Java SE implemention for Texas Hold'em Poker

It's fully functional core engine implentation of Texas Hold'em Poker.

Check out the following example

	GameTexasHoldem game = new GameTexasHoldem();
	IPlayer homer = new Player();
	IPlayer flanders = new Player();
	IDeck deck = new Deck();
	// The Deck and Player used in the GameTexasHoldem are interfaces..
	// The newGame signature: public void newGame(IDeck deck, IPlayer player1, IPlayer... _players).
	// At least one player is mandatory to start the game, but you can add as many players as you want (Java Varargs).
	game.newGame(deck, homer, flanders);
	game.deal();
	game.callFlop();
	game.betRiver();
	game.betTurn();
	List<IPlayer> winnerList = game.getWinner();
	
        // Getting the result
	if(winnerList.size() > 1){
		// DRAW GAME
	} else if(winnerList.contains(homer)) {
		// HOMER WINNER
		// WINNER HAND: homer.getRankingEnum();
	} else if(winnerList.contains(flanders)) {
		// FLANDERS WINNER
		// WINNER HAND: flanders.getRankingEnum();
	}
	
	// The table cards
	game.getTableCards(); 
	
	// To get the player actual ranking
	homer.getRankingEnum();
	flanders.getRankingEnum();
	// IPlayer.getRankingEnum() can be changed in deal, call flop, bet river and bet turn.

The IPlayer.getRankingEnum() method returns RankingEnum which contains the actual ranking of the player.

	public enum RankingEnum { {
		ROYAL_FLUSH, 
		STRAIGHT_FLUSH, 
		FOUR_OF_A_KIND, 
		FULL_HOUSE, 
		FLUSH, 
		STRAIGHT, 
		THREE_OF_A_KIND, 
		TWO_PAIR, 
		ONE_PAIR, 
		HIGH_CARD
	}
