Thread: Enumeration

Hello.


I have this Card class that prints out some random cards that the user can choose and another classed called Deck that does all the heavier work, however the assignment says to do i "enum" or enumeration for all the enumerations in both classes and i feel lost because i am not sure if i am already doing it.

Both classes together is basically a deck of cards that you take some cards from and it will pick some random cards.

What do you guys think?

Main :

import java.util.*;
 
public class Card {
 
	static String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs" };
	static String[] rank = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King" };
 
	public static final int[] ourDeck = new int[52];
 
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
 
		Deck objectDeck = new Deck();
		objectDeck.stack(ourDeck);
		objectDeck.flush(ourDeck);
		System.out.print("Please write in the number of cards that you would like to get : ");
		int alpha = in.nextInt();
		objectDeck.create(alpha, ourDeck, suits, rank);
		in.close();
 
	}
}

public class Deck {
 
	public int stack(int[] ourDeck) {
		int i = 0;
		for (i = 0; i < ourDeck.length; i++) {
			ourDeck[i] = i;
		}
		return i;
 
	}
 
	public int flush(int[] ourDeck) {
		int index = 0;
 
		for (int i = 0; i < ourDeck.length; i++) {
			ourDeck[i] = i;
 
			for (int k = 0; k < ourDeck.length; k++) {
				index = (int) (Math.random() * ourDeck.length);
				int temp = ourDeck[k];
				ourDeck[k] = ourDeck[index];
				ourDeck[index] = temp;
			}
		}
		return ourDeck[index];
	}
 
	public int create(int Mnumber, int[] k, String[] suits, String[] rank) {
 
		int counter = 0;
		for (int i = 0; i < Mnumber; i++) {
			String Suit = suits[k[i] / 13];
			String Rank = rank[k[i] % 13];
			counter++;
			System.out.println("Card number is " + k[i] + " : " + Rank + " of " + Suit);
			if (counter == Mnumber) {
				System.out.print("And there are " + (52 - Mnumber) + " cards left!");
			}
		}
		return counter;
 
	}
}

Create a class Card, representing a playing card in an ordinary card deck with 52 cards. A card has a suite (4 different) and a rank (13 different). Write a class Deck initially containing 52 different objects of the class Card. The class Deck should contain methods for shuffling the deck, deal a card and telling how many cards are still in the deck. Note that it should only be possible to shuffle a deck if it contains 52 cards. (Information at Wikipedia about card decks and card games.)

Also write a program PlayCardsMain, creating a card deck and dealing some cards, telling the number of remaining cards and which cards that have been dealt.

Hint: Use enumeration types.

I already have a class called DeckMain that does everything within itself.

I recommend you check the tutorials link in my signature below to learn more about them. My take on the assignment was that you could use enums if you want but they aren't required.

I will check it out!
Thanks jim.
