grabbing the name of a file

I need to grab the name of an image file stored in a folder, so that I can parse the name of the file.

C:\images\test.jpg

File.getAbsolutePath()

File f = new File("C:\\images\\test.jpg");
f.getName();

>> f.getName();
Do you need the name of the file given the full path?

f.getName();
will give you name of the file and f.getParentFile().getName(); will give parent directory.

f.getParent() will also return the name of the parent directory

If I had a file (NCWV10024.jpg) I need to parse out 10024 as it is the identification number. An easy method to grab this was desired.

If it's always the last 5 characters of the "stem name" you might:

String s = "NCWV10024.jpg";
int dot = s.indexOf('.'); // check?

String parsed = s.subString(4, dot);

There you are.
;JOOP!
