Body
<pre><code>import java.text.DecimalFormat; public class Asdf { public static void main(String[] args) { DecimalFormat format = new DecimalFormat(); format.setDecimalSeparatorAlwaysShown(false); Double asdf = 2.0; Double asdf2 = 2.11; Double asdf3 = 2000.11; System.out.println( format.format(asdf) ); System.out.println( format.format(asdf2) ); System.out.println( format.format(asdf3) ); } } </code></pre> prints: <pre><code>2 2.11 2,000.11 </code></pre> Using <pre><code>DecimalFormat format=new DecimalFormat("#.#"); //not okay!!! </code></pre> is not right as it messes with 10^3, 10^6, etc. separators. 2000.11 would be displayed as "2000.11" instead of "2,000.11" This is of course if you want to display numbers properly formatted, not just using improper toString(). Also note, that formatting may different based on users Locale and DecimalFormat should be initialized accordingly using a factory method with user's Locale as an argument: <pre><code>NumberFormat f = NumberFormat.getInstance(loc); if (f instanceof DecimalFormat) { ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true); } </code></pre> <a href="http://download.oracle.com/javase/1.5.0/docs/api/java/text/DecimalFormat.html">http://download.oracle.com/javase/1.5.0/docs/api/java/text/DecimalFormat.html</a> UPDATE This formatting string works fine also without calling the extra method: <pre><code> DecimalFormat format=new DecimalFormat("#,###.#"); //format.setDecimalSeparatorAlwaysShown(false); </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.
