I am having problems getting this DeckOfCards class to compile. It keeps telling me that it cannot find the symbol when pointing to Deck2.Shuffle() and Deck2.deal(). Any ideas why?
import java.lang.Math;
import java.util.Random;
public class DeckOfCards {
private Cards[] Deck;
private int cardHold;
public DeckOfCards() {
Deck = new Cards[52];
int n = 0;
for (int i = 1; i <= 13; i++) {
for (int j = 1; j <= 4; j++) {
Deck[n] = new Cards(i, j);
n = n + 1;
}
}
cardHold = -1;
}
public void Shuffle() {
// shuffles ands resets deck
int i = 0;
while (i < 52) {
int rando = (int) (5.0 * (Math.random()));
Cards temp = Deck[rando];
Deck[rando] = Deck[i];
Deck[i] = temp;
i++;
}
}
public Cards deal() {
// if there are any more cards left in the deck, return the next one and
// increment
// index; return null if all the cards have been dealt
// ***Question, increment before or
// after??***----------------------------------------
if (!hasMoreCards()) {
return null;
} else {
Cards temp = null;
temp = Deck[cardHold];
cardHold = cardHold + 1;
return temp;
}
}
public boolean hasMoreCards() {
// returns true if there are more cards left, else return false
if (cardHold == 0)
return false;
else
return true;
}
public static void main(String[] args) {
DeckOfCards Deck2 = new DeckOfCards();
Deck2.Shuffle();
for (int i = 0; i < 52; i++)
System.out.println(Deck2.deal());
}
}
Below class is Card class, maybe that is causing the issue?
public class Cards {
protected int rank;
protected int suit;
protected String[] sNames = { "Hearts", "Clubs", "Spades", "Diamonds" };
protected String[] rNames = { "Ace", "2", "3", "4", "5", "6", "7", "8",
"9", "10", "Jack", "Queen", "King" };
public Cards(int Rank, int Suit) {
suit = Suit;
rank = Rank;
}
public String toString() {
return ("Your card is: " + rNames[rank - 1] + " of " + sNames[suit - 1]);
}
public int getRank() {
return rank;
}
public int getSuit() {
return suit;
}
}
Your compiler issues are behind you, but there are lots of issues with your code.
public class DeckOfCards {
private Cards[] deck;
private int cardHold;
public DeckOfCards() {
deck = new Cards[52];
int n = 0;
for (int i = 1; i <= 13; i++) {
for (int j = 1; j <= 4; j++) {
deck[n] = new Cards(i, j);
n = n+1;
}
}
cardHold = -1;
}
public void shuffle() {
int i = 0;
while (i < 52) {
int rando = (int) (5.0*(Math.random()));
Cards temp = deck[rando];
deck[rando] = deck[i];
deck[i] = temp;
i++;
}
}
public Cards deal() {
return (hasMoreCards() ? deck[++cardHold] : null);
}
public boolean hasMoreCards() {
return (cardHold != 0);
}
public static void main(String[] args) {
DeckOfCards deck2 = new DeckOfCards();
deck2.shuffle();
for (int i = 0; i < 52; i++)
System.out.println(deck2.deal());
}
}
And:
public class Cards {
protected int rank;
protected int suit;
protected String[] sNames = {"Hearts", "Clubs", "Spades", "Diamonds"};
protected String[] rNames = {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King"};
public Cards(int rank, int suit) {
this.suit = suit;
this.rank = rank;
}
public String toString() {
return ("Your card is: "+rNames[rank-1]+" of "+sNames[suit-1]);
}
public int getRank() {
return rank;
}
public int getSuit() {
return suit;
}
}
You are using an assignment operator in the if statement expression here:
if (cardHold = 0)
Replace with
if (cardHold == 0)
you may want to add import java.util.Date; and the shuffle function and call in the main is different one have 's'and the other 'S'.
Try this:
import java.lang.Math;
import java.util.Date;
import java.util.Random;
public class DeckOfCards {
private Cards[] Deck;
private int cardHold;
private Random rand;
public DeckOfCards() {
rand = new Random();
Date d = new Date();
rand.setSeed(d.getTime());
Deck = new Cards[52];
int n = 0;
for (int i = 1; i <= 13; i++) {
for (int j = 1; j <= 4; j++) {
Deck[n] = new Cards(i, j);
n = n + 1;
}
}
cardHold = 0;
}
public void shuffle() {
// shuffles ands resets deck
int i = 0;
while (i < 52) {
// int rando = (int)(5.0 * (Math.random()));
int rando = rand.nextInt(52);
Cards temp = Deck[rando];
Deck[rando] = Deck[i];
Deck[i] = temp;
i++;
}
}
public boolean hasMoreCards() {
// returns true if there are more cards left, else return false
if (cardHold == 0)
return false;
else
return true;
}
public static void main(String[] args) {
DeckOfCards Deck2 = new DeckOfCards();
Deck2.shuffle();
for (int i = 0; i < 52; i++)
System.out.println(Deck2.Deck[i]);
}
}

I am trying to get my private void transfer method and pass it into a 2D array transfer2D method, after which I am able to print it out using the print2D_1 method. I am also trying to sort the array from the highest suit to the lowest suit followed by the highest rank to the lowest rank e.g. S12, S9, H13, D09, C10. Please advice.

Your transfer2D() method should look like this:
private void transfer2D(String[] strArray, String[][] twoD)
{
int i = 0;
for( int suit = 0; suit < 4; suit++ )
for( int rank = 0; rank < 13; rank++ )
twoD[suit][rank] = strArray[i++];
}
as a convention: outgoing values should appear at the end of the parameter list
I am hoping to get some help even though I know this is probably a very simple bug that I cannot seem to find an answer to.
What I am trying to accomplish is to create a deck of cards, and I keep running into an out of bounds error.
Here is my code:
Card Class:
public class Card {
private String suit;
private int face;
public Card(int face, String suit){
face = this.face;
suit = this.suit;
}
public int getFace(){
return face;
}
public String getFaceAsString(int face){
int faceName = face;
String faceString = "";
if(faceName == 11){
faceString = "J";
} else if(faceName == 12){
faceString = "Q";
} else if(faceName == 13){
faceString = "K";
} else if(faceName == 14){
faceString = "A";
} else {
faceString = Integer.toString(faceName);
}
return faceString;
}
public String getSuit(){
return suit;
}
public void setSuit(String suit){
this.suit = suit;
}
}
This is my main class:
import java.util.Random;
import java.util.Scanner;
public class Hero_Game {
public static void main(String[] args) {
String[] suits = {"Spades","Clubs","Hearts","Diamonds"};
int[] faces = {2,3,4,5,6,7,8,9,10,11,12,13,14,15};
int index = 0;
Card[] deck = new Card[52];
for(int i = 0; i<suits.length;i++){
for(int j = 0; j<faces.length;j++){
deck[index] = new Card(faces[i],suits[j]);
index++;
}
}
You switched the indexes for the faces and suits arrays in your for loops. It should be:
for(int i = 0; i<suits.length;i++){
for(int j = 0; j<faces.length;j++){
deck[index] = new Card(faces[j],suits[i]);
index++;
}
}
You also have an extra number in your "faces" array - you're trying to create 14 * 4 = 56 cards instead of 13 * 4 = 52.
Why do you have 14 faces instead of 13?
In any case, to more safely allocate the correct number of items in your deck array, use int numCardsInDeck = suits.length * faces.length; to calculate the total items in the deck.
Try this instead:
import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;
public class Game {
public static class Card {
final int face;
final String suit;
public Card(int face, String suit) {
this.face = face;
this.suit = suit;
}
#Override
public String toString() {
return face + " of " + suit;
}
}
public static void main(String[] args) {
String[] suits = {"Spades","Clubs","Hearts","Diamonds"};
int[] faces = {2,3,4,5,6,7,8,9,10,11,12,13,14};
int index = 0;
int numCardsInDeck = suits.length * faces.length;
Card[] deck = new Card[numCardsInDeck];
for(int i = 0; i < suits.length; i++) {
for(int j = 0; j < faces.length; j++) {
deck[index] = new Card(faces[j],suits[i]);
index++;
}
}
System.out.println(Arrays.toString(deck));
}
}
int[] faces = {2,3,4,5,6,7,8,9,10,11,12,13,14,15};
Get rid of 15 and do the loop as suggested by #Geshode
here is the code:
import java.util.Random;
public class Card{
private String rank;
private String suit;
private Card[] deck;
private int currentCard;
private static final int NCARDS = 52;
private static final Random randomNumbers = new Random();
private static String[] ranks ={ "2", "3", "4", "5", "6","7", "8",
"9", "10", "J", "Q", "K","A"};
private static String[] suits = { "Spades", "Heart", "Clubs", "Diamond" };
public Card(String rank,String suit)
{
this.rank = rank;
this.suit = suit;
}
public Card()
{
deck = new Card[ NCARDS ];
for ( int count = 0; count < deck.length; count++ )
deck[ count ] = new Card( ranks[ count % 13 ], suits[ count / 13 ]
}
public void shuffle()
{
for ( int first = 0; first < deck.length; first++ ){
int second = randomNumbers.nextInt( NCARDS );
Card temp = deck[ first ];
deck[ first ] = deck[ second ];
deck[ second ] = temp;
}
}
public String getSuit()
{
return this.suit;
}
public String getRank()
{
return this.rank;
}
public Card dealCard()
{
if(currentCard < deck.length)
return deck[currentCard++];
else
return null;
}
public String toString(){
return getRank() + " of " + getSuit();
}
//my sorting algorithm, couldn't work, still remain the same output
public void sortbyRank()
{
//how to compare suit since club is higher than diamond
for(int i=0; i<deck.length-1; ++i)
{
int min = i;
for(int j =i +1; j<deck.length ; ++j){
if(deck[j].getRank().compareTo(deck[i].getRank()) < 0)
{
min = j;
}
}
Card temp = deck[min];
deck[min] = deck[i];
deck[i] = temp;
}
}
all function works, but could sort after i compile the code, i need to compare to suit first then rank but i couldn't done the suit since the "Club" is greater than "Diamond" in this category.
First, thanks for reading this, I'm going to start by posting all code relevant to the program which you can skim or completely skip over for now.
Try to ignore all my sarcastic comments throughout the code btw they aren't directed at stack overflow :P

Anyways their are a few things that are very weird with the program that I can't seem to figure out. Sometimes the program will run fine and you can play a full game with lots of players but other times it throws a bunch of exceptions.
basically if you bust (go over 21) the program throws this 100% of the time:
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.rangeCheck(ArrayList.java:653)
at java.util.ArrayList.get(ArrayList.java:429)
at CardList.getCard(CardList.java:31)
at BlackJack.dealCard(BlackJack.java:151)
at BlackJack.dealerTurn(BlackJack.java:93)
at BlackJack.everyoneGo(BlackJack.java:138)
at BlackJack.main(BlackJack.java:209)
btw if someone could explain what it means by exceptions at lines that don't exist such as 653 (the first message) that would be very helpful.
It also throws the same exception some of the time even if you don't bust which I'm assuming is the dealer busting as the dealer plays automatically obeying the regular casino rules for dealers.
If anyone can figure it out it would be greatly appreciated, thanks!
I am trying to draw a Hand of Cards (in the Hand class) but have it shuffled. My problem is if I do shuffleDeck() in the initialDeal() method (where I need to draw a Hand of Cards but shuffled) it gives me an ArrayIndexOutOfBounds exception.
And I draw two narfs OF Clubs... Note, the narf is basically 0 and just a placeholder. It will not be used.
class Card {
int suit, rank;
public Card () {
this.suit = 0; this.rank = 0;
}
public Card (int suit, int rank) {
this.suit = suit; this.rank = rank;
}
public int getSuit() {
return suit;
}
public int getRank() {
return rank;
}
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[rank] + " of " + suits[suit]);
} //end printCard
} //end class
Card class(this is basically doing basic stuff) ^
import java.util.Random;
class Hand {
static Card[] deck = new Card[52];
Card[] hand = new Card[10];
static int index;
public static void createDeck () {
int m = 0;
for (int j = 0; j < 4; j++) {
for (int k = 1; k < 14; k++) {
deck[m] = new Card(j,k);
m++;
}
}
index = 0;
} // end createDeck
public static Card deal () {
Hand.index++;
return deck[index-1];
} // end deal
public static int compareCard (Card c1, Card c2) {
if (c1.getSuit() > c2.getSuit()) return 1;
if (c1.getSuit() < c2.getSuit()) return -1;
if (c1.getRank() > c2.getRank()) return 1;
if (c1.getRank() < c2.getRank()) return -1;
return 0;
} // end compareCard
public void printDeck (int size) {
int j = 0;
while (j < size) {
deck[j].printCard();
j++;
}
}// end printDeck
public static void shuffleDeck () {
Card tempCard;
Random rd = new Random();
for (index = 0; index < deck.length; index++) {
int r = rd.nextInt(deck.length);
tempCard = deck[index];
deck[index] = deck[r];
deck[r] = tempCard;
}
} // end shuffleDeck
public void initialDeal() {
hand[0] = null;
hand[1] = null;
hand[0] = deal();
hand[1] = deal();
}
public void printHand() {
initialDeal();
index = 0;
for(Card outputCard = new Card(); hand[index] != null; index++) {
outputCard.printCard();
}
}
}
Hand class^ (this is where I need to draw two cards from a shuffled deck)
class Dealer {
Hand dealer = new Hand();
public Dealer () {
dealer.createDeck();
dealer.shuffleDeck();
System.out.println("Dealer's Hand");
System.out.println("");
initDeal();
}
public void initDeal() {
dealer.initialDeal();
dealer.printHand();
}
} //end class
Dealer class.^ Calling the methods of Hand
class Driver {
public static void main (String[] args) {
Dealer dealer = new Dealer();
} //end main method
} //end class
^ Running everything basically
You're modifying the index in shuffleDeck, so after the shuffleDeck finishes, the index is shuffleDeck.length.
In shuffleDeck, do for (int index = 0; index < deck.length; index++)
(note the int index -> declare local variable, and not use the static one.)
Or you can (in initialDeal) set the index to 0.
