public class BufferedOutputStream
extends FilterOutputStream
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. The data is written into a buffer, and then written to the underlying stream if the buffer reaches its capacity, the buffer output stream is closed, or the buffer output stream is explicity flushed.
