 @override public void itemstatechanged(itemevent e) {     set<string> countries = regionmap.get(listregion.getselecteditem());     listsubregion.removeall();     for(string country : countries)     {         listsubregion.add(country);     }      selectedregion = listregion.getselecteditem();      listsubregion.validate();     listsubregion.repaint();      repaint(); }
