Question

I have created a 3x3 memory game with colors. The program runs and displays the colors, but the JMenuBar is not working correctly. The button new board, play and end game are not working. Is there something wrong with my Actionlistener?

This is how the code should be working : https://gyazo.com/9bf3e073a9c455e56d9b4403586bfaf5?fbclid=IwAR3Zk1BZvRj49CtAz01h95zic8tk74UmyUcU2HrY3VY8XcARoD14Ke6tcoQ

This is StartPlayer

import gui.MemoryGameWindow;
import gui.ColoredPanel;
import gui.GamePanel;

public class StartPlayer {
  public static void main(String[] args) {
  new MemoryGameWindow();
  
}
}

This is ColoredPanel

package gui;

import java.awt.Color;
import java.awt.event.MouseListener;
import javax.swing.JPanel;

public class ColoredPanel extends JPanel {
  private Color thisColor = null;
  
  private Color challenge = null;
  
  public ColoredPanel(Color color) {
    this.thisColor = color;
    setBackground(color);
  }
  
  public void setGameMode(Color c, MouseListener ml) {
    setBackground(Color.LIGHT_GRAY);
    this.challenge = c;
    System.out.println("Coloredpanel says challenge is " + this.challenge);
    addMouseListener(ml);
  }
  
  public void restoreBackground() {
    setBackground(this.thisColor);
  }
}

This is GamePanel

package gui;

import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.util.Random;
import javax.swing.JLabel;

public class GamePanel extends JPanel {
  private Color[] colors = new Color[] { Color.GREEN, Color.YELLOW, Color.MAGENTA };
  
  private Random r = new Random();
  
  private int square = 9;
  
  private Color challenge;
  
  private int countOfPossibleHits = 0;
  
  private int countOfWinnerHits = 0;
  
  private JPanel challengeDisplay;
  
  public GamePanel(JPanel cd) {
    this.challengeDisplay = cd;
    setLayout(new GridLayout(3, 0, 2, 2));
    for (int i = 0; i < this.square; i++)
      add(new ColoredPanel(this.colors[this.r.nextInt(this.colors.length)])); 
  }
  
  public Color startGame() {
    Color[] existingColors = new Color[getComponentCount()];
    int i;
    for (i = 0; i < getComponentCount(); i++)
      existingColors[i] = ((ColoredPanel)getComponent(i)).getBackground(); 
    this.challenge = existingColors[this.r.nextInt(existingColors.length)];
    this.countOfPossibleHits = 0;
    for (i = 0; i < getComponentCount(); i++) {
      if (((ColoredPanel)getComponent(i)).getBackground() == this.challenge)
        this.countOfPossibleHits++; 
    } 
    for (i = 0; i < getComponentCount(); i++)
      ((ColoredPanel)getComponent(i)).setGameMode(this.challenge, new TheMouselistener()); 
    return this.challenge;
  }
  
  class TheMouselistener extends MouseAdapter {
    public void mousePressed(MouseEvent e) {
      ColoredPanel clickedObject = (ColoredPanel)e.getSource();
      clickedObject.restoreBackground();
      if (clickedObject.getBackground() != GamePanel.this.challenge) {
        clickedObject.add(new JLabel("Game Over!"));
        GamePanel.this.challengeDisplay.add(new JLabel("Game Over!"));
        System.out.println("Game Over");
        GamePanel.this.updateUI();
      } else {
        GamePanel.this.countOfWinnerHits = GamePanel.this.countOfWinnerHits + 1;
        if (GamePanel.this.countOfWinnerHits == GamePanel.this.countOfPossibleHits) {
          clickedObject.add(new JLabel("You won!"));
          GamePanel.this.challengeDisplay.add(new JLabel("You Won!"));
          GamePanel.this.updateUI();
        } 
      } 
    }
  }
}
