Sorry if there's something obvious I missed here. For example, let's say I'm making a card game and want to make store a bunch of constants of type Card in a class Cards. After all, there are only a limited number of kinds of playing cards so it makes sense to store them all as reference values. This might be useful if I had a method Deck.hasCard(Card c), for example. If I want to see if a Deck has a five of spades, for example, I shouldn't have to create a new Card() just to do that. However, I don't see a way to do that without either manually specifying every kind of card possible, (the two ways I know how to do this are to either use an enum, or maybe make a regular class then include them as part of a data structure like ArrayList<>) or including a constructor to iterate over the suits and values which doesn't make sense for what is basically an enum. Please let me know if I'm wrong about or missing something.
