reader/writer support only cahracter and input/output
stream support only bytes input stram and the java reader
class has only one differnce and that is input stream only
support bytes and the reader class only supports the
These are IO streams but difference their
InputStream/OutputStreams class are byte-oriented
streams.this streams read and write in byte oriented.
InputStream/OutputStreams are never support unicode characters.
Reaer/writer class are belongs to the charecter stream
this streams read and write in character oriented Streams .
Reaer/writer are never supports unicode characters.
The Reader/Writer class hierarchy is character-oriented, and
the Input Stream/Output Stream class hierarchy is byte-oriented.
Basically there are two types of streams.Byte streams that
are used to handle stream of bytes and character streams for
handling streams of characters.In byte streams input/output
streams are the abstract classes at the top of
hierarchy,while writer/reader are abstract classes at the
top of character streams hierarchy.
