How update or modified an Object within an jComboBox.setEditable(true)

Question

Hello,
I would like to modified the name of an object which is displayed within a jComboBox which is setEditable(true). As we can do within a jTable with the setValueAt method.
Here is a sample of my code:
public class MyFrame extends JFrame {
Object[] listeVoiture = new Object[2];
listeVoiture [0] = new Voiture("Clio", "458 AVB 38");
listeVoiture [1] = new Voiture("Megane", "4567 ZE 69");
MyComboBoxModel voitureComboBoxModel = new MyComboBoxModel(listeVoiture);
JComboBox jComboBoxListeVoiture = new JComboBox(voitureComboBoxModel);
jComboBoxListeVoiture.setEditable(true);
public class Voiture {
Private String modele;
Private String numPlaque;
public Voiture(String mod, String plaq){
modele= mod;
numplaq=plaq;
public String toString(){
return modele;
public void setModele(String mod){
modele=mod;
public class MyComboBoxModel extends DefaultComboBoxModel {
public MyComboBoxModel(Object[] items) {
super(items);
public void setSelectedItem(Object anObject) {
Voiture voit = (Voiture)this.getSelectedItem();
voit .setModele(anObject.toString());
super.setSelectedItem(app);
Thank you for your advises, Romain.

You can do a remove/insert... (why doesn't DefaultComboBoxModel have a set method?)
Kind regards,
