Background image not displaying in java project

Question

The variable was made, the image is loaded into the variable and the paintComponent is asked to display the image in my JPanel. I can't see my mistake.

public class Main extends JFrame {

    public static void main(String[] args) {
        JFrame frame = new Main();
        frame.setSize(1524, 715);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setTitle("Animatieproject Stijn Mannaerts: Free Kick");
        frame.setContentPane(new Voetbalveld());
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
    }
}

class Voetbalveld extends JPanel {

    private ImageIcon afbIntro;

    public Voetbalveld() {

        afbIntro = new ImageIcon("scr/afbeeldingen/Intro.jpg");

    }

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        afbIntro.paintIcon(null, g, 0, 0);

    }
}

Look through today's questions on embedded resources, it has been covered several times! — Andrew Thompson, Jan 02 '14 at 13:54

That isn't how painting is done. Why not use Graphics.drawImage() instead? Check out this tutorial: http://docs.oracle.com/javase/tutorial/uiswing/painting/

Your code seems right to me. Make sure you don't want src instead of scr. Next, if your image folder is inside source folder of your project then you might want to try this:

afbIntro = new ImageIcon(Voetbalveld.class.getResourceAsStream("scr/afbeeldingen/Intro.jpg"));

or

afbIntro = new ImageIcon(Voetbalveld.class.getResourceAsStream("afbeeldingen/Intro.jpg"));

depending on your file structure. The path in the second example needs to be relative to the file Main.java.

The frame class

    import javax.swing.JFrame;

    public class Main
    {
        public static void main(String[] args)
        {
        Jframe frame = new JFrame("Animatieproject Stijn Mannaerts: Free Kick");
        frame.setSize(1524, 715);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setContentPane(new Voetbalveld());
        frame.setVisible(true);
        }
    }

The panel class

    import javax.swing.*;
    import java.awt.*;

    public class Voetbalveld extends JPanel
    {
        public void paintComponent(Graphics g)
        {    
        ImageIcon afbIntro = new ImageIcon("scr/afbeeldingen/Intro.jpg");
        /*The following are two methods for image sizing,
         *Use the one that best fits your code:
         *
         *g.drawImage(afbIntro.getImage(), x, y, null); 
         *Fill in the arguments for x and y to locate your upper left corner
         *The image will be in it's original size with the designated upper left corner
         *
         *g.drawImage(afbIntro.getImage(), x, y, w, h, null);
         *Fill in the arguments for w and h to set the width and height of your image
         *The image will be in it's scaled size (w and h) and starting at the 
         *designated upper left corner (x and y)
         */
        }
    }

You spelled src wrong. You have scr.

"scr/afbeeldingen/Intro.jpg"

Fix that
