Stand O' Food Game Proyect

Hi!!
Well Im going to tell you what Im doing
In the university give me a task, to make a game in Java (lenguage Im learning)
I choose the Stand O' Food
http://www.alawar.com/games_img/game...creenshot2.jpg

As you can see is and ambitious proyect to me, but I want to try.
The idea of the proyect is to make the game and olso with thread make a step by step tutorial
To beging my first step is to make the backgruond of the game and thats were the problems starts, because i dont know how to putit
what i have is this..

import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
public class StandOFood{
public static final int WIDTH = 1026;
public static final int HEIGHT = 757;

public StandOFood() {
JFrame ventana = new JFrame("Stand O' Foof");
ventana.setBounds(0,0,WIDTH,HEIGHT);
ventana.setVisible(true);
ventana.addWindowListener( new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
public static void main(String[] args) {
StandOFood inv = new StandOFood();
}
}

So the cuestion is.. how can i put a background image that i attach on my screen??

THX!!!! very much!!

The general idea is to draw it on the background of your contentPane.

Code:

---

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.*;

public class StandOFoodRx {
    public static final int WIDTH = 1026;
    public static final int HEIGHT = 757;

    public StandOFoodRx() {
        JFrame ventana = new JFrame("Stand O' Foof");
        ventana.setContentPane(getContentPane());
        ventana.setBounds(0,0,WIDTH,HEIGHT);
        ventana.setVisible(true);
        ventana.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    private JComponent getContentPane() {
        // Image file must be in your classpath.
        // Here it's in the current directory.
        BufferedImage image = getImage("stand-o-food-screenshot2.jpg");
        ImageBackground cp = new ImageBackground(image);
        cp.setLayout(new BorderLayout());
        // contentPanes must be opaque.
        cp.setOpaque(true);
        return cp;
    }

    private BufferedImage getImage(String path) {
        BufferedImage image = null;
        try {
            java.net.URL url = getClass().getResource(path);
            System.out.println("url = " + url);
            image = ImageIO.read(url);
        } catch(IOException e) {
            System.out.println("read error: " + e.getMessage());
        }
        return image;
    }

    public static void main(String[] args) {
        StandOFoodRx inv = new StandOFoodRx();
    }
}

class ImageBackground extends JPanel {
    BufferedImage image;

    ImageBackground(BufferedImage image) {
        this.image = image;
    }

    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        int x = (getWidth() - image.getWidth())/2;
        int y = (getHeight() - image.getHeight())/2;
        g.drawImage(image, x, y, this);
    }
}
