JAVA "to the power of"

Sup /prog/?

I know this is a retarded question, but I need some help with a method I need to write. The method parameters are a double and an int (a and b, respectively)

I need to write a for loop in the method that raises a (the double) to the power of b (the int)

How the fuck do I do this?? Normally this wouldn't be a problem, but I'm burnt out from finals

This isn't really programming, I know how to do loops and shit, this is just math that I am having trouble with
