hi all
the Jlist is populating now after I used default list model
now i have a new problem...I thought of removing elements from
the list when user clicks on it
my code for that is
public void valueChanged(ListSelectionEvent e) {
//        if (e.getValueIsAdjusting() == false) {
        int index=(int)listRole.getSelectedIndex();
        System.out.println(index);
        listModel.removeElementAt(index);
        if (index == listModel.getSize())//removed item in last position
            index--;
        listRole.setSelectedIndex(index);   //otherwise select same index
    }but whenever i click on any item
it is giving array out of bound exception
and item is removed but the next element is duplicated
why is this happening ?
please help me
