    Here is the code:
    import javax.swing.*;
    import java.awt.geom.*;
    import java.awt.*;
    public class RaceTrack extends JFrame
    {
    private RaceTrackPanel animation;
    private JLabel betLabel, potLabel, bankLabel, carLabel;
    private JTextField betField, carField, potField, bankField, winnerField;
    private JButton goButton;
    private JPanel p;
    public RaceTrack( )
    {
    Image Track = new ImageIcon("Track.gif").getImage();
    Image Car1 = new ImageIcon("Redcar.gif").getImage();
    Image Car2 = new ImageIcon("Bluecar.gif").getImage();
    animation = new RaceTrackPanel(this, Track, Car1, Car2);
    Container c = getContentPane();
    c.setLayout(new BorderLayout( ));
    p = new JPanel( );
    p.setBackground(Color.lightGray);
    GridBagLayout grid = new GridBagLayout();
    p.setLayout(grid);
    betLabel = new JLabel("Enter Bet");
    carLabel = new JLabel("Choose Car");

    potField = new JTextField(5);
    bankField = new JTextField(7);
    winnerField = new JTextField(20);
    potField.setEditable(false);
    bankField.setEditable(false);
    goButton = new JButton("Start Race");
    GridBagConstraints gbc = new GridBagConstraints( );
    gbc.fill = GridBagConstraints.BOTH;

    I can't display the track eventhough I have declared it
    To see a component in a GUI display you need to add that component to a container that is being displayed with properties that the layout manager can use to position it and display it.
    Just declaring it will not display it.

    Please wrap your posted code in code tags. See: BB Code List - Java Forums

    Please explain what the error is.
    When I compile and execute the program (using some of my images) the 3 images are displayed.

    it can't display the track
    What is "the track"?
    There are three images referred to in the program. Is it one of those?
    Do any of the images display? What is different between the ones that display and the ones that do not display?

    Can you display any of the images with any program? Which ones display and which ones do not?

    Do any of the images display in your program?

    Sorry, I can not help you find the images you need.
    When you get the images you need for your program, then we can help you fix your program to do what you want.

    none of the images was displayed..
    Then the images are not in the correct folder.
    If you are using an IDE I can't help you.

    This is like some kind of puzzle game where you have to figure out the OPs problem from a few vague answers...

    Am I right in thinking that you actually have three images, of a track and two cars (which you don't like), and your program displays the track image, but it doesn't display the two car images, and if your code was written properly it would display them?

    I think it is an IDE configuration problem. The OP mentioned a "build" folder.
    He needs to find out where the IDE has the current directory when it executes and put the images there.
