public class Main {
  private String[] elements = { "Monday", "Tueday", "Wednesday" };
  private JList made_list = new JList();

  public Main() {
    made_list.setModel(new DefaultListModel());
    for (String element : elements) {
      ((DefaultListModel) made_list.getModel()).addElement(element);
    }

    JButton removeItemBtn = new JButton("Remove Item");
    removeItemBtn.addActionListener(new ActionListener() {
      @Override

    panel.add(removeItemBtn);

    JOptionPane.showMessageDialog(null, panel);
  }

  private void removeActionPerformed(ActionEvent e) {
    System.out.println("made_list's model: " + made_list.getModel());
    System.out.println("Model from a fresh JList: " + new JList().getModel());
    DefaultListModel model = (DefaultListModel) made_list.getModel();
    if (model.size() > 0) {
      model.remove(0);

    new Main();
