homework

I know how to do it using simple recursion, but in order to complete this particular assignment I need to be able to accumulate on the stack and throw an exception that holds the answer in it.

So far I have:

public static int fibo(int index) {
    int sum = 0;
    try {
        fibo_aux(index, 1, 1);
    }
        catch (IntegerException me) {
    sum = me.getIntValue();
    }
    return sum;
}

fibo_aux is supposed to throw an IntegerException (which holds the value of the answer that is retireved via getIntValue) and accumulates the answer on the stack, but so far I can't figure it out. Can anyone help?

I think error handling is a good idea. :) When debugging it can get in the way - especially with nice user friendly messages.
