Jgraspwrite A Class Named Card Which Can Be Used To Represent A Card

Write a class named Card, which can be used to represent a card from a deck of cards. The class should be able to store a card's suit and face value. A card's suit can be one of the following: Hearts, Diamonds, Clubs, Spades. A card's face value can be Ace, King, Queen, Jack, or a value in the range 2 through 10. Next, write a Deck class. This class's constructor should create a list of 52 Card objects, each representing a valid card in the deck. The class should have a shuffle method that randomly shuffles the Card objects in the list. It should also have a deal method that deals a card from the deck by removing the Card object at the beginning of the list and returning a reference to the object. Next, write a CardPlayer class. This class should keep a list of Card objects that have been dealt to it, representing a hand of cards. It should have an add method that accepts a reference to a Card object and adds it to its list. It should also have a showCards method that displays all the Card objects in its list. Finally, demonstrate these classes in an application that creates a Deck object, shuffles the cards, deals five cards to a CardPlayer object, and then displays those five cards. Include appropriate comments in the code for clarity.

Implementation of Card Deck and Player Classes in Java

This paper presents a comprehensive implementation of a card deck and player system in Java, designed to simulate the dealing of cards from a standard deck of 52 playing cards. The core classes include Card, Deck, and CardPlayer. Each class is described in detail, highlighting its attributes and methods, followed by a demonstration program that exemplifies their combined use.

1. The Card Class

The Card class encapsulates the fundamental properties of a playing card, namely suit and face value. The class defines constants for suits and face values and provides constructors, getter methods, and a method to display the card's information clearly.

2. The Deck Class

The Deck class creates a collection of 52 unique Card objects representing all suits and face values in a standard deck. It includes methods for shuffling, which randomizes the order of the cards, and dealing, which removes and returns the top card from the deck. The class utilizes Java's Collections.shuffle() method to perform shuffling.

3. The CardPlayer Class

The CardPlayer class maintains a list of cards dealt to it, representing a player's hand. It provides methods to add new cards and to display all cards currently held by the player, revealing their suit and face value.

4. Demonstration Program

In the main application, an instance of Deck is created, shuffled, and then used to deal five cards to an instance of CardPlayer. The player's hand is then displayed, showing the dealt cards, demonstrating the effective working of the classes together.

5. Implementation Code

Card.java

// Card class to represent individual playing cards
public class Card {
// Enum for suits
public enum Suit {
HEARTS, DIAMONDS, CLUBS, SPADES
}
// Attributes for suit and face value
private Suit suit;
private String faceValue;
// Constructor
public Card(Suit suit, String faceValue) {
this.suit = suit;
this.faceValue = faceValue;
}
// Getter for suit
public Suit getSuit() {
return suit;
}
// Getter for face value
public String getFaceValue() {
return faceValue;
}
// Method to display card info
public String displayCard() {
return faceValue + " of " + suit.toString();
}
}

Deck.java

// Deck class to hold and manage a collection of 52 cards
import java.util.ArrayList;
import java.util.Collections;
public class Deck {
private ArrayList<Card> cards;
// Constructor
public Deck() {
cards = new ArrayList<>();
String[] faceValues = {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King"};
for (Card.Suit suit : Card.Suit.values()) {
for (String face : faceValues) {
cards.add(new Card(suit, face));
}
}
}
// Method to shuffle the deck
public void shuffle() {
Collections.shuffle(cards);
}
// Method to deal a card
public Card deal() {
if (!cards.isEmpty()) {
return cards.remove(0);
} else {
return null; // No more cards
}
}
}

CardPlayer.java

// CardPlayer class to represent a player holding a hand of cards
import java.util.ArrayList;
public class CardPlayer {
private ArrayList<Card> hand;
// Constructor
public CardPlayer() {
hand = new ArrayList<>();
}
// Method to add a card to the hand
public void add(Card card) {
hand.add(card);
}
// Method to display cards in hand
public void showCards() {
System.out.println("Player's Hand:");
for (Card card : hand) {
System.out.println(card.displayCard());
}
}
}

Main Application: CardGameDemo.java

// Main class to demonstrate card dealing
public class CardGameDemo {
public static void main(String[] args) {
// Create and shuffle deck
Deck deck = new Deck();
deck.shuffle();
// Create a player
CardPlayer player = new CardPlayer();
// Deal five cards to the player
for (int i = 0; i 
Card dealtCard = deck.deal();
if (dealtCard != null) {
player.add(dealtCard);
}
}
// Show player's hand
player.showCards();
}
}

Conclusion

This implementation demonstrates a complete object-oriented approach to simulating a card game system in Java, including card representation, deck management, shuffling, dealing, and holding a player's hand. Proper encapsulation and modularity ensure that each component performs its function efficiently and clearly. Such a structure can be extended to support more complex card games by adding game-specific logic.
