static Z g(String s){...} returns the appropriate enum constant which has the planet's distance from Mercury.

static long d(String...s){...} solves the challenge. Input requires names of planets to have the first letter capitalized and the rest ofmatch the name in lower caseenum's constants' names exactly. I love how java provides a string to enum conversion method for me <3

Usage:

Z.d("Mercury","Pluto") returns 5848470000

Z.d("Pluto","Mercury") returns -5848470000

Z.d("Uranus","Neptune") returns 1627450000

Z.d("Mars","Pluto") returns 5678440000
