This class is a
FilterInputStream that provides input data
buffering; efficiency is increased by reading in a large amount of
data and storing it in an internal buffer. When data is requested, it
is usually available from the buffer. Thus, most calls to read data
do not actually have to read data from a disk, network, or other slow
source. Create a BufferedInputStream by specifying
the InputStream that is to be buffered in the call
to the constructor. See also BufferedReader.
