Help With 5 card stud program

Hi all. I'm Looking for some assistance on a 5 card stud poker program. So far I can shuffle and deal, now I am trying to evaluate the hands each player gets. I was shown how to do this, but forgot. I'm a total beginner at programming. First, I am not sure if I am filling the arrays hand1 and hand2 correctly, can someone help me confirm that they are filled. Second, I've been trying to get one of the text fields to simply show the face and suit of the card in position tthree of hand one, I can't get it to show the string. Last, I am pretty sure i can figure out the algorithms for my method handEval, yet once again need to check and make sure the array is filled.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class poker2 extends JFrame {
private Card deck[]; //this is an array of objects of Card type. See the Card class at the end
private int currentCard; //this keeps track of the number of cards dealt
private JButton dealButton, shuffleButton, testButtton; //GUI stuff, the two buttons
private JTextField displayField; //GUI stuff, the textfield that displays the card dealt
private JLabel statusLabel; //GUI stuff, Displays the number of cards dealt
private JLabel cardback, card1, card2,card3,card4,card5,card6,card7,card8,card9,card10;//GUI stuff The labels that displays the cards

The class name is "poker3". In the main method you are creating an instance of "poker"; not the same class.
To check the "hand1" and "hand2" arrays you could make up a method to print out their values to the console and call it wherever you like inside your event code. For starters you could call it at the end of the shuffle event handler (shuffleButton anonymous ActionListener "actionPerformed" method) and again in the deal event handler (dealButton anonymous ActionListener "actionPerformed" method). You could try something like this to start with

or, if using j2se 1.5+ we have java.util.Arrays.toString(hand1)
Place the showHands method as an instance method of "poker3", ie, on the same level as the shuffle and showcard methods vis–a–vis inside an anonymous ActionListener class. Then anyone can call it.
A couple of other ideas:
1 — you only need to load the "card" ImageIcon one time.
2 — in the Card class you have the viewcard method that returns a String representation of the Card. If you change the name of the method to "toString" then java will automatically call this method when you use a Card instance variable by itself, eg,

This is called overriding the "toString" method.
 
I agree. Here's the link: http://aspose.com/file-tools
