What is the easy way to write to OutputStream from Java to InputStream?

Is there an easy way to write OutputStream with InputStream? It's not hard to write to the byte buffer code, but I think I'm missing an easier way...

If InputStream has in and OutputStream has out

byte[] buffer = new byte[1024];
int len = in.read(buffer);
while (len != -1) {
    out.write(buffer, 0, len);
    len = in.read(buffer);
}

Is there any easier code than this?

The Apache Common library has a class called IOUtils. You can do it easily by using the method called copy in this class.

InputStream in;
OutputStream out;
IOUtils.copy(in,out);
in.close();
out.close();

You can do it like this.
