Loading an image and then using it as a background

[ResidentBiscuit]

Hey all so I am attempting to load an image and use it as a background for a 2d game I've made for my Java course. Here is what I have, and it is not working. No image is being loaded/displayed

img = Toolkit.getDefaultToolkit().getImage(getClass().getResource("mario.jpg"));

public void drawBackground(Graphics graphics)
    {
    	graphics.drawImage(img, 0, 0, this);
    }

I don't see what the issue is here, but then again I dont have much experience in writing graphics. Thanks in advance!

You don't draw images like that, but rather than us re-write a chapter, your best bet is to find the graphics tutorials and read them before trying to do this stuff.
