copied!<p>An <code>OutputStream</code> is one where you write data to. If some module exposes an <code>OutputStream</code>, the expectation is that there is something reading at the other end.</p> <p>Something that exposes an <code>InputStream</code>, on the other hand, is indicating that you will need to listen to this stream, and there will be data that you can read. </p> <p>So it is possible to connect an <code>InputStream</code> to an <code>OutputStream</code></p> <p><code>InputStream----read---> intermediateBytes[n] ----write----> OutputStream</code></p> <p>As someone metioned, this is what the <code>copy()</code> method from <a href="http://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/IOUtils.html" rel="noreferrer">IOUtils</a> lets you do. It does not make sense to go the other way... hopefully this makes some sense</p> <p><strong>UPDATE:</strong></p> <p>Of course the more I think of this, the more I can see how this actually would be a requirement. I know some of the comments mentioned <code>Piped</code> input/ouput streams, but there is another possibility.</p> <p>If the output stream that is exposed is a <code>ByteArrayOutputStream</code>, then you can always get the full contents by calling the <code>toByteArray()</code> method. Then you can create an input stream wrapper by using the <code>ByteArrayInputStream</code> sub-class. These two are pseudo-streams, they both basically just wrap an array of bytes. Using the streams this way, therefore, is technically possible, but to me it is still very strange...</p>
