This class applies buffering to a
character output stream, improving output efficiency by coalescing
many small write requests into a single larger request. You create a
BufferedWriter by specifying some other character
output stream to which it sends its buffered and coalesced output.
(You can also specify a buffer size at this time, although the
default size is usually satisfactory.) Typically, you use this sort
of buffering with a FileWriter or
OutputStreamWriter.
BufferedWriter defines the standard
write( ), flush( ), and
close( ) methods all output streams define, but it
adds a newLine( ) method that outputs the
platform-dependent line separator (usually a newline character, a
carriage-return character, or both) to the stream.
BufferedWriter is the character-stream analog of
BufferedOutputStream.
