1. Card 크레스 Card String suit String face intrank Card(String, String, int) Card() intcompareTo(Card) StringtoString()

2. Deck 크레스 Deck ArrayList<Card> cards Deck() Card deal() 52 Card 객체들: Hearts, Diamonds, Spades, Clubs Ace, Deuce, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King

3. publicDeck() { //constructor cards = newArrayList<Card>(); String[] suit = {"Clubs", "Spades", "Hearts", "Diamonds"}; String[] face = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"}; for(intx = 0; x < 52; x++) { Card c = new Card(); c.setSuit(suit[x / 13]); c.setFace(face[x % 13]); c.setRank((x % 13) + 1); cards.add(c); } Collections.shuffle(cards); }

6. Hand Evaluation • 2 methods: • eval() • calcHandValue(int, int, int, int)

7. eval() • Multiple cards of same rank: • Four of a kind, full house, three of a kind, 2pair, pair • 5 cards in order of rank • Str8 • 5 cards of same suit • Flush

8. Example: flush

10. sameSuit[0] sameSuit[1] sameSuit[2] sameSuit[3] = 0 = 0 = 0 = 1

12. Write Hand class

13. Make JUnitTest

14. Download flush_test.zip

15. calcHandValue(int,int,int,int) • Instance variable handValuecalculation, representing the strength of the hand

16. inthandValue • Six 4bit ‘words’ : 0000 0000 0000 0000 0000 0000 Type Card1 Card2 Card3 Card4 Card5

17. inthandValue • First ‘word’ - Type 1000 isStr8Flush 0111 is4 0110 isFull 0101 isFlush 0100 isStr8 0011 is3 0010 is2Pair 0001 isPair

18. Example: isFlush Player 1: Player 2:

19. Example: isFlush Player 1: inthandValue: 0000 0000 0000 0000 0000

20. Example: isFlush Player 1: inthandValue: 1101 1010 0111 0100 0011 Bit Shift Operation: 13<<16 10<<12 7<<8 4<<4 3

21. inthandValue • First ‘word’ - Type 1000 isStr8Flush 0111 is4 0110 isFull 0101 isFlush 0100 isStr8 0011 is3 0010 is2Pair 0001 isPair

22. Example: isFlush isFlush Player 1: inthandValue: 0101 1101 1010 0111 0100 0011 5<<20 Bit Shift Operation: 13<<16 10<<12 7<<8 4<<4 3

23. Example: isFlush isFlush Player 1: inthandValue: 6,137,667

24. Example: isFlush isFlush Player 1: 6,137,667 inthandValue: isFlush Player 2: 6,137,666 inthandValue:

25. Example: isFlush 6,137,667 > 6,137,666 Player 1 wins!

26. Write calcHandValue() method Add to evalTest(): assertEquals(h.handValue, 6137667)
