Question

What would be the most efficient way to cover all cases for a retrieve of folder1/folder22

from:

http://localhost:8080/folder1/folder22/file.jpg
or
http://domain.com/folder1/folder22/file.jpg
or
http://127.0.0.0.1:8080/folder1/folder22/file.jpg

so there may be one or more folders/sub-folders. Basically I would like to strip the domain name and port if available and the file name at the end.

Thank for your time.

What about the URL class and getPath()?

Maybe it’s not the most efficient way, but one of the simplest I think:

String[] urls = { 
  "http://localhost:8080/folder1/folder22/file.jpg", 
  "http://domain.com/folder1/folder22/file.jpg",
  "http://127.0.0.0.1:8080/folder1/folder22/file.jpg" };
for (String url : urls)
  System.out.println(new File(new URL(url).getPath()).getParent());
