Calling a method in a subclass?

Question

Hi, anyone an idea why method getInit() (in Applet class) isn't recognised in class Map?
import java.awt.*;
import java.awt.Color;
import java.awt.event.*;
import java.applet.*;
import java.util.*;
import javax.swing.*;
public class Main extends Applet {
     public boolean initialized =true;
     Map map;
     World world = new World();
     public void init()
          Map = new map("map.jpg",0,0,world,this);
     public boolean getInit()
     { return initialized; }
//class Map: method getInit() is not recognised???
public class Map extends JPanel implements MouseListener
     private Image image;
     private World world;
private int x,y;     
     private JPanel p = new JPanel();
     private JFrame frame = new JFrame();
     private Applet $applet;
     public Map(String name,int xp,int yp, World w, Applet a)
          $applet=a;
          x=xp;
          y=yp;
          world = w;
          MediaTracker media = new MediaTracker(this);
     image = Toolkit.getDefaultToolkit().getImage(name);
     media.addImage(image, 0);     
          try
               { media.waitForID(0); }
     catch (Exception e) {}
     frame.getContentPane().add(this, BorderLayout.CENTER);
          frame.setSize(1100,750);
          frame.setLocation(0,0);
          frame.show();
          addMouseListener(this);
public void paint(Graphics g)
     if($applet.getInit() == true ) //////...cannot resolve symbol...symbol : method getInit ()
          g.drawImage(image, x, y, this);
          world.displayWorld(g);
public void mouseClicked(MouseEvent e)
     world.setStrength(10);
     repaint();

Answer 1

when I try this, i get a null pointer exception @if(main.getInit()==true)
public class Map extends JPanel implements MouseListener
private Main main; ////instead of the horrible $applet :)
public Map(String name,int xp,int yp, World w, Main m)
main=m;
public void paint(Graphics g)
if(main.getInit() == true ) //////...cannot resolve symbol...symbol : method getInit ()
g.drawImage(image, x, y, this);
world.displayWorld(g);
ps: new to java..., forgive me for asking dumb questions
