Thread: Printing From Another Class.

I am trying to print from a different class, and this is my current code. The last code entry is the mainclass, and "Card" is showing up as cannot find symbol error. I am trying to print printCard using variables (1, 11).

public class CardWork {
 
 
    /*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
 
/**

 * @author Logan
 */
public class Card {
    int suit, rank;
 
    public Card () {
        this.suit = 0; this.rank = 0;
    }
 
 
 
    public void printCard (Card c) {
        String[] suits = { "Clubs", "Diamonds", "Hearts", "Spades" };
        String[] ranks = { "narf", "Ace", "2", "3", "4", "5", "6",
"7", "8", "9", "10", "Jack", "Queen", "King" };
 
    System.out.println (ranks[c.rank] + " of " + suits[c.suit]);
 
}
 
 
}
 
}

And this is my mainclass

public class Cards {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Card card = new Card (1, 11);
        printCard (card);
 
    }
}

printCard is not a method of Cards, but the way you are calling it is as if you assume that it was a static method of this class. No, you need to call this method off of a Card instance, here off of the card variable.

So the method should be called like so:

   card.printCard();

Note, this method should not take a parameter as it is printing the current card object, not some Card that you pass into it.

Hello Curmudgeon, what if I want to pass (1, 11) into the method printCard? Would I add (1, 11) into the printCard method?

--- Update ---

Also, in main I have tried adding card.printCard(); and it is telling me card is not a symbol.

This doesn't make sense. The method printCard() should print the current card, and that's it. It shouldn't be used to set fields in a Card object or anything else. It should just print the Card, period.

[/COLOR]Also, in main I have tried adding card.printCard(); and it is telling me card is not a symbol.

Because you need to change the method in Card so that it takes no parameters.

I have tried removing the parameters and still I am getting cannot find symbol on card.printCard();

public class Card {
    int suit, rank;
 
    public Card () {
        this.suit = 0; this.rank = 0;
    }
 
 
 
    public void printCard () {
        String[] suits = { "Clubs", "Diamonds", "Hearts", "Spades" };
        String[] ranks = { "narf", "Ace", "2", "3", "4", "5", "6",
"7", "8", "9", "10", "Jack", "Queen", "King" };
 
    System.out.println (ranks[c.rank] + " of " + suits[c.suit]);
 
 
 
}
 
 
}
 
}

public class Cards {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        card.printCard();
 
 
    }
}

Fixed the issue. Thanks Cur.
