Method Detail

main

public static void main(java.lang.String[] args)

The main entry point. Also provides the main menu for the game and determines the flow of the program.

Parameters:

args - Command line arguments.

deal

private static void deal()

Creates a new deck, shuffles it, and deals out cards equally to all players.

play

private static void play()

Runs the game turn by turn until a player wins. The turn loop first checks if a player has won the game, if not, it checks to see what players are still in the game. A player is removed from the game if they run out of cards. A player wins the game if they are the only player left. Otherwise, a single card is drawn from each player's hand. Whoever's card has the highest value, that player wins all of the cards that were drawn. They are added to their hand. The turn then ends. If however, two or more players draw a card of the same value, there is a war. In the case of a war, the players involved draw three more cards and then one more card to compare against the other players. The player in the war with the highest value of their final card drawn wins all of the cards involved.

                           java.util.ArrayList<Card> currentCards)
