If you read Paul's statement as "0 object creations at runtime" it makes much
more sense. Essentially, string constant "objects" are created at compile
time, and are preloaded with the byte codes when you first load the class. The
other assumption is that variableX already exists because you needed it for
something, so the act of calling out.print doesn't create a new one.
