    Did you click the link? An SSCCE is a short, self-contained, compilable example. That means, narrow your problem down to just a few lines- in this case, the displaying of an image. It should be one complete file, and it should not include any extra stuff other than displaying an image.

    Also, answer the questions you've already been answered- Norm is being extremely patient with you, and you should repay him by answering his questions as accurately as you can.

    That's part one. Where is this part?

    Open a command prompt window, change to the folder with the images and enter the command: dir
    Copy and paste the contents here:
    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show

    What did google tell you? Wanting to learn and get help is one thing, but you have to put an effort into figuring things out.

    In the command prompt window use the cd command to change directories.
    Here is a sample of its usage:
     
    D:\JavaDevelopment\Testing>cd ..
     
    D:\JavaDevelopment>cd Testing
     
    D:\JavaDevelopment\Testing>cd Security
    The system cannot find the path specified.
     
    D:\JavaDevelopment\Testing>cd images
     
    D:\JavaDevelopment\Testing\images>dir
     Volume in drive D is Work
     Volume Serial Number is 1463-F5AE

    Your code has: " images/Track.gif"

    the image file location: C:\Users\Daniel\Pictures>

    These are not the same!!! They must be the same.

    Your program must have the path to where the image files are located on your computer.
    You can use relative paths such as: images/<theImage>

    Either move the images or change the name of the folder, or change the code.
    Whatever you want to do so that the path in the program matches the path to the files on your computer.
    If you don't understand how the folders and files are arranged on your computer, there is nothing I can do to help you. This is a very basic concept: Folders and subfolders and files.

    You'll some things for the cars to move.
    The first would be a timer that will change their x,y position every small unit of time.
    The second would be a definition of where the track is. This will require a lot of x,y positions to define the boundary of the track so you know when to go around curves etc.

    Here is my latest modified code :

    Would you mind to help me with it..??
    Because this x,y positions I was not really good in doing it to move them around the curves..

    How are you changing the x,y positions of the cars as they move?
    How are you defining the x,y positions of the curves

    I defined it as Xpos =30 and Ypos = 30..
    After that I use the drawImage method to draw out the components of the cars and its x,y positions..
    This is the part I was very confusing while I was doing this project..

    I think it might be useful for you in learning how to animate your program to look at one of the many bouncing ball programs that exist. Search on this forum or google for example codes that will help you understand how to use a timer and how to change the values of x,y to do the animation.

    You need to concentrate on the animation part only. The rest of your code would be in the way.
    Start with using a Swing Timer to change the x,y positions of the images and then call repaint() to show the changes.

    That is absolutely not how this works. Norm has been kind enough to hold your hand up until this point, but you're going to have to show some effort if you want more help. What have you tried? What did google tell you? Where are you stuck? Where's your SSCCE?
