An Int argument in the ArrayList, what is it?
<p>What is the difference between this:</p>

<pre><code>ArrayList&lt;String&gt; test = new ArrayList&lt;String&gt;();
</code></pre>

<p>and this:</p>

<pre><code>ArrayList&lt;String&gt; test = new ArrayList&lt;String&gt;(3);
</code></pre>

<p>I just tested the Array and I really see no difference.. I always see people using a number there, what is it for ?</p>
