    private JList<String> langages;
  
    public JListExample() 
    {
        //create the model and add elements
        DefaultListModel<String> model = new DefaultListModel<>();
        model.addElement("Java");
        model.addElement("JEE");

        langages = new JList<>(model);
        add(langages);
         
        this.setTitle("JList Example");  
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     
        this.setSize(200,200);
        this.setLocationRelativeTo(null);
        this.setVisible(true);
