how do I fill a Jlist with an ArrayList from a JFrame with a different class?

import Empi.Menu;
import java.awt.Color;
import java.util.ArrayList;
import javafx.scene.control.ComboBox;
import javax.swing.DefaultListModel;
import javax.swing.*;
public class Lista extends javax.swing.JFrame {

    private Menu frame;
    public Lista(Menu frame){
        this.frame=frame;
    }

    public Lista() {
        initComponents();
        this.setLocationRelativeTo(null);
        this.setSize(500,500);
        this.setBackground(Color.yellow);
       ????????????
