Java Letter Distance?
===

Is there a way to find the distance of letters in Java?

What I mean is for example:

    A -> C = 3 (as A, B, C)
    B -> G = 6 (as B, C, D, E, F, G)
    R -> Z = 9 (as R, S, T, U, V, W, X, Y, Z)

(I am looking for distance that is inclusive of the first letter) 

Thanks!
