    <p>Actually, probably the "best" way to initialize the <code>ArrayList</code> is the method you wrote, as it does not need to create a new <code>List</code> in any way:</p> <pre><code>ArrayList&lt;String&gt; list = new ArrayList&lt;String&gt;(); list.add("A"); list.add("B"); list.add("C"); </code></pre> <p>The catch is that there is quite a bit of typing required to refer to that <code>list</code> instance.</p> <p>There are alternatives, such as making an anonymous inner class with an instance initializer (also known as an "double brace initialization"):</p> <pre><code>ArrayList&lt;String&gt; list = new ArrayList&lt;String&gt;() {{ add("A"); add("B"); add("C"); }}; </code></pre> <p>However, I'm not too fond of that method because what you end up with is a subclass of <code>ArrayList</code> which has an instance initializer, and that class is created just to create one object -- that just seems like a little bit overkill to me.</p> <p>What would have been nice was if the <a href="http://mail.openjdk.java.net/pipermail/coin-dev/2009-March/001193.html" rel="noreferrer">Collection Literals proposal</a> for <a href="http://openjdk.java.net/projects/coin" rel="noreferrer">Project Coin</a> was accepted (it was slated to be introduced in Java 7, but it's not likely to be part of Java 8 either.):</p> <pre><code>List&lt;String&gt; list = ["A", "B", "C"]; </code></pre> <p>Unfortunately it won't help you here, as it will initialize an immutable <code>List</code> rather than an <code>ArrayList</code>, and furthermore, it's not available yet, if it ever will be.</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.
