I would provide some kind of predicate or IComparer to allow for this (sorry this is C# language - I'm not sure what the Java equivalent is). By having the DeckOfCards return a sequence of numbers e.g. Now to shuffle the initial list, another empty ArrayList is created. My mind went more or less blank at the session, but I just thought about it again a day or so ago, then came up with this as a solution.
