NEED URGENT HELP

sup /prog/

Ive asked this everywer already but peopl seem too lame to make even a simple program like so i hope the mighty anon programers of 4chan are more skilled

what im trying to do is to Write a method taking two parameters x and n that computes the nth power of x without using ^ or declaring a new variable inside the method or using Math lib.
and it has to be coded in JAVA (i know it sux but dont ask why i use dat shit)
hep plox!

i know it can be done without recursion. Thank you for your concern in my future affairs with google. It is nice to know that people here are helpful enough to provide suggestions and go over this ordeal with me. I am an aspiring programmer i know this to be true and i don't understand how someone who has worked long and hard on such successful software as SmartFit (TM) can't understand a simple statement as such...
