How to copy the content of an input stream to an output stream
/** * Copy the content of the input stream into the output stream, using a temporary * byte array buffer whose size is defined by {@link #IO_BUFFER_SIZE}. * * @param in The input stream to copy from. * @param out The output stream to copy to. * * @throws IOException If any error occurs during the copy. */ private static final int IO_BUFFER_SIZE = 4 * 1024; private static void copy(InputStream in, OutputStream out) throws IOException { byte[] b = new byte[IO_BUFFER_SIZE]; int read; while ((read = in.read(b)) != -1) { out.write(b, 0, read); } }
