Get file name from a file location in Java

Question

I have a String that provides an absolute path to a file  including the file name   I want to get just the file s name  What is the easiest way to do this   It needs to be as general as possible as I cannot know in advance what the URL will be  I can t simply create a URL object and use getFile   - all though that would have been ideal if it was possible - as it s not necessarily an http    prefix it could be c   or something similar

new File fileName  getName      or  int idx   fileName replaceAll              lastIndexOf       return idx  gt   0   fileName substring idx   1    fileName    Notice that the first solution is system dependent  It only takes the system s path separator character into account  So if your code runs on a Unix system and receives a Windows path  it won t work  This is the case when processing file uploads being sent by Internet Explorer
