A step back in a path hierarchy

Question

I have a path to a folder and want to change it. But first I want to get a step back.

String path = "C:\Users\Jurgen\Java\Project\Folder\inner_folder\";

How do I get a step back in a path hierarchy? For example:

String path = "C:\Users\Jurgen\Java\Project\Folder\";

Answer 1

Extract a substring up until the last slash

String newPath = path.substring(0, path.lastIndexOf('\'));

Edit: (because I'm being challenged on this answer)

Some people will tell you that treating paths as strings is wrong, in this case it doesn't make a difference. The other option of creating a Path object then using it's .getParent() method or prior to Java 7, a File object.
