### Question:
EclipseCollectionsDeckOfCardsAsList { public Bag<Rank> countsByRank() { return null; } EclipseCollectionsDeckOfCardsAsList(); 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); ImmutableList<Card> diamonds(); ImmutableList<Card> hearts(); ImmutableList<Card> spades(); ImmutableList<Card> clubs(); Bag<Suit> countsBySuit(); Bag<Rank> countsByRank(); ImmutableList<Card> getCards(); ImmutableListMultimap<Suit, Card> getCardsBySuit();  }### Answer:
@Test public void countsByRank() { Assert.assertEquals( this.jdkDeck.countsByRank().get(Rank.TEN).intValue(), this.ecDeck.countsByRank().occurrencesOf(Rank.SEVEN)); }
