Blackjack 🃏

I created Blackjack in Java using JOptionPane as my GUI and an ArrayList of card objects to simulate a deck of cards. The program follows the traditional rules of Blackjack where the dealer must draw to 16 and stand on all 17s.

Instructions

$ java card and the game should appear as a JOptionPane pop up and you will be able to play. Have fun!

Breakdown

import java.util.ArrayList;
import java.util.Random;
import javax.swing.JOptionPane;

public class Card {
  
  // constructors for the card object called by buildDeck
  public Card()
  public Card(String num, String suit)
  
  // checks if one card is exactly the same as another card (suit and value)
  @Override
  public boolean equals(Object newCard)
  
  // creates a unique deck of cards and shuffles them using a Fisher-Yates shuffling algorithm where a loop iterates 
  // through every index in the ArrayList of the deck, swapping the current card with another random card.
  public static void buildDeck(ArrayList<Card> deck)
  
  // deals 4 cards, 2 to player, 2 to dealer
  public static void initialDeal(ArrayList<Card> deck, ArrayList<Card> playerHand, ArrayList<Card> dealerHand)
  
  // helper methods
  public static void dealOne(ArrayList<Card> deck, ArrayList<Card> hand)
  public static int getHandValue(ArrayList<Card> hand)
  public static boolean checkBust(ArrayList<Card> hand)
  public static boolean dealerTurn(ArrayList<Card> deck, ArrayList<Card> hand)
  public static int whoWins(ArrayList<Card> playerHand, ArrayList<Card> dealerHand)
  public static String displayCard(ArrayList<Card> hand)
  public static String displayHand(ArrayList<Card> hand)
  public static void clearHands(ArrayList<Card> playerHand, ArrayList<Card> dealerHand)
  
  // using JOptionPane, display game with hit and stay options
  public static void main(String[] args)
}
