This stream is piped in the reading process, any characters read are written
to an associated OutputStream
object.

. If no byte is available because the end of the
stream has been reached, the value -1
is returned. This
method blocks until input data is available, the end of the stream is
detected, or an exception is thrown.
A subclass must provide an implementation of this method.

len
bytes of data from this input stream into
an array of bytes. This method blocks until some input is available.
This method simply performs in.read(b, off, len)
and
returns the result.
