Java: splitting the filename into a base and extension

Question

Is there a better way to get file basename and extension than something like

File f = ...
String name = f.getName();
int dot = name.lastIndexOf(\'.\');
Strin         


        

Answer 1

What's wrong with your code? Wrapped in a neat utility method it's fine.

What's more important is what to use as separator — the first or last dot. The first is bad for file names like "setup-2.5.1.exe", the last is bad for file names with multiple extensions like "mybundle.tar.gz".
