I have a List and a Choice on an applet and I want a TextField below them to
display the selected text of each one. Everything's good until runtime when
I actually select one, I get errors (below). There is an ItemListener on
both the List and the Choice. First, here is my itemStateChanged method:
public void itemStateChanged(ItemEvent ie)
{
Choice selBrgd = (Choice)ie.getItemSelectable();
List selType = (List)ie.getItemSelectable();
tfResult.setText("A " + selBrgd.getSelectedItem() + " " +
selType.getSelectedItem());
}
And here are the errors:
java.lang.ClassCastException
at JavaTest.Chapter13.CardChoice.itemStateChanged(CardChoice.java:51)
at java.awt.Choice.processItemEvent(Unknown Source)
at java.awt.Choice.processEvent(Unknown Source)

Thanks,
