);
                        counter++;

                    }

                }

接下来的问题是，我如何初始化网格，使其成为如下形式，以便在需要时打印它

package me.sample;

public class NinjaWarrior extends Warrior implements WarriorInterface, PieceInterface{

    private String mType = "Ninja";
    private final char CHAR = 'N';


    public NinjaWarrior() {

    }

    public String getType(){

        return mType;

    }

    public void performSpecialAbility() {
    }

    public void specialAbilityCompleted() {
    }

    @Override
    public char getChar() {
        return CHAR;
    }

    @Override
    public String getPieceType() {
        return null;
    }
}

package me.sample;

public class Grass extends Piece implements PieceInterface {

    private final char CHAR = 'g';

    public Grass() {




    }


    @Override
    public char getChar() {
        return CHAR;
    }

    @Override
    public String getPieceType() {
        return null;
    }
}

else if (list.get(i).contains("Ninja")) {

                    NinjaWarrior n = new NinjaWarrior();
                    final String[] attributes = list.get(i).split(" ");
                    setWarriorAttributes(n, attributes);
                    warriorList.add(n);

                }

                else if (list.get(i).contains("Grass") && !(list.get(i).length() > 8)){

                    int counter = 1;

                    while(!(list.get(i+counter).isEmpty())){  

                        final String[] attributes = list.get(i+counter).split(" ");
                        Grass g = new Grass();
                        g.setRow(Integer.parseInt(attributes[0]));
                        g.setCol(Integer.parseInt(attributes[1]));

                        grassList.add(w);
                        counter++;

                    }

                }
