Comparing ImageIcons

[nubshat]

I am trying to make a matching game in java where the user flips over two images the program either disables those buttons or if the user gets it wrong the program resets the buttons.
I have most of the program working I am just having issues with comparing the images.

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.*;
import javax.swing.*;
import static java.util.Collections.*;
import javax.swing.ImageIcon.*;

public class MatchingGame extends JFrame implements ActionListener {
    private JButton exitButton, replayButton;
    private JButton[] gameButton = new JButton[36];
    private ImageIcon[] ImageArray;
    private ImageIcon[] images2;
    private int counter = 0;
    private int[] buttonID = new int[2];
    private ImageIcon[] buttonValue = new ImageIcon[2];
	
    public MatchingGame() {
    	setLayout(new BorderLayout());
    	init();
        panel();
        setImages();
        setTitle("MathingGame");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setSize(900, 900);
        setVisible(true);
    }
    
    public void init() {
        for (int i = 0; i < gameButton.length; i++) {
            gameButton[i] = new JButton();
            gameButton[i].addActionListener(this);
        }
        exitButton = new JButton("Exit");
        exitButton.addActionListener(this);
        replayButton = new JButton("Replay");
        replayButton.addActionListener(this);
    }

    	gamePanel.setLayout(new GridLayout(6, 6));

        	gamePanel.add(gameButton[i]);
    	}

                gameButton[i].setEnabled(false);
                counter++;
                if (counter == 3) {
                    if (sameValues()) {
                        gameButton[buttonID[0]].setEnabled(false);
                        gameButton[buttonID[1]].setEnabled(false);
                    } else {
                        gameButton[buttonID[0]].setEnabled(true);
                        gameButton[buttonID[0]].setIcon(null);
                        gameButton[buttonID[1]].setEnabled(true);
                        gameButton[buttonID[1]].setIcon(null);

            }
    	}
		if (exitButton == e.getSource()) {
		    System.exit(0);

			setImages();
		}
    }
    
    public static void main (String[] args){
    	new MatchingGame();
    }
    
}

What I have right now is not working. I have also tried:

    
public boolean sameValues() {
    	if (buttonValue[0].toString().equals(buttonValue[1].toString())){
    		return true
        }
        return false;
    }

Please help me.

How about comparing the references to the icons shown by the two buttons? JButton has a method that returns a reference to the icon it is showing.

How would I do that?

Get the references to the icons for each button and use the == operator to see if they are the same.
