This class defines the same methods as
StringBuffer but does not declare those methods
synchronized, which can result in better
performance in the common case in which only a single thread is using
the object. StringBuilder is a drop-in replacement
for StringBuffer and should be used in preference
to StringBuffer except where thread safety is
required. See StringBuffer for an overview of the
methods shared by these two classes.
