Java in a Nutshell, 5th Edition [Electronic resources]

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.
