global instance variable problem

Code:

---

import java.net.*;
import java.io.*;

public class GuessNumberHandlerServer {
}


class GuessNumberHandler extends Thread {
}

---

MagicNumber magNumb = new MagicNumber();

how can i declare that outside the functions?

so i can use mnumb.whatever (same instance of the magicnumber class) in both the 'public class' and the 'class' function?

what im actually trying to do is create magNumb in this: public class GuessNumberHandlerServer

and i want to use magNumb in the 'GuessNumberHandler extends Thread' please may someone tell me how?

you seem to have a wrong idea about what a "Class" is, you should read more about Object Oriented Programming...After that, I'll be very glad to answer any questions
