    <p>The best way to solve this problem is to use the Visitor Pattern.</p> <p>For example :</p> <pre><code>import java.awt.EventQueue; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; import javax.swing.WindowConstants; public class Main { public static class JavaMethod implements Iterable&lt;Parameter&gt; { private List&lt;Parameter&gt; parameters; public JavaMethod() { this.parameters = new ArrayList&lt;&gt;(); // This is an example this.parameters.add(new IntegerParameter()); this.parameters.add(new StringParameter()); } @Override public Iterator&lt;Parameter&gt; iterator() { return this.parameters.iterator(); } } public static interface Parameter { public void accept(ParameterVisitor visitor); } public static class IntegerParameter implements Parameter { public int value = 10; @Override public void accept(final ParameterVisitor visitor) { visitor.visit(this); } } public static class StringParameter implements Parameter { public String value = "Hello"; @Override public void accept(final ParameterVisitor visitor) { visitor.visit(this); } } public static interface ParameterVisitor { void visit(StringParameter stringParameter); void visit(IntegerParameter integerParameter); } public static class ParameterSwingVisitor implements ParameterVisitor { private final JComponent container; public ParameterSwingVisitor(final JComponent container) { this.container = container; } @Override public void visit(final StringParameter stringParameter) { this.container.add(new JTextField(stringParameter.value)); } @Override public void visit(final IntegerParameter integerParameter) { // This could be a custom component to pick numbers this.container.add(new JLabel(String .valueOf(integerParameter.value))); } } public static void main(final String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { JPanel myPanel = new JPanel(); // view JavaMethod myMethod = new JavaMethod(); // model final ParameterVisitor visitor = new ParameterSwingVisitor( myPanel); for (final Parameter picked : myMethod) { picked.accept(visitor); // This will add the appropriate // swing // component } JFrame myFrame = new JFrame("Visitor pattern"); myFrame.setContentPane(myPanel); myFrame.setVisible(true); myFrame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE); myFrame.setSize(500, 500); } }); } } </code></pre> <p>More information about this pattern <a href="http://en.wikipedia.org/wiki/Visitor_pattern" rel="nofollow">here</a>.</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.
