    Default Image not diplaying in Jframe. Is there anything wrong in my Code?

    I have made this code watching video from youtube. But my JFrame does not display anything. I have three class as follow and images are Mario_Back.jpg with 1200X300 and Stick.gif with 400X400 in the same directory. Can anyone help me?

    -------------------------------------------------------------------------------------------------------------------------------------
    Frame.java
    --------------------------------------------------------
    package TryGame;

    import javax.swing.JFrame;

    public class Frame {
    public static void main(String args[])
    {
    JFrame frame = new JFrame("Survival");
    frame.add(new Board());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
    frame.setSize(1200,300);
    frame.setVisible(true);

    }

    }
    ------------------------------------------------------------------------------------------------------------------------------------
    Dude.java
    ----------------------------------------------
    package TryGame;

    import java.awt.Image;
    import java.awt.event.KeyEvent;
    import javax.swing.ImageIcon;

    public class Dude
    {
    int x,dx,y;
    Image still;

    public Dude()
    {
    ImageIcon i = new ImageIcon("Stick.gif");
    still = i.getImage();
    x = 10;
    y = 172;
    }
    public void move()
    {
    x = x + dx;
    }
    public int getX()
    {
    return x;
    }
    public int getY()
    {
    return y;
    }
    public Image getImage()
    {
    return still;
    }
    public void keyPressed(KeyEvent e)
    {
    int key = e.getKeyCode();
    if(key == KeyEvent.VK_LEFT)
    {
    dx = -1;
    }
    if(key == KeyEvent.VK_RIGHT)
    {
    dx = 1;
    }
    }
    public void keyReleased(KeyEvent e)
    {
    int key = e.getKeyCode();
    if(key == KeyEvent.VK_LEFT)
    {
    dx = 0;
    }

    }

    }
    }

    p = new Dude();
    addKeyListener(new AL());
    setFocusable(true);
    ImageIcon i = new ImageIcon("Mario_Back.jpg");
    img = i.getImage();
    time = new Timer(5, this);
    time.start();
    }

    @Override
    public void actionPerformed(ActionEvent e) {
    p.move();
    repaint();
    }

    public void paint(Graphics g)

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    You should override the paintComponent() method for Swing classes, not the paint() method.
    If you don't understand my answer, don't ignore it, ask a question.
