Split string with dot as delimiter

Question

I am wondering if I am going about splitting a string on a . the right way? My code is:

String[] fn = filename.split(\".\");
return fn[0];

Using ApacheCommons it's simplest:

File file = ...
FilenameUtils.getBaseName(file.getName());

Note, it also extracts a filename from full path.
