A mechanism for writing byte data to a stream

A ByteArrayOutputStream is a mechanism for writing an array of byte data to a stream. A stream is usually comprised of data to write to a local file, or data being transmitted to a remote server over a network protocol such as HTTP or FTP. This type of stream would send the contents of a byte array, one byte at a time, through the stream to the destination, until the entire array has been sent.
