Reads the next byte of data from the input stream. The value byte is returned as an
int in the range
0 to
255 . 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.
