    <p>No you can't change the size of an array once created. You either have to allocate it bigger than you think you'll need or accept the overhead of having to reallocate it needs to grow in size. When it does you'll have to allocate a new one and copy the data from the old to the new:</p> <pre><code>int oldItems[] = new int[10]; for (int i=0; i&lt;10; i++) { oldItems[i] = i+10; } int newItems[] = new int[20]; System.arraycopy(oldItems, 0, newItems, 0, 10); oldItems = newItems; </code></pre> <p>If you find yourself in this situation, I'd highly recommend using the Java Collections instead. In particular <a href="http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html" rel="noreferrer"><code>ArrayList</code></a> essentially wraps an array and takes care of the logic for growing the array as required:</p> <pre><code>List&lt;xClass&gt; mysclass = new ArrayList&lt;xClass&gt;(); myclass.add(new xClass()); myclass.add(new xClass()); </code></pre> <p>Generally an <code>ArrayList</code> is a preferable solution to an array anyway for several reasons. For one thing, arrays are mutable. If you have a class that does this:</p> <pre><code>class Myclass { private int items[]; public int[] getItems() { return items; } } </code></pre> <p>you've created a problem as a caller can change your private data member, which leads to all sorts of defensive copying. Compare this to the List version:</p> <pre><code>class Myclass { private List&lt;Integer&gt; items; public List&lt;Integer&gt; getItems() { return Collections.unmodifiableList(items); } } </code></pre>

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.
