Sharing information between midlet and classes

Question

I'm new to this J2ME language and this question might be stupid, but here it goes.
As I am creating a program that will have a s**t load of code, I am trying to use 1 midlet and then the rest as classes. The problem where I am stuck is that how can i share information between these.
Can someone give me a simple example where there is a midlet and a class. For example, the midlet displays the main menu and the class displays the submenu..
If someone could help me, I would appreciate it a lot.

Hi again!
Maybe I confused a little bit with the question, here is my sample code and I have added in the code the parts where I am confused.
The program should get the submenu from the subMenu class and display it
Where should these files be placed and named? should they both be java files and places in the src folder or should the Info class be named just class and placed inside the classes folder???
--------------------------------------------------------mainMenu.java---------------------------------------------
package Menus;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class mainMenu extends MIDlet implements CommandListener
private Display display;
private List menu;
private Command coNext;
private sub subMenu;
public mainMenu()
display = Display.getDisplay(this);
String strv[] = {"Info"};
menu = new List("mainMenu", List.IMPLICIT, strv, null);
coNext = new Command("Next", Command.OK, 1);
protected void destroyApp(boolean p0)
protected void pauseApp()
protected void startApp() throws MIDletStateChangeException
menu.addCommand(coNext);
menu.setCommandListener(this);
display.setCurrent(menu);
public void commandAction(Command c, Displayable dp)
if(dp==menu && (c==menu.SELECT_COMMAND || c==coNext))
sub = new subMenu(this);
if(menu.getSelectedIndex()==1)
Info. <------------WHAT COMES HERE??????
else
this.notifyDestroyed();
this.destroyApp(false);
display.setCurrent(Info);
sub.start();
else
display.setCurrent(this);
--------------------------------------------------END OF mainMenu.java------------------------------------------------------
---------------------------------------------------subMenu.class or java ????-----------------------------------
package Menus;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class subMenu extends mainMenu implements commandListener
private mainMenu main;;
private Display display;
private List menu;
private Command coBack;
public subMenu()
display = Display.getDisplay(this);
String strv[] = {"Welcome"};
menu = new List("SubMenu", List.IMPLICIT, strv, null);
coNext = new Command("Back", Command.OK, 1);
public void public void commandAction(Command c, Displayable dp)
WHAT COMES AFTER THIS????
