### Question:
EclipseCollectionsDeckOfCardsAsSortedSet { public ImmutableSortedSet<Card> diamonds() { return null; } EclipseCollectionsDeckOfCardsAsSortedSet(); MutableStack<Card> shuffle(Random random); MutableSet<Card> deal(MutableStack<Card> stack, int count); ImmutableList<Set<Card>> shuffleAndDeal(Random random, int hands, int cardsPerHand); ImmutableList<Set<Card>> dealHands(
            MutableStack<Card> shuffled,
            int hands,
            int cardsPerHand); ImmutableSortedSet<Card> diamonds(); ImmutableSortedSet<Card> hearts(); ImmutableSortedSet<Card> spades(); ImmutableSortedSet<Card> clubs(); Bag<Suit> countsBySuit(); Bag<Rank> countsByRank(); ImmutableSortedSet<Card> getCards(); ImmutableSortedSetMultimap<Suit, Card> getCardsBySuit();  }### Answer:
@Test public void diamonds() { Assert.assertEquals(this.ecDeck.diamonds(), this.jdkDeck.diamonds()); }
