Paint Component Method not working for JFrame

I'm trying to paint an image on the screen after trying to use JLabel's and am now trying the paintComponent method. I tried inserting breakpoints after seeing no results and the method doesn't get called, and nothing appears. What should I do? Here is my important code-

`

     public void createWindow(){        

            frame.setVisible(true);  
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLocationRelativeTo(null);
    frame.pack();
    frame.setSize(xSize, ySize);
            frame.setLocation(0, 0);
            frame.addComponentListener(this);
            //frame.add(im);             

    }

public void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(placeholder, 0, 0, getWidth(), getHeight(), null); g.drawString("Hello", 100, 100); }

Also I'm using a JFrame instead of JPanel or component if that makes a difference.

JFrame does not have a paintComponent method. You should avoid painting directly to a frame and instead use a JPanel and override its paintComponent method

You should also make use of the @Override annotation, which will raise a compiler exception if the parent class does not have the method you are trying to override...
