Question

*in Java

1.Create a card class with two attributes, suit and rank.

2.In the card class, create several methods:

a. createDeck – input what type of deck (bridge or pinochle) is to be created and output an array of either 52 or 48 cards.

b.shuffleDeck – input an unshuffled deck array and return a shuffled one.

+ Create a swap method to help shuffle the deck

c. countBridgePoints – inputs a 13-card bridge ‘hand’-array and returns the number of high-card points

d. writeHandOutput – input a bridge-hand and prints it out on the monitor

e. writeDeckOuput – inputs a deck of bridge cards and prints it out on the monitor

3. main method should:

a. Ask the user what kind of deck he/she wants to create (pinochle or bridge). For this project, have the user input ‘bridge’.

b. Create the user-asked-for deck

c. Print out the unshuffled deck

d. Shuffle the deck

e. Create 4 Bridge hands of 13 cards each, call them North, South, East and West.

+ Deal every fourth card to each of the hands

f. Calculate the high-card-points in each hand

g. Print out each hand and the number of high-card-points associated with each hand

h. Sort the hands from highest to lowest number of points – use Insertion Sort we did before

i. Print out each hands points from highest to lowest.

Answer 1

I'm not sure whether my code is correct or wrong, but I hope it works. Actually I don't know the play of pinochle or the Bridge Game, so I wrote the code for the HighLow Game with a slight modifications in the method names! Hope it works with you.

Source Code:

public class Card {
   
   public final static int SPADES = 0;   // Codes for the 4 suits, plus Joker.
   public final static int HEARTS = 1;
   public final static int DIAMONDS = 2;
   public final static int CLUBS = 3;
   public final static int JOKER = 4;
   
   public final static int ACE = 1;      // Codes for the non-numeric cards.
   public final static int JACK = 11;    //   Cards 2 through 10 have their 
   public final static int QUEEN = 12;   //   numerical values for their codes.
   public final static int KING = 13;
   private final int suit; 
   private final int value;
   public Card() {
      suit = JOKER;
      value = 1;
   }
   public Card(int theValue, int theSuit) {
      if (theSuit != SPADES && theSuit != HEARTS && theSuit != DIAMONDS && 
            theSuit != CLUBS && theSuit != JOKER)
         throw new IllegalArgumentException("Illegal playing card suit");
      if (theSuit != JOKER && (theValue < 1 || theValue > 13))
         throw new IllegalArgumentException("Illegal playing card value");
      value = theValue;
      suit = theSuit;
   }
   public int getSuit() {
      return suit;
   }
   public int getValue() {
      return value;
   }
   public String getSuitAsString() {
      switch ( suit ) {
      case SPADES:   return "Spades";
      case HEARTS:   return "Hearts";
      case DIAMONDS: return "Diamonds";
      case CLUBS:    return "Clubs";
      default:       return "Joker";
      }
   }
   public String getValueAsString() {
      if (suit == JOKER)
         return "" + value;
      else {
         switch ( value ) {
         case 1:   return "Ace";
         case 2:   return "2";
         case 3:   return "3";
         case 4:   return "4";
         case 5:   return "5";
         case 6:   return "6";
         case 7:   return "7";
         case 8:   return "8";
         case 9:   return "9";
         case 10:  return "10";
         case 11:  return "Jack";
         case 12:  return "Queen";
         default:  return "King";
         }
      }
   }
   public String toString() {
      if (suit == JOKER) {
         if (value == 1)
            return "Joker";
         else
            return "Joker #" + value;
      }
      else
         return getValueAsString() + " of " + getSuitAsString();
   }
   

} // end class Card

This is the required card class.

Now the program for the HighLow game is given below:

Source Code:

public class HighLow {


   public static void main(String[] args) {

      System.out.println("You have to predict whether the next card will be");
      System.out.println("higher or lower.  Your score in the game is the");
      System.out.println("number of correct predictions you make before");
      System.out.println("you guess wrong.");
      System.out.println();
      
      int gamesPlayed = 0;     // Number of games user has played.
      int sumOfScores = 0;     // The sum of all the scores from 
                               //      all the games played.
      double averageScore;     // Average score, computed by dividing
                               //      sumOfScores by gamesPlayed.
      boolean playAgain;       // Record user's response when user is 
                               //   asked whether he wants to play 
                               //   another game.
      
      do {
         int scoreThisGame;        // Score for one game.
         scoreThisGame = play();   // Play the game and get the score.
         sumOfScores += scoreThisGame;
         gamesPlayed++;
         System.out.print("Play again? ");
         playAgain = TextIO.getlnBoolean();
      } while (playAgain);
      
      averageScore = ((double)sumOfScores) / gamesPlayed;
      
      System.out.println();
      System.out.println("You played " + gamesPlayed + " games.");

                       //    to predict whether this is higher or lower

      int correctGuesses ;  // The number of correct predictions the

Hope this helps you well!!
