This is not really on-topic but does have ramifications for what
we're all talking about so...

Empty java.lang.String==""
You can tell that because "".length()==0
Whereas: " ".length()==1 (the space)
But that probably shouldn't affect the code as long as you are
comparing like with like,
ie:
" ".equals(" ");
or
"".equals("");
With the empty string you can always do:
"".length()==0
which is probably more efficient (because the compiler can inline the
call to length()).
IMHO in Java generally you should always use a null guard with
Strings, eg:
if(string!=null && string.length()!=0)
//it's not a null or empty string
