How to fix a JOptionPane that spams messages?

Question

so I created this program and it was working perfectly fine before, however after transferring computers, my program is exploding. The JOptionPane is being spammed and completely running ram pate. If you could please run this program and tell me what is wrong, it would be much appreciated. The program is supposed to create a bingo card on a JFrame.

package Bingopackage;



import javax.swing*;

import java.awt.*;

import java.awt.event.*;

import java.awt.AWTEvent;


public class BingoCard extends JComponent {


    public void paintComponent(Graphics g)

Answer 1

Start by taking reading Performing Custom Painting and Painting in AWT and Swing so you can understanding how painting is done in Swing.

Next, remove EVERYTHING NOT not directly related to painting your component from its paintComponent method

Swing is an event driven environment, this means that something happens and you respond to it. Swing will repaint you component for any number of reasons, many of which you don't control.

Take a look at How to create a GUI with Swing for more details
