Dynamic array, which can also be saved to file
<p>In my Android application, I need to make a list of favorite items. Each of these items consists of 3 key/value pairs. I want a dynamic array capable of:</p>

<ul>
<li>Insertion at end only</li>
<li>Sortable</li>
<li>Deletion at any point</li>
<li>Can be saved to File</li>
</ul>

<p>Any suggestions?</p>
