The difference seem to be StringBuilder being non-synchrinized and StringBuffer being synchronized. But I am not getting a clear idea on how it works.Can I please get a simple example to start getting the concept correct?
This class provides an API compatible with StringBuffer, but with no guarantee of synchronization. This class is designed for use as a drop-in replacement for StringBuffer in places where the string buffer was being used by a single thread (as is generally the case). Where possible, it is recommended that this class be used in preference to StringBuffer as it will be faster under most implementations.
