Easy way to write contents of a Java InputStream to an OutputStream

Question

I was surprised to find today that I couldn\'t track down any simple way to write the contents of an InputStream to an OutputStream in Java. Obviou

Answer 1

Here comes how I'm doing with simplest for loop.

private void copy(final InputStream in, final OutputStream out)
    throws IOException {
    final byte[] b = new byte[8192];
    for (int r; (r = in.read(b)) != -1;) {
        out.write(b, 0, r);
    }
}
