java.lang.ClassCastException

[javaken]

Hey,

I have following exception : java.lang.ClassCastException

I've read a file, and put the values in objects of a class.
I've put the objects in a combobox. Now I have a list with items .... that I can select but ....
I want to use a selected item, en put it in a string ...

How to do this??? How to cast???

Thanks!!!

Can you post the relevant code ... (get the line number from the exeception)

You cannot cast from Objects that are not in the same hierachy - eg :

// will not work - 
Object o = new Integer("1");
String s = (String)o;

// Will work
Object o = new String("1");
String s = (String)o;

String s = (String)thingsComboBox.getSelectedItem(); gives an error

In class things I have:
ID (== int) + thing (==string) = one object

object is sitting in my combobox.

How can I get the contents of thing1 when item 1 in my comboBox is selected. You to put it in a string???

Thanks ...

Quick hack is :

String s = "" +thingsComboBox.getSelectedItem();
