BufferedInputStream
A BufferedInputStream adds functionality to another input stream-namely, the
ability to buffer the input and to support the mark and reset
methods. When the BufferedInputStream is created, an internal buffer array is created. As bytes
from the stream are read or skipped, the internal buffer is refilled as
necessary from the contained input stream, many bytes at a time. The mark operation remembers a point in the input stream and the reset operation causes all the bytes read since the most recent mark operation to be reread before new bytes are taken from the
contained input stream.
BufferedOutputStream
The class implements a buffered
output stream. By setting up such an output stream, an application can write
bytes to the underlying output stream without necessarily causing a call to the
underlying system for each byte written.
