StringBuffer append("")

Question

I'm currentlly refactoring an application using a lot of this:

StringBuffer buff1 = new StringBuffer("");

buff1.append("some value A");
buff1.append("");
buff1.append("some value B");

The coder that made those code lines didn't seems to be an idiot, is there any reasons I can't see to use the append("") to a StringBuffer?

Answer 1

Nope.

And given that they're hardcoded strings, it'd be identical to write

buff1 = new StringBuffer("some value Asome value B");

BTW, it's a bit more efficient to use a StringBuilder rather than a StringBuffer (and the API is identical).
