Icon not showing when jar file is run

I'm a beginner in Java and I followed a tutorial to write this program (yes, I that much of a beginner) and it works perfectly when I run it on Eclipse. It also runs great on the computer I coded it on. However, if I send it to another computer (just the .jar file) and run it, it fails because it can't find the icon. Here is everything I've got. The icon I'm using is saved in the bin folder along with all the class files for the program. For privacy reasons, I replaced certain lines with "WORDS".

The tutorial I followed in two parts:

Part 1 - https://buckysroom.org/videos.php?cat=31&video=18027

Part 2 - https://buckysroom.org/videos.php?cat=31&video=18028

My main class (I called it apples cause the tutorial did).

import javax.swing.JFrame;

public class apples {
public static void main(String[] args) {
Gui go = new Gui();
go.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
go.setSize(1920,1080);
go.setVisible(true);
}
}

And now my second class, "Gui":

import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;

public class Gui extends JFrame {

private JButton custom;

public Gui () {
    super("WORDS");
    setLayout(new FlowLayout());

    Icon b = new ImageIcon(getClass().getResource("b.png"));
    custom = new JButton(null, b);
    custom.setToolTipText("WORDS");
    add(custom);

    HandlerClass handler = new HandlerClass();
    custom.addActionListener(handler);
}

private class HandlerClass implements ActionListener {
    public void actionPerformed(ActionEvent event) {
        JOptionPane.showMessageDialog(null, String.format("WORDS", event.getActionCommand()));
        JOptionPane.showMessageDialog(null, String.format("WORDS", event.getActionCommand()));
        JOptionPane.showMessageDialog(null, String.format("WORDS", event.getActionCommand()));
        JOptionPane.showMessageDialog(null, String.format("WORDS", event.getActionCommand()));
    }
}
}

Thank you so much for helping!

It's worth reading Loading Images Using getResource where it's explained in detail along with loading images from jar as well.

You can try any one based on image location.

// Read from same package 
ImageIO.read(getClass().getResourceAsStream("b.png"));

// Read from src/images folder
ImageIO.read(getClass().getResource("/images/b.png"))

// Read from src/images folder
ImageIO.read(getClass().getResourceAsStream("/images/b.png"))
