what information would you like exactly?

yopu can use a renderer to hadle how your object is displayed

You can cast (as shgown above), and use instanceof to check the type of the value

eg.

Object selected = combo.getSelectedItem();
if (selected instanceof MyBean)
{
   MyBean bean = (MyBean) selected;
   String property = bean.getProperty();
  // ...
}

where MyBean is obne of your classes that you are stoing in the combo


you'll find lots of goo info on usoing combos here:
