          John Stegeman
          What do you mean? Do you mean you want to return two arrays (which is what I guess from reading that messy code)? Have you looked at two-dimensional arrays or creating a Java class with two array member variables and returning an instance of that class?
          java.lang.NullPointerException

          Is where your problem is one of your problems is, by the way
