This abstract class is the
superclass
of all output streams. It defines the basic output methods all output
stream classes provide. write( ) writes a
single byte or an array (or subarray) of bytes.
flush( ) forces any
buffered output to be written. close( ) closes the
stream and frees up any system resources associated with it. The
stream may not be used once close( ) has been
called. See also Writer.
