Java in a Nutshell, 5th Edition

Name

StringBuilder

Synopsis

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.
