    <p>As per the <a href="http://java.sun.com/javase/6/docs/api/java/util/Vector.html" rel="nofollow noreferrer">API docs</a>, <code>Vector</code> just implements <code>List</code>, so I don't forsee problems. Maybe your confusion was caused because you declared <code>Vector</code> according the old Java 1.0 style:</p> <pre><code>Vector vector = new Vector(); </code></pre> <p>instead of the declaring it aginst the interface (which is considered good practice):</p> <pre><code>List list = new Vector(); </code></pre> <p>You can thus just make use of <a href="http://java.sun.com/javase/6/docs/api/java/util/Collections.html#sort%28java.util.List%29" rel="nofollow noreferrer"><code>Collections#sort()</code></a> to sort a collection, <a href="http://java.sun.com/javase/6/docs/api/java/lang/Comparable.html" rel="nofollow noreferrer"><code>Comparable</code></a> to define the default ordering behaviour and/or <a href="http://java.sun.com/javase/6/docs/api/java/util/Comparator.html" rel="nofollow noreferrer"><code>Comparator</code></a> to define an external controllable ordering behaviour.</p> <p>Here's a <a href="http://java.sun.com/docs/books/tutorial/collections/interfaces/order.html" rel="nofollow noreferrer">Sun tutorial</a> about ordering objects.</p> <p>Here's another <a href="https://stackoverflow.com/questions/1814095/sorting-an-arraylist-of-contacts/1814112#1814112">SO answer</a> with complete code examples.</p> <p>That said, why are you still sticking to the <em>legacy</em> <code>Vector</code> class? If you can, just replace by the improved <a href="http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html" rel="nofollow noreferrer"><code>ArrayList</code></a> which was been designed as replacement of <code>Vector</code> more than a decade ago.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
