java - add selected Item from Jcombobox to Jlist

Question

i have created a Jcombobox and i have populated it from data base, i have a JList and i want every item i select in the combobox to be added on the JList. i'm new to java and i tried to solve the problem with this code but it's not working :

 private void addelementActionPerformed(java.awt.event.ActionEvent evt) {                                           

   DefaultListModel liss = new DefaultListModel();

   Object  s = empcombo_s.getSelectedItem().toString();


   for(int i =0; i<=1;i++) { 
    liss.add(i, s);
}

   stagelist.setModel(liss);
} 

Answer 1

now this code is working properly :

  DefaultListModel liss = new DefaultListModel();
private void addelementActionPerformed(java.awt.event.ActionEvent evt) {                                           

   String  s = empcombo_s.getSelectedItem().toString();
  liss.addElement(s);
   stagelist.setModel(liss);
}
