String variable problem

[gkoef]

First I will show you the coding (with errors ) below:

import java.util.*;

public class Deck
{


	private Card[][] playingcards;

	public Deck(String rank, String suit)
	{
		for(rank = Card.CardRank[0]; rank [COLOR="Red"]<=[/COLOR] Card.CardRank[11]; rank[COLOR="Red"]++[/COLOR])
		{
			for(suit = Card.CardSuit[0]; suit [COLOR="Red"]<=[/COLOR] Card.CardSuit[3]; suit[COLOR="Red"]++[/COLOR])
			{
				//playingcards = new Card[rank][suit];	
			}
		}	

	}
}

The errors above are all to do with that CardSuit and CardRank are String arrays in another class called Card.

Is there any way in which I can change <= and ++ for String variables? or is it possible to convert a string of variables in an array to int variables without typing out each variable to int?

Playing cards have become a canonical example for the use of enums. Read this article.

I've added code tags to your first post so that the code is readable. Please read the link in my signature below to learn how to do this yourself.

I think that your problem comes from trying to use <= and such on Strings, but can't tell for sure without the actual error messages -- so please post these. If I'm right, then a solution is to loop on the int indexes and then use them inside the loop, something like this:

		for(int rank = 0; rank < 13; rank++)
		{
			for(int suit = 0; suit < 4; suit++)
			{
				playingcards[rank][suit] = new Card(Card.CardRank[rank], Card.CardSuit[suit]);
			}
		}

But having said this, Jos is right. This problem is taylor-made to be solved by enums.

I remember that in the exercise it states to keep the coding for the Enum tutorial lesson which is going to discussed later in the tutorial. But isn't it strange to give an exercise for something that has not been taught yet?

No, there's nothing strange about it. Just because it is most cleanly solved as an enum, doesn't mean that it can't be solved well by other techniques. If you haven't studied enums yet, don't use them, but also don't try to use Strings as the indices of your for loop.
