Class Card (lines 153 170) contains two String instance variables face and suit that are used to store references to the face name and suit name for a specific Card. The constructor for the class receives two Strings that it uses to initialize face and suit. Method toStringis provided to create a Stringconsisting of the faceof the card, the string “of”and the suitof the card. Class DeckOfCards(lines 11 150) consists of an array deckof 52 Cards, an integer currentCard representing the most recently dealt card in the deck array ( 1 if no cards have been dealt yet) and the GUI components used to manipulate the deck of cards. The constructor method of the application instantiates the deck array (line 29) and uses the for structure at lines 33 35 to fill the deckarray with Cards. Note that each Cardis instantiated and initialized with two Strings one from the faces array (Strings “Ace” through “King”) and one from the suitsarray (”Hearts”, “Diamonds”, “Clubs” and “Spades”). The calculation count%13 always results in a value from 0 to 12 (the Copyright 1992 2002 by Deitel & Associates, Inc. All Rights Reserved. 7/7/01
