Subject Re: [RNG] Generating for nums
Date Fri, 04 Aug 2017 18:10:57 GMT
For example, I have a enum like:

public enum CardinalDirection (NORTH,SOUTH,EAST,WEST)

and I want to say

traveler.travel(nextRandomDirection());

where

public CardinalDirection nextRandomDirection() {
   return rng.next(CardinalDirection.class);
}
