make a simple blackjack program using eclipse

Explanation / Answer

/* This program lets the user play Blackjack. The computer acts as the dealer. The user has a stake of $100, and makes a bet on each game. The user can leave at any time, or will be kicked out when he loses all the money. House rules: The dealer hits on a total of 16 or less and stands on a total of 17 or more. Dealer wins ties. 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.
