java - 两个带有网格的 JFrame 在一个类中

Question

我正在尝试编写一个战舰游戏，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，为每次生成新变量，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。有什么指示吗？

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 class BatShip3 extends JFrame implements ActionListener{


    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);
                   panel.setBackground(Color.black);

                   for(int rows = 0; rows <100 ; rows++){
                      for(int cols = 0; cols < 100 ; cols++){
                          buttons [rows][cols] = new JButton ();
                          buttons [rows][cols].setBackground(Color.blue);
                          buttons [rows][cols].addActionListener(this);
                          panel.add(buttons [rows][cols]);
                      }     
                   }
                   contentArea.add(panel);
                   window1.setContentPane(contentArea);
    }        


      JFrame window2 = new JFrame("Window 2");{
           window2.setSize (800, 600);
           window2.setVisible (true);
           window2.setBackground (Color.black);
           window2.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

           canvas = new JPanel();
           GridLayout experimentLayout2 = new GridLayout(100, 100);
           canvas.setLayout (experimentLayout2);
           canvas.setBackground(Color.black);

             for(int rows1 = 0; rows1 <100 ; rows1++){
                 for(int cols1 = 0; cols1 < 100 ; cols1++){
                     clicks [rows1][cols1] = new JButton ();
                     clicks [rows1][cols1].setBackground(Color.blue);
                     clicks [rows1][cols1].addActionListener(this);
                     canvas.add(clicks [rows1][cols1]);
                 }     
             }
              contentArea2.add(canvas);
              window2.setContentPane(contentArea2);
              }
              }
    public void actionPerformed(ActionEvent ev){

        for(int rows = 0; rows < 100 ; rows++){
            for(int cols = 0 ; cols < 100 ; cols++){
                 if(ev.getSource() == buttons [rows][cols]){            
                      buttons[rows][cols].setBackground(Color.green);
                 }
            }
        }
        for(int rows1 = 0; rows1 < 100 ; rows1++){
            for(int cols1 = 0 ; cols1 < 100 ; cols1++){
                if(ev.getSource() == clicks [rows1][cols1]){

                   clicks[rows1][cols1].setBackground(Color.green);
                 }
            }
        }
}}

定义描述战舰游戏的模型类。这是我几分钟后的想法。

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 View 类。 JPanel 绘制模型类。

为玩家 1 创建一个 JFrame View 类实例，并为玩家 2 创建另一个实例。
