Answer 1

Change / for \ if you are using windows.

A more cross-platform approach would be substitute

C: for File.listRoots()[0] and every / for File.separator.

EDIT

(I didn't read this line, sorry)

This code was running properly untill i try to read an image from the source package

In order to get a file from inside your jar package, one must use the getClass().getResource() method.

Example:

application-package:
|-Main.java
|-resources
  |-image.jpg

For the above directory structure:

BufferedImage im = ImageIO.read(new File(getClass().getResource("/resources/image.jpg").toURI()));

Would do the trick.
