Help with buttons and graphics

Question

public class Ers2View extends FrameView{
Image image;
static Paint paint;
public Ers2View(SingleFrameApplication app) {
super(app);
initComponents();
slapButton = new javax.swing.JButton();
slapButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
slapButtonActionPerformed(evt);
private void slapButtonActionPerformed (java.awt.event.ActionEvent evt) {                                          
     Graphics g= image.getGraphics();
     Paint rect=new Paint();
     Paint.paint(g);
(new file)
package ers2;
import java.awt.Graphics;
public class Paint{
public static void paint(Graphics g) {
     g.drawRect (10, 10, 200, 200);

No i know where the problem is but i have no idea how to fix it. I think part of the problem is that I never tell it to draw on the JPanel. But Netbeans makes weird code so im not sure how to make the drawRect command implemented on the panel.>
- People about these parts comment on Java problems, not Netbeans problems. Netbeans has its own [forums for Netbeans problems|http://forums.netbeans.org/] (<- link), try them.
- As far as the Java code goes, you will get a much better chance of help if you..
a) Post an SSCCE (<- link), rather than random code snippets that you think encapsulate the problem. Let's face it, you don't know the answer, and until you do, you cannot be sure the fix is to be found in the code snippets you post. Can you?
b) Post code in between code tags to retain the formatting and indentation. To do that, select the code and click the CODE button on the Plain Text tab of the message posting form.Easy there tiger, this is not a netbeans problem, so he is in the right place.
The code does look to be SSCCE or close anyways (remove the ... lines and if it still compiles and run I would say this is SSCCE).
The code tags is a huge problem here though. I am trying to read it without getting a headache, best as I can tell the OP seems to be doing some really funny stuff with paint. Like is he overriding paint to paint a square? That can't be good!
