The apache Commons library has
FilenameUtils.getExtension().You can look over the source starting here, and FilenameUtils.
At least look over their implementation. It’s pretty simple, they handle dir.ext/file correctly, and to handle something like file.tar.gz you’ll need a special case if you want to extract .tar.gz rather than just .gz.
