class whose instances represent a full deck of cards

[Vneha]

[code=java]import java.util.*;

public class Deck {

public static int numSuits = 4;
public static int numRanks = 13;
public static int numCards = numSuits * numRanks;

private Card[][] cards;

public Deck() {
cards = new Card[numSuits][numRanks];
for (int suit = Card.DIAMONDS; suit <= Card.SPADES; suit++) {
for (int rank = Card.ACE; rank <= Card.KING; rank++) {
cards[suit-1][rank-1] = new Card(rank, suit);
}
}
}

public Card getCard(int suit, int rank) {
return cards[suit-1][rank-1];
}
}[/code]


Q:- Why this expression (cards[suit-1][rank-1] = new Card(rank, suit); ) is added?

[JosAH]

Most likely Card.DIAMONDS and Card.ACE (the lowest values) are defined as 1.
Index values start at 0. Quite clumsy if you'd ask me.

kind regards,
