Java in a Nutshell, 5th Edition [Electronic resources]

This class is a subclass of OutputStream in which output data is stored in an internal byte array. The internal array grows as necessary and can be retrieved with toByteArray( ) or toString( ). The reset( ) method discards any data currently stored in the internal array and stores data from the beginning again. See also CharArrayWriter.
