try this

List<JComponent> comboOptionsList=new ArrayList<JComponent>();

its not a good way.... but i think it might work

extend your DateComboBox from JComboBox . than add it...

@Swastik Dey:
thanks for the reply...

just one more query...if i declare the arraylist to be of type <JComponent> then when i execute the following statement

   
String s=comboOptionsList.get(0).getSelectedItem().toString();
 

will i be able to get the string value that the user had entered in the jcombobox(age,name) or datecombobox(dob)??

Probably no you first need it to typecast it to appropriate type

for e.g.

 
if(comboOptionsList.get(0) instanceof JComboBox){
   JComboBox cb=(JComboBox)comboOptionsList.get(0);
   String s=cb.getSelectedItem().toString();
}
else if(comboOptionsList.get(0) instanceof  DateComboBox){
  DateComboBox db=(DateComboBox)comboOptionsList.get(0);
   String s=db.getSelectedItem().toString();
}

Is this a com.jidesoft.combobox.DateComboBox?

The problem is that this and jaxax.swing.JComboBox are in a different inheritance hierarchy - so JComponent is the lowest class they both inherit from.

But, com.jidesoft.combobox.ListComboBox looks like it acts like a simple JComboBox. And both ListComboBox and DateComboBox inherit from com.jidesoft.combobox.AbstractComboBox, which contains the getSelectedItem() method.

So you should be able to do this:

List<AbstractComboBox> comboOptionsList=new ArrayList<AbstractComboBox>();     
ListComboBox age=new ListComboBox();  
ListComboBox name=new ListComboBox();  
DateComboBox dob = new DateComboBox(new DefaultDateModel()) ; 
comboOptionsList.add(age);
comboOptionsList.add(name);
comboOptionsList.add(dob);

...

String s=comboOptionsList.get(0).getSelectedItem().toString();
