I have seen different approaches to define a static array in Java. Either: String[] suit = new String[] { "spades", "hearts", "diamonds", "clubs" }; ...or only String[] suit = { "spades", "hearts", "diamonds", "clubs" }; or as a List List suit = Arrays.asList( "spades", "hearts", "diamonds", "clubs" ); Is there a difference (except for the List definition of course)? What is the better way (performance wise)? If you are creating an array then there is no difference, however, the following is neater: String[] suit = { "spades", "hearts", "diamonds", "clubs" }; But, if you want to pass an array

When I need to shuffle a deck of poker cards in Java/Android, I use Collections.shuffle(List<?> list) , of course. I've ever been doing this and the results seemed acceptable. But they aren't. As outlined in this paper , there are 52! possible unique shuffles of a 52 card poker deck. That amounts to about 2^226. But Collections.shuffle(List<?> list) uses new Random() by default which uses a 48-bit seed and can therefore only create 2^48 unique shuffles - which is only 3.49*10^(-52) percent of all possible shuffles! So how do I shuffle cards the right way? I've started using SecureRandom , but

These are my two structs: typedef struct _card { int suit; int value; } card; typedef struct _deck { int num_cards; card *cards; } deck; This is my make a card function: card *make_card(int suit, int value) { card *newCard = malloc(sizeof(card)); newCard->suit = suit; newCard->value = value; return newCard; } Now is where I am a bit stuck. I have to make a deck of cards. I know how to assign each value to the card, but I am stumped on how to allocate it in memory. I know it has to do with an array of cards in the deck struct but i cant figure out how. deck *make_standard_deck() { for (int i =

I have an array of integers called cards[52]. Each element contains an integer that represents a card (cards[0] = 5 would represent the 6 of clubs for example). This is how I shuffled the array. It works, but I am getting repeats. private void shuffleCards() { for (int i = 0; i < cards.Length; i++) { int randIndex = r.Next(0, 52); int origCard = cards[i]; cards[i] = cards[randIndex]; cards[randIndex] = origCard; } } r is the Random variable I initialized in the beginning of the program. When testing the program, I noticed I would get the same card 2 or 3 times. Obviously I cannot get repeats,

I'm just setting out in android development. I want to make a kind of card based game. I'm just looking for suggestions really on how I might start it. I know I have to make the menu layout and view, then use an Intent from that to get to the main game view. My sticking points are: There's going to be a deck of cards. It's going to be a set number so I was thinking I could just have each card defined as a button in the layout. I don't know if that is the right way to do it though. Storage of card details. I'm thinking of using an xml file to store these. You could try to check out this project
