题目要求

完成CardDeck类，以便您可以通过比较您和计算机抽取的卡片与计算机进行PK。
游戏设计要求：

• In this game, the value of a card is set from small to big: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen and King.
• And the suit of a card is set from small to big: Clubs, Diamonds, Hearts and Spades

解答示范

Card类

这个类定义扑克牌的基本属性：花色和数字，并分别设置一个返回函数

class Card {private int suit;private int value;public Card (int s, int v) {suit = s;value = v;}public int getSuit() {return suit;}public int getValue() {return value;}
}

CardDeck类

这个类负责初始化54张扑克牌，洗牌和随机抽牌，最后再与电脑抽取的扑克牌进行比较，将抽出的牌以单词的形式返回出来，并告知孰输孰赢

class CardDeck {// fieldsprivate Card[] cards;//constructorspublic CardDeck(){cards = new Card[52];int k = 0;for(int i = 0; i < 13; ++i)for(int j = 1; j <= 4; ++j)cards[k++] = new Card(j, i);}//methodsvoid shuffle() {for(int i = 0; i < 52; ++i) {int replacement = (int)(Math.random() * 52);swap(replacement, i);}}public Card drawRand() {int num = (int)(Math.random() * 52);return cards[num];}public Card drawManually(int i) {return cards[i];}private void swap(int i, int j) {Card tmp = cards[i];cards[i] = cards[j];cards[j] = tmp;}public String value_to_str(int value) {String str1 = null;switch(value){  case 0:  str1="Ace";  break;  case 1:  str1="2";  break;  case 2:  str1="3";  break;  case 3:  str1="4";  break;  case 4:  str1="5";  break;  case 5:  str1="6";  break;  case 6:  str1="7";  break;  case 7:  str1="8";  break;  case 8:  str1="9";  break;  case 9:  str1="10";  break;  case 10:  str1="Jack";  break;  case 11:  str1="Queen";  break;  case 12:  str1="King";  break;  }  return str1;}public String suit_to_str(int suit) {String str2 = null;switch(suit){  case 1:  str2="Clubs";  break;  case 2:  str2="Diamonds";  break;  case 3:  str2="Hearts";  break;  case 4:  str2="Spades";  break;  }  return str2;}int cmp_value(int Random_value, int Manually_value) {if (Random_value < Manually_value)return 1;else if (Random_value > Manually_value)return -1;elsereturn 0;}int cmp_suit(int Random_suit, int Manually_suit) {if (Random_suit < Manually_suit)return 1;else if (Random_suit > Manually_suit)return -1;elsereturn 0;}
}
