There are already many useful ways to obtain and compose URLs in the
core Java API. For example, if you are getting your image from a
file, you can construct a File object representing your base path,
and then use the File(File, String) constructor to obtain various
relative paths off that. File has a handy toURL() method that will
get you the URL you need. Similarly, you can construct a base URL
class and then construct relative paths from it. Finally, consider
the Class.getResource(String) method (which returns an URL) as a
great way to locate image files in a portable manner that will not
need to change regardless of whether your image in an a file system,
packed into a JAR file, or even being fetched across the network.
Consult the core API Javadoc for more information.
