JAVA: Unformed Sprite When trying to Read SpriteSheet

So Im a beginner experimenting with ImageIO. Can someone tell me why im getting this pixelated-incomplete sprite?

Here's the code

public BufferedImage getImage(String location)
{
    try 
    {
        File file = new File(location);

        image = ImageIO.read(file);
    } 
    catch (IOException e) 
    {
        System.err.println("It don't work!!");
        e.printStackTrace();
    }
    return image;
}

And Im using this method to display it

public void paint(Graphics g)
{
    g.drawImage(getImage("Numbers/icon0.png"), 0, 0, 32, 32, null);
    repaint();
}

THANK YOU IN ADVANCE
