Poker

[umairmehmood]

Hello,
Is there any Poker game written in Java that has source code along with for analysis.

[Riven]

google -> 2nd hit -> sourcecode

For your amusement: My Poker4k sourcecode (screens: click click click click, JAR, JNLP)

Not bad though...!!
but still the example is quiet simple.
I was looking for a combination of a complex codes and a little bit of Shuffling + Distribution Algorithm to go along with.

Help required.

This should probably bein clueless newbies but....

Quick deck shuffling algorithym:

1   2   3   4   5   6   7   8

(1)Allocate an integer array with length 52. (2) Loop from 0 to 51 adn set deck[i] = i (3) Loop for some number of times (say 50) and do the following (swap pairs of cards):    x = random from 0  to 51    y=  random from 0 to 51    temp = deck[x]    deck[x]=deck[y]    deck[y]=temp

[Riven]

Well, it could be much more efficient:

1   2   3   4   5   6   7   8

Random r = new Random(); for(int i=0; i<52; i++) {     int from = i;     int to = (i + 1) + r.nextInt(52 - i - 1);     swap(from, to); }

It handles the remaining cards as a pool to take cards from.

If you are only drawing cards, not peeking ahead or inserting any, then an easy option is to implement the deck as a list of cards and yield a random one on draw.  E.g.:

1   2   3   4   5   6   7   8

class Deck {   private List<Card> theDeck;     public Card draw() {     if (theDeck.size()==0) throw NoSuchElementException();     else return theDeck.remove(Math.random() * theDeck.size());   } }

From the client's point of view (that is, according to the object's interface), the deck is shuffled, and in an OO system, that's all that matters

Well, it could be much more efficient:

heh by quick I meant "im dashing this off quick."

Im sure there are more efficient means. Im not sure its worth a lot of effort to find them

1	Collections.shuffle(deck);

try reading from page 17 for the whole shabang.
