Hi I am working on creating a tower Defence java applet game and have come to a road block about implementing a title screen that i can select the level and difficulty of the rest of the game. my title screen class is called Menu. from this menu class i need to pass in many different variables into my Main class.

i have used different classes before and know how to run them and such. but if both classes extend applet and each has its individual graphics method how can i run things from Main even though it was created in Menu.

what i essentially want to do is run the Menu class withits action listeners and graphics until a Difficulty button has been selected, run the main class (which 100% works without having to have the Menu class) and pretty much terminate Menu so that i cannot go back to it, do not see its buttons or graphics menus. can i run one applet annd when i choose a button close that one and launch the other one?

IF you would like to download the full project you can find it here, i had to comment out all the code that wasn't working

my Menu class

import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class Menu extends Applet implements ActionListener{

 Button bEasy,bMed,bHard;
    Main m;

    public void init(){

        bEasy= new Button("Easy");  bEasy.setBounds(140,200,100,50);    add(bEasy); 
        bMed = new Button("Medium");bMed.setBounds(280,200,100,50); add(bMed);  
        bHard= new Button("Hard");bHard.setBounds(420,200,100,50);  add(bHard); 
        setLayout(null);
    }
    public void actionPerformed(ActionEvent e){
        Main m = new Main(20,10,3000,mapMed);//break;
        switch (e.getSource()){


            case bEasy: Main m = new Main(6000,20,"levels/levelEasy.png");break;//enimies tower money world
            case bMed:  Main m = new Main(4000,15,"levels/levelMed.png");break;
            case bHard: Main m = new Main(2000,10,"levels/levelEasy.png");break;
        default: break;
        }
    }
    public void paint(){
    //m.draw(g)
    }
}

and here is my main class initialising code.
