Java 1.1

appendable closeable flushable

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 .
