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.
public synchronized void write(byte b,
int len) throws IOException
Writes len bytes from the specified byte array
starting at offset off to this buffered output stream.
Ordinarily this method stores bytes from the given array into this
stream's buffer, flushing the buffer to the underlying output stream as
needed. If the requested length is at least as large as this stream's
buffer, however, then this method will flush the buffer and write the
bytes directly to the underlying output stream. Thus redundant
BufferedOutputStreams will not copy data unnecessarily.
