我正在尝试编写战舰游戏，并使用 if 语句调用 BatShip3 类，该类将生成两个带有可单击网格的 JFrame，用于放置战舰。我已经尝试在该方法中实现我的代码两次，为每个生成新变量，但我似乎无法弄清楚出了什么问题。当我选择游戏模式时，它会创建两个窗口，给它们两个黑色背景，但第二个窗口上没有网格。任何指针？

package batship2;

import java.awt.Color;
import java.awt.Container;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

    public JButton buttons [][] = new JButton [100][100];
    public JPanel panel;
    public JButton clicks [][] = new JButton [100][100];
    public JPanel canvas;
    Container contentArea = getContentPane ();
    Container contentArea2 = getContentPane ();

    public void BatShip3(){
            JFrame window1 = new JFrame("Window 1");{
                   setSize (800, 600);
                   setVisible (true);
                   setBackground (Color.black);
                   setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

                   panel = new JPanel();
                   GridLayout experimentLayout = new GridLayout(100, 100);
                   panel.setLayout (experimentLayout);

定义描述战舰游戏的模型类。这是我几分钟后想到的。

package com.ggl.battleship.model;

import java.util.List;

public class BattleshipGame {
    private int numberOfPlayers;
    private int widthOfBattleshipGrid;
    private List<BattleshipGrid> grids;
}

.

package com.ggl.battleship.model;

import java.util.List;

public class BattleshipGrid {
    private List<Ship> ships;
    private Cell[][] grid;
}

.

package com.ggl.battleship.model;

import java.awt.Point;
import java.util.List;

public class Ship {
    private int length;
    private String name;
    private List<Point> cellLocations;
}

.

package com.ggl.battleship.model;

import java.awt.Point;

public class Cell {
    private boolean isHit;
    private Point coordinates;
}

您可以创建所有适当的 getter、setter 和绘图方法。

定义一个或多个创建 JFrame 和 JPanel 的视图类。JPanel 绘制模型类。

为播放器 1 创建 JFrame 视图类的一个实例，为播放器 2 创建另一个实例。
