Instance Variables with Applet Reflection

Hey guys, so I have a problem with hooking using reflection, the software I have was built so it can get methods from the applet. However I do not know how to grab instance variables.

This is the Class that Loads the applet and puts the main class into an interface called Client.

Code Java:

    Client hook;
 
   public void a() {
        try {
            ClassThing b1 = new ClassThing();
 
            byte abyte0[] = a("http://applet.com/appletlinkgoeshere", "Starting up");
            if (abyte0 == null)
                throw new Exception("Client download failed");
            b1.a = new ClientClassLoader(abyte0);
            Class class1 = b1.loadClass("sign.signlink");
            class1.getField("mainapp").set(null, this);
            Class class2 = b1.loadClass("client");
            reflectObject = class2.newInstance();
            _fldfor = (Applet) reflectObject;
            _fldfor.init();
            _fldfor.start();
            setClient((Client) _fldfor);
            /*java.lang.reflect.Field[] fields = class2.getFields();
            for (int i=0; i<fields.length;i++) {
            	System.out.println(fields[i]);
           }*/
        } catch (Exception exception) {
            String s = exception.getMessage();
            if (s == null)
                s = "null";
            a(s);
            exception.printStackTrace();
        }
    }
 
    public void setClient(Client c) {
        hook = c;
    }

This is the client interface with all the methods from within the applet

Code Java:

package com.bsbot.hooks;
 
import java.awt.*;
 
public interface Client extends RSApplet {
 
    public String getUsername();
 
    public String getPassword();
 
    public Component getGameComponentHook(int a);
 
    public Npc[] getNpcs();
 
    public int getBaseX();
 
    public int getBaseY();
 
    public Player getMyPlayer();
 
    public int getPlayerId();
 
    public int getTime();
 
 
    public int[] getMaxStats();
 
    public int[] getCurrentStats();
 
    public int[] getExperience();
 
    public boolean isLoggedIn();
 
    public Player[] getPlayers();
 
    public String getLoginMessage2();
 
    public boolean isMenuOpen();
 
    public String[] getMenuActionNames();
 
    public int getMenuActionRow();
 
    int getMenuOffsetX();
 
    int getMenuOffsetY();
 
    String[] getChatMessages();
 
    int getMinimapInt1();
 
    int getMinimapInt2();
 
    int getMinimapInt3();
 
    int getXCameraCurve();
 
    int getYCameraCurve();
 
    int getXCameraPos();
 
    int getYCameraPos();
 
    int getZCameraPos();
 
    int getPlane();
 
    public void setLoginIndex(int i);
 
    public int getLoginIndex();
 
    int getOpenTab();
 
    int[][][] getGroundIntArray();
 
    byte[][][] getGroundByteArray();
 
    GameInterface[][] getInterfaceCache();
 
 
    public String getSelectedItemName();
 
    public ItemDef getForId(int id);
 
    public ObjectDef getForIdObject(int id);
 
    int getMouseX();
 
    int getMouseY();
 
    public NodeList[][][] getGroundArray();
 
    public WorldController getWorldController();
 
}

So my question is how can I get and use an instance variable that already exists in the applet? For example, in the applet there is: public String eN;
How can I get the value of eN to use in my reflection program?
Help is VERY appreciated, because I've spent some time banging my head against my desk.
