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

As WMR mentioned, org.apache.commons.io.IOUtils from Apache has a method called copy(InputStream,OutputStream) which does exactly what you’re looking for.

So, you have:

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

…in your code.

Is there a reason you’re avoiding IOUtils?
