Java In A Nutshell, 5th Edition

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 .
