Set<Integer> inside Map
<p>I have a question. First, I declared a map:</p>

<pre><code>Map&lt;TwoIntClass, Set&lt;Integer&gt;&gt; m = new HashMap&lt;TwoIntClass, Set&lt;Integer&gt;&gt;();
</code></pre>

<p>Now, I want to put stuff inside this map, something like</p>

<pre><code>int num = 7;
m.put(new TwoIntClass(5, 3), ?? how to put num inside Set ??);
</code></pre>

<p>My question is, how do I put variable num inside Set.
Thanks.</p>
