Java Applet - Sharing Variables With Another Class

I have An Issue With My Java Applet. Im Trying To Share My Variables With Another Class, But Its Not Working.

Class 1

package com.Tobysmith10.game.main;
import java.applet.Applet;
import java.awt.Graphics;
public class Game extends Applet{
public void init(){
 setSize(850,480);
 public void paint(Graphics g){
 g.fillOval(x,y,20,20);
}
}

Class 2

package com.Tobysmith10.game.main;
import java.applet.Applet;
public class gameLoop extends Applet implements Runnable{
public int x, y;
public void run(){
while(true){
x = 100;
y = 100; 
}
}
}

So im sharing the x and y variables with the Class 1 , but I get yellow lines under it and when i run the program, it crashes, how do I get class 1 to recognize the variables from class 2 ?
