How to draw different objects with paintComponent()?

I am trying to draw several things inside a JPanel. I am drawing shapes (works), and I also want to fill the JPanel with a picture. But paintComponent() only takes one argument. And this gets complicated when I have some extra code for drawing the shapes.

My paintComponent() method is currently like this:

public void paintComponent(Graphics g) {


    g2 = (Graphics2D) g;
    for (int i = 0; i < shapes.size(); i++) {
        Shape s = (Shape) shapes.get(i);
        if (s != null)
            g2.draw(s);
    }
}

I have searched around a lot and cannot find a way to do this.

Does anyone know how to do this, or maybe some workaround?

Just like your approach to drawing shapes, you need to maintain a reference to the images you want to draw within the class and reference them in much the same way.

The following are all examples of drawing images within paintComponent, on a verity of topics

Nb - I may be misreading this, but you should never be calling paintComponent yourself. It is called on your behalf by the repaint engine within Swing
