Overview
Blackjack is the most popular casino gambling game in the world. (Note: the rules of the game favor the casino. The Casino is guaranteed to win in the long run.) Here's how it works:
1. Both you and the House (the Casino) are dealt two cards: one is face up and the other face down. So you can see only one of the House's cards and it can see only one of yours. But both you and the House can discreetly peek at your face down cards.
2. Each card has a score as follows:
● An Ace has a score of 1. (This differs from real Blackjack where the Ace can have a score of either 1 or 11 at the player's discretion. The simplified version for this lab is easier to program.)
● A Jack, Queen or King has a score of 10.
● All other cards have a score equal to their rank. (For example, the 4 of Hearts or the 4 of any suit have a rank of 4 and a score of 4.)
3. The House will obtain additional cards until its score is 17 or more.
4. You are asked if you want another card. If you answer yes, you get another face down card and you will be asked again. This continues until you say "no". This ends the game.
5. All cards are now turned face-up and the scores of you and the House are calculated.
● You lose if your score is more than 21 (no matter what the House's score is).
● You lose if your score is the same as the House's.
● You win if:
o You don't go over 21 and the House does go over 21 o Both your scores are 21 or under and your score is more than the House's.
The Card Class
The Card class will consist of instance variables, a constructor and the methods. The template contains javadocs for all the methods. You should generate the html representation of the class to have an easier representation of the class's API (Application Programmer Interface). Many of the methods are only stubs and you have to modify them so that they implement the API.
The template will compile and it has a main method that will run but it produces the wrong output.
Source Code
Card.java, CardPile.java, BlackJackGame.java, UserInterface.java and
SimpleUI.java classes are provided with the lab. More details about these classes are in the instructions below.
Step 1: Create a Netbeans Project and Card class
1. Create a Netbeans project called Blackjack.
2. Create a Java file (class library type) called Card with package coe318.lab5. (All java files in this lab should have that package declaration.)
3. Determine your instance variables and implement the constructor.
4. Implement the other methods.
5. Important: Do not continue to the next class until this class works!
Step 2: Implement the remaining classes
You should get the CardPile class to work before proceeding. (It has its own main method.)
You next have to create the BlackjackGame and SimpleUI classes starting with the templates provided. You also have to create an interface (UserInterface) copying the code given in D2L. To create an interface in Netbeans, create a new file and have an interface (not a class) created. We have not covered interfaces yet in lectures. However, the only thing you need to know for now is that this file is essential and must not be modified.
Note: All three of these templates have to be loaded in order for them to compile without error.
Additional Notes
1. The Card class compareTo(Card c) method should return a negative, zero or positive value depending on whether “this” is less than, equal to or greater than the other card. For 2 cards of unequal rank, the one with the higher rank is “bigger”. If the ranks are the same, the suit is considered; the suit orders (from lowest to highest) are Clubs, Diamonds, Hearts, Spades.
2. The Card equals(Card c) method should only return true if the cards have the same suit and
rank.
Sample Gaming Sessions
The following are 2 sample sessions. In one the House wins, in the other you win.
Note: The format of the output is not defined. Within SimpleUI you can format the output of display(), hitMe() and gameOver()any way you want.
