Do IF statements conflict each other if they cover the same thing?
<p>If you have two <code>if</code> statements for:</p>

<pre><code>int n = -1;

if (n &lt; 0)
    return null;

if (n &lt;= 1)
    return "yay";
</code></pre>

<p>Will it return null or yay? Will it run through the code top to bottom and stop at the first <code>if</code> statement, or will the last one be used?</p>
