Simple ArrayList Q

[melbourn1te]

Hi,

I hope this is an easy question to answer for you.

I am making a card game that has a Card class and a Deck class. I am using an ArrayList to represent the cards in the deck, but I'm unsure on one particular part of the code.

public class Deck {

	private ArrayList<Card> deck;
	private Card[] initialDeck; 

	/**
	 * Create a new deck from an initial set of cards.
	 * 
	 */
	public Deck(Card[] initialDeck)  {
		super();
		this.initialDeck = initialDeck;
		deck = new ArrayList<Card>();

This is what I have so far, what is confusing me is how initialDeck is a parameter in the constructor. Is this meant to be used in the ArrayList and if so, how do I do this?

Thanks in advance if you can help!

Sorry, but your question doesn't make any sense. Yes initialDeck is a parameter, is what meant to be used in the ArrayList?

Card[] is an Array of Card
deck is an ArrayList of Card

Are you intentionally using a mix of both?

to add an Array to ArrayList use java.util.Arrays.asList e.g.

Card[] initialDeck = new Card[52];
java.util.List<Card> cardList = new java.util.ArrayList<Card>();
cardList.addAll(java.util.Arrays.asList(initialDeck));

Thank you so much for the help.

The mix is intentional as far as I am aware, we were given a stubbed implementation to expand on, so the Arrays.asList worked perfectly.

Thank you again!
