defining 'reference' to an object
<p>When an object is created, a reference is returned, and not the object.</p>

<p>What does this mean?</p>

<pre><code>object a = new object();
</code></pre>

<p>Here <code>a</code> holds the reference.</p>

<p>It would be helpful if someone explains the creation of the object, creation of references.</p>
