I believe that what you (and Mark) suggest is functionally equivalent
to what the original poster had, but they are less efficient, because
there is more object creation going on (and superfluous object
creation at that). So they are unnecessary and less preferred.
Like I said before (or tried to say :-), double quoted string literals
should be perfectly acceptable whereever a String object can be (and a
String is an Object).
