Fails on some inputs,
June 24, 2010 at 1:51 PM

eg ".htaccess" or "noextension"

Here's a fixed version:

// default in case there's no extension:
String baseName = fileName;
String extension = "";
// split on position of dot in name
int lastDotPos = fileName.lastIndexOf(".");
if(lastDotPos>=0 && fileName.length()>lastDotPos) {
baseName = fileName.substring(0,lastDotPos);
extension = fileName.substring(lastDotPos+1,fileName.length());
}
