Combo question

Question

Hello
How can i GET the elements from a combo box, and then sorting them? i have a combobox, and when i press a button, i wanna sort the values from that combobox, and after that display the sorted values.
to sort, is not a problem,
Arrays.sort(...,Collator.getInstance())but how can i get into a string those elements?
i tried with
if(e.getActionCommand()=="menuSort"){
               try {
                    Component s3Combo[]=combo.getComponents();
                    //System.out.println(s3Combo.toString()+"\n");
                    Arrays.sort(s3Combo,Collator.getInstance());
                    combo.repaint();
               } catch (Exception ex) {
          }this isn't sorting the values. Why?
Thanks

It's too bad DefaultComboBoxModel does not implement java.util.Collection, as this would be really easy then...
Roll your own (untested code):
DefaultComboBoxModel model = createYourModel();
JComboBox combo = new JComboBox(model);
public void sortComboChoices() {
   int count = model.getSize();
   ArrayList list = new ArrayList(count);
   for (int i=0; i<count; i++) {
      list.add(model.getElementAt(i));
   Collections.sort(list);
   model.removeAllElements();
   for (int i=0; i<count; i++) {
      model.addElement(list.get(i));
