A new deck of cards is used for each game. */ public class Blackjack { public static void main(String[] args) { int money; // Amount of money the user has. int bet; // Amount user bets on a game. boolean userWins; // Did the user win the game? TextIO.putln("Welcome to the game of blackjack."); TextIO.putln(); money = 100; // User starts with $100. while (true) { TextIO.putln("You have " + money + " dollars."); do { TextIO.putln("How many dollars do you want to bet? (Enter 0 to end.)"); TextIO.put("? "); bet = TextIO.getlnInt(); if (bet < 0 || bet > money) TextIO.putln("Your answer must be between 0 and " + money + '.'); } while (bet < 0 || bet > money); if (bet == 0) break; userWins = playBlackjack(); if (userWins) money = money + bet; else money = money - bet; TextIO.putln(); if (money == 0) { TextIO.putln("Looks like you've are out of money!"); break; } } TextIO.putln(); TextIO.putln("You leave with $" + money + '.'); } // end main() static boolean playBlackjack() { // Let the user play one game of Blackjack. // Return true if the user wins, false if the user loses. Deck deck; // A deck of cards. A new deck for each game. BlackjackHand dealerHand; // The dealer's hand. BlackjackHand userHand; // The user's hand. deck = new Deck(); dealerHand = new BlackjackHand(); userHand = new BlackjackHand(); /* Shuffle the deck, then deal two cards to each player. */ deck.shuffle(); dealerHand.addCard( deck.dealCard() ); dealerHand.addCard( deck.dealCard() ); userHand.addCard( deck.dealCard() ); userHand.addCard( deck.dealCard() ); TextIO.putln(); TextIO.putln(); /* Check if one of the players has Blackjack (two cards totaling to 21). The player with Blackjack wins the game. Dealer wins ties. */ if (dealerHand.getBlackjackValue() == 21) { TextIO.putln("Dealer has the " + dealerHand.getCard(0) + " and the " + dealerHand.getCard(1) + "."); TextIO.putln("User has the " + userHand.getCard(0) + " and the " + userHand.getCard(1) + "."); TextIO.putln(); TextIO.putln("Dealer has Blackjack.

You win."); return true; } /* If neither player has Blackjack, play the game. First the user gets a chance to draw cards (i.e., to "Hit"). The while loop ends when the user chooses to "Stand". If the user goes over 21, the user loses immediately. */ while (true) { /* Display user's cards, and let user decide to Hit or Stand. */ TextIO.putln(); TextIO.putln(); TextIO.putln("Your cards are:"); for ( int i = 0; i
