Probably simple...

[Chippy]

Hello there. Just starting off in Java, I have experience in other languages, and have read a Java book (and then forgot most of it).

Anyways, I simply cannot figure out why this program won't work properly. When I try to execute it, it just closes before actually starting, but after compiling.

Here's what I'm trying to do:
Make a window with 2 panels, each with their own tabs.

Right now tab2, called content, is just plain and is using nothign special, to be changed once I get the first one to work.

If you have any other questions feel free to ask. Thanks in advance, and check the source code attached.

Note: I've made it a JApplet, after all, you were using swing components
inside an awt component and that is not a recommended practise...

// our imports
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class GUIBreasts
    extends JApplet {
  // creates the border
  BorderLayout myLayout = new BorderLayout();

  // right now this is static, well change after we get menu working
  Panel content = new Panel();

  // our menu
  private JTabbedPane menu;

  // our menu tabs
  //private Panel System; /// <======== NOOOOOO ! System is a java.lang basic 
                         // class, and you don't want to 'disable' it like this, 
                         // no way...

  private Panel ASystem;
  private Panel Games;
  private Panel Apps;


  /**
   * An applet constructor is useless, the browser will use the basic
   * parameterless constructor no matter what you do,  so the init()
   * method may be regarded as *the* applet constructor
   */
  public void init() { // <========= autoinvoked by browser after instantiation
    // sets the size... duh
    setSize(300, 200);

    // creates the panel
    Panel topPanel = new Panel();
    // sets the layout
    topPanel.setLayout(myLayout);
    // and then adds it
    add(topPanel);

    // adds a button to content as a control type thing
    content.add(new Button("Test2"));

    // setting up our menu
    addMenu();

    //add out 2 panels
    topPanel.add(menu, BorderLayout.WEST);
    topPanel.add(content, BorderLayout.CENTER);

  }

  public void addMenu() {
    // makes our menu tab
    menu = new JTabbedPane();

    // makes our first tab
    ASystem = new Panel();
    ASystem.add(new Button("Games"));
    menu.addTab("System", null, ASystem, "System");

    // and our second tab
    Panel Games = new Panel();
    Games.add(new Button("Games"));
    menu.addTab("Games", null, Games, "Games");

    // and third
    Panel Apps = new Panel();
    Apps.add(new Button("Applications"));
    menu.addTab("Applications", null, Apps, "Applications");

  }

  public static void main(String[] args) {
    // creates a type of this
    GUIBreasts gui = new GUIBreasts();
    Frame f=new Frame("Breasts ...! (pant! pant! pant!)");
    f.setLayout(new GridLayout());
    gui.init(); // no browser in this mode.... must do init() "manually"
    f.add(gui);
