remove element from vector of vectors
<p>I try to remove an element from vector of verctors in Java, and set this vector to the correct location.</p>

<p>So I try this, and of course it didn't work because line (2) return Integer:</p>

<p>Definition: </p>

<pre><code>Vector&lt;Vector&lt;Integer&gt;&gt; current_domain;

Vector&lt;Integer&gt; t = current_domain.get(k).remove(0);
current_domain.set(k, t);
</code></pre>
