This class is a FilterOutputStream that provides output data buffering; output efficiency is increased by storing values to be written in a buffer and actually writing them out only when the buffer fills up or when the flush( ) method is called. Create a BufferedOutputStream by specifying the OutputStream that is to be buffered in the call to the constructor. See also BufferedWriter.
