Please someone give me some sample code to add numbers in jcombobox. This is
my code:
  void cmbCalendar_actionPerformed(ActionEvent e) {
   String s =  (String) cmbYear.getSelectedItem();
   if (s.equals("Gregorian"))
   {
     for (int x = 1583; x < 2501; x++)
     {
       cmbYear.addItem((String) (x));
     ...............
The above line is erroring out. Can someone tell me how to correct this with
a code sample?
thanks.

String s =  (String) cmbYear.getSelectedItem(); is really String s =
(String) cmbCalendar.getSelectedItem();

Why add stuff as strings, when you really want to be dealing with numbers?

cmbYear.addItem( new Integer(x) );
