            byteArrayInputStream = new ByteArrayInputStream(buffer);

             * Read every number inside the buffer using the
             * read() method, which returns -1 if the end of
             * the buffer is reached.
             */
            while ((num = byteArrayInputStream.read()) != -1)
            {
                System.out.print(num + " ");
            }
        }
        finally
        {
            if (byteArrayInputStream != null)
            {
                /*
                 * Closing a ByteArrayInputStream has no
                 * effect. The methods in this class can be
                 * called after the stream has been closed
                 * without generating an IOException.
                 */
                byteArrayInputStream.close();
            }
        }

    }
}
Output
All the elements in the buffer:
0 1 2 3 4
