Java menu item enabling within event listener

Question

Hello im trying to enable my JMenuItem from within an event listener but it seems to be out of scope. im new to java so how would i properly go about this. the said event listener will change to a new view and enable the disabled menu items.

    //Create and add MenuItems
    JMenuItem fileItem0 = new JMenuItem("Load");
    collMenu.add(fileItem0);

    JMenuItem fileItem1 = new JMenuItem("Add");
    fileItem1.setEnabled(false);
    collMenu.add(fileItem1);

    JMenuItem fileItem2 = new JMenuItem("Delete");
    fileItem2.setEnabled(false);
    collMenu.add(fileItem2);

    //Add Menu bar to frame
    menubar.add(collMenu);

    //Menu Item Functions
    fileItem0.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent actionEvent) {
            JOptionPane.showMessageDialog(null,"You selected: Load.");
            //Enable fileitem1 & 2 here ?? 
        }
    });

I hope this small example will help you clear your doubts...

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class MenuExample extends JFrame {
    JMenuBar menuBar = new JMenuBar();
    JMenu menu = new JMenu("File");
    JMenu menu1 = new JMenu("Edit");
    JMenuItem item1 = new JMenuItem("New");
    JMenuItem item2 = new JMenuItem("Open");

    public MenuExample() {
        setJMenuBar(menuBar);
        setVisible(true);
        setSize(400, 200);
        menuBar.add(menu);
        menuBar.add(menu1);
        menu.add(item1);
        menu.add(item2);
        item1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                JFileChooser chooser = new JFileChooser();
                chooser.showOpenDialog(null);

            }

        });
        item2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                JFileChooser chooser = new JFileChooser();
                chooser.showOpenDialog(null);

            }

        });

    }

    public static void main(String[] args) {
        MenuExample ex = new MenuExample();
    }

}
