Question

Given these three classes: Card, DeckOfCards, and DeckOfCardsTest. Extend the DeckofCards class to implement a BlackJack class, which implements a BlackJack game. Please do not use any java applet on the coding.

Hint: Use a test class to test above classes.

Pulic class Card
{
   private final String face; // face of card ("Ace", "Deuce", ...)
   private final String suit; // suit of card ("Hearts", "Diamonds", ...)

   // two-argument constructor initializes card's face and suit
   public Card(String cardFace, String cardSuit)
   {
       this.face = cardFace; // initialize face of card
       this.suit = cardSuit; // initialize suit of card
   }

   // return String representation of Card
   public String toString()
   {
       return face + " of " + suit;
   }
} // end class Card
