How to use a JButton to display another form

Question

Hello.
I am using Netbeans 6.5 to autogenerate a GUI. I have generated 2 separate forms, one is called MainMenu.java and the second is called subMenu.java.
How do I do it so that when you click the start button (jButton1) in the main menu (MainMenu.java) it displays the submenu (subMenu.java).
Here is the code as follows:
//MainMenu.java
public class MainMenu extends javax.swing.JApplet {
    /** Initializes the applet MainMenu */
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    initComponents();
        } catch (Exception ex) {
            ex.printStackTrace();
//Generated Code
    private void initComponents() {
        jButton1 = new javax.swing.JButton();
        jButton2 = new javax.swing.JButton();
        jButton1.setText("Start");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
        jButton2.setText("Exit");
        jButton2.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton2ActionPerformed(evt);
    }// </editor-fold>
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
        System.exit(0);
    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JButton jButton2;
    // End of variables declaration
//subMenu.java
  public class subMenu extends javax.swing.JFrame {
    /** Creates new form subMenu */
    public subMenu() {
        initComponents();
//Generated Code
       private void initComponents() {
        jButton1 = new javax.swing.JButton();
        jButton2 = new javax.swing.JButton();
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        jButton1.setText("Level 1");
        jButton1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
        jButton2.setText("Level 2");
        jButton2.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton2ActionPerformed(evt);
           }// </editor-fold>
    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
    private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
    * @param args the command line arguments
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new subMenu().setVisible(true);
    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JButton jButton2;
    // End of variables declaration
}

I asked my question in hopes that somebody has maybe had a similar question or has dealtwith something similar to what I am trying to do
But you said you already know how to do this. You said you know how to create a JFrame and display it. So what is your problem?
You said you know where to add the code. So again what is your problem?
All you posted is code that was generated by the IDE. You have not make any effort to add your own code. Why do you think the code to show a frame here, is any different than the code you used to show a frame in the past?
You learn by trying, not by asking people to spoon feed the answer to you.
If you would even make the slightest effort at filling in the code where the IDE has told you to add the code I would be more willing to help. But apparently you have no desire to make the effort.
