Image path in Java

I am creating a batch file which contains a button with image. While running the application in my PC, the image is displayed correctly. But whenever the file is run on a different PC, the image is not displayed. Only the button is shown. 

To display the image without explicitly writing where the file is located, you can create a package within the project and copy the images to that package. Then compile and execute the jar file in any PC. The image will be displayed.
