Why isn't my JComponent being painted onto JFrame

Question

I am using the Card class from Sun's enum examples. The Card class extends JComponent and each card has an Image field storing its graphic. My problem is that when getContentPane().add(card) is called, it doesn't show up on the JFrame. I have overridden paint() in both the Card class and JFrame to see if either will work, but they haven't. I'd appreciate any help.

import javax.swing.JComponent;
public class Card extends Component {
    public enum Rank {
        DEUCE (2),

        SIX (6),
        SEVEN (7),
        EIGHT (8),
        NINE (9),
        TEN (10),
        JACK (10),
        QUEEN (10),
        KING (10),
        ACE (11, 1);
private final int value1, value2;
    Rank (int val) {
    this.value1 = val;
    this.value2 = 0;
    Rank (int val, int val2) {
    this.value1 = val;
    this.value2 = val2;
public int val1() { return this.value1; }
public int val2() { return this.value2; }
    public enum Suit { CLUBS, DIAMONDS, HEARTS, SPADES }
    private final Rank rank;
    private final Suit suit;
    private Image image;
    private static final List<Card> protoDeck = new LinkedList<Card>();
    public Card(Rank rank, Suit suit, String img) {
        super();
        this.rank = rank;
        this.suit = suit;
        this.image = Toolkit.getDefaultToolkit().createImage(img);
// is the below method implementation right?
public void paint(Graphics g) {
boolean x = g.drawImage(image, 0, 0, null);
    public Rank rank() { return rank; }
    public Suit suit() { return suit; }
    public Image getImg() { return this.image; }
    public String toString() { return rank + " of " + suit; } 
    // Initialize prototype deck
    static {
        for (Suit suit : Suit.values()) {
            for (Rank rank : Rank.values()) {
                String imgPath = "C:/Documents and Settings/Administrator/Desktop/java/BlackJack/" + rank + suit + ".jpg";
                protoDeck.add(new Card(rank, suit, imgPath));

Answer 1

Never override the painting methods of your top level contaier (ie. JFrame).
Custom painting is done by overriding the paintComponent(...) method of JComponent or JPanel.
So because you are using the Card class in a Swing application you need to extend JComponent as suggested above and override paintComponent(...), not paint(...);
Also why do you think you even need to override any paint method to draw the cards. Just add you Cards to a panel using a null layout. Read the Swing tutorial on layout managers, specifically the section on "Absolute Positioning";
http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html
Better yet use the appropriate combination of layout managers to get your desired look so you don't need to worry about a null layout.
