How to prepare list which contains list objects?
<p>I am fetching the records from database and those value like this</p>

<pre><code>1,"a"
1,"b"
2,"c"
3,"d"
3,"e"
4,"f"
</code></pre>

<p>Here I got result into ResultSet now I want to prepare list like</p>

<pre><code>[[a,b],[c],[d.e],[f]]
</code></pre>

<p>Any one can help me how to solve this, I tried with the list and map concept but I am getting last list object only.
Thanks</p>
