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!

You know the best thing about you trying to act like you know shit is that your code didn't event work properly, i even copied and pasted it just to make sure i didn't type it wrong:
