Programming Blackjack In Java

Blackjack

Blackjack is a simple java program demonstrating file I/0 and using multiple classes in java. The program deals a blackjack hand, and checks the user's decisions (hit, stand, double or split) against correct strategy. The correct strategy is laid out in the text file 'bjin.txt' which should reside in the same directory as the program.

The program does not keep score in its present form, it simply checks the user's input (hit, stand, split or double) against the correct decision from bjin.txt. When the player chooses to split a pair, only one of the split hands is played. Type 'quit' at the command line to exit the program. Bjin.txt can be modified to change what the 'correct' decision is for a given hand.

The program consists of three java classes, Deck.java, Hand.java, and Blackjack.java.

Deck.java is a 52 card deck. The deal() function returns a string consisting of a numeric value, or J, Q, K, or A, representing a random card. When a card is dealt, deck marks that card as missing. deck will not reshuffle automatically, and will fail if more than 52 cards are dealt. The shuffle() function reshuffles the deck.

Hand.java represents a person's hand (either the player or the dealer). The hit() function takes a string consisting of a numeric value, or J, Q, K, or A, and adds it to it's array of cards. The other functions return different aspects of a hand.

Java Classes Used: Logic for Drawing Cards: 1) Random class of Java: Cards in the game are drawn at random. For that I used the random class of Java. 2) Binding cards with numbers: This random Class of Java works on numbers so we would need to bind the images of cards with numbers. Blackjack Blackjack is a simple java program demonstrating file I/0 and using multiple classes in java. The program deals a blackjack hand, and checks the user's decisions (hit, stand, double or split) against correct strategy. The correct strategy is laid out in the text file 'bjin.txt' which should reside in the same directory as the program.

Blackjack.java is where the main() loop is. The only real member variable it has is the array consisting of the correct choices under each situation.

This program can be compiled into a windows executable with gcj in cygwin, using the command:
gcj --main=Blackjack -mno-cygwin Blackjack.java Hand.java Deck.java -o blackjack.exe

This program can be compiled to java class files and run using the following commands:
javac Blackjack.java
javac Hand.java
Javac Deck.java
java Blackjack

One point of coding is the question of how to deal a card to the user or to the dealer.
