paintComponent method is not drawing image

I am trying to get used to using the paintComponent() method before I incorporate it into my program. However, whenever I try and draw an image to the JPanel, it is not working. I have put the code below. Any help would be appreciated. Thanks. 

public class ExperimentGame extends JPanel{

Image image;

public ExperimentGame(){
    JFrame frame = new JFrame();
    SwingUtilities.isEventDispatchThread();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(this);
    frame.pack();
    frame.setSize(500,500); //my edit
    this.setBackground(Color.WHITE);
    frame.setVisible(true);
    try {
        image = ImageIO.read(this.getClass().getResource("spaceship (0).png"));
    } 
    catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


}

public void paintComponent(Graphics g){
    super.paintComponent(g);
    g.drawImage(image, 50, 50, null);
}
}

public class ExperimentMain {

public static void main(String[] args) {
    ExperimentGame game = new ExperimentGame();
}
}

A small hack to solve your problem is to call at the bottom of your constructor.

this.revalidate();
this.repaint();

However I recommend you to take a look how Model-View-Controller can be used to update your view whenever something is changed in your model. An example can be found here.
