Another Java Question Niggers

I have a method that manipulates a string and returns said manipulated string. The problem is, that I don't know how to input a string into this method from "str = keyboard.nextLine();" (str being the string i need to put into the method) any kind anon have an idea. I have also tried a google search, no luck. Although I'm probably searching with the wrong keyword
