Write a MAD calculation method just as we did in class EXCEPT the method should accept two twodimensional String arrays as arguments (one two-dimensional String array will contain the observed demand read from Demand. txt and the other two-dimensional String array will contain forecasted demand values). Both methods still should return a double. Note that this question should require a basic modification to the code we wrote in class MAD.

What's the rest of it? lol
