vector.push_back equivalent in Java
<p>In <code>C++</code>, I don't have to know the size of how much content I'm going to stuff into a int vector while declaring it, i.e.</p>

<pre><code>vector&lt;int&gt; x;
x.push_back(1);
...
...
...
x.push_back(10);
</code></pre>

<p>What would be an equivalent data structure for doing the same in <code>Java</code>?</p>
