### Question:
JDKImperativeDeckOfCardsAsSortedSet { public List<Set<Card>> shuffleAndDeal(Random random, int hands, int cardsPerHand) { Deque<Card> shuffled = this.shuffle(random); return this.dealHands(shuffled, hands, cardsPerHand); } JDKImperativeDeckOfCardsAsSortedSet(); Deque<Card> shuffle(Random random); Set<Card> deal(Deque<Card> deque, int count); List<Set<Card>> shuffleAndDeal(Random random, int hands, int cardsPerHand); List<Set<Card>> dealHands(Deque<Card> shuffled, int hands, int cardsPerHand); SortedSet<Card> diamonds(); SortedSet<Card> hearts(); SortedSet<Card> spades(); SortedSet<Card> clubs(); Map<Suit, Long> countsBySuit(); Map<Rank, Long> countsByRank(); SortedSet<Card> getCards(); Map<Suit, SortedSet<Card>> getCardsBySuit();  }### Answer:
@Test public void shuffleAndDealHands() { List<Set<Card>> jdkHands = this.jdkDeck.shuffleAndDeal(new Random(1), 5, 5); Assert.assertEquals(5, jdkHands.size()); Assert.assertTrue(Iterate.allSatisfy(jdkHands, each -> each.size() == 5)); }
