How to operate the poker game by Java?

Question

I’ve learned Java for 1 month. This time, I’d like to create a poker game. There are two questions about my program. I hope somebody can help me to fix it.

Answer 1

For your first question, you could map a card name to its value:

Map values = new HashMap();
values.put("A", 11);
values.put("2", 2);
// ...
values.put("King", 10);

// lookup a value:
int kingValue = values.get("King");

For the second, I'd rely on java shuffle function. Create a list of all cards

ArrayList deck = someMagicMethodToPopulateTheList();

and then simply shuffle the deck

Collections.shuffle(deck);

Now you can iterate through the deck and you will see the cards in a random order:

for (Card card:deck) {
  System.out.println(card);
}

Note: the Card class does not extist (yet). I simply invented the name to keep it simple)
