, Stream Classes
) The stream classes can be categorized into two types:
byte streams and character streams.
) The InputStream/OutputStream class is the
root of all byte stream classes, and the Reader/
Writer class is the root of all character stream
classes. The subclasses of InputStream/
OutputStream are analogous to the
subclasses of Reader/Writer.
