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 .
