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?
