Code Completion 11.103 Add listeners to menu

Add the menu items shown below.

Add a listener to the second menu item that turns the content pane yellow.

Here is a sample program output:

Complete the following code:

import javax.swing.JFrame;
import javax.swing.JMenuBar;
import javax.swing.JMenu;
import javax.swing.JMenuItem;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class MenuFrame extends JFrame
{
   private JMenuBar menuBar;
   private JMenu fileMenu;
   private JMenu editMenu;
   private JMenu aboutMenu;

   public MenuFrame()
   {
      menuBar = new JMenuBar();
      fileMenu = new JMenu("File");
      fileMenu.setMnemonic('F');
      editMenu = new JMenu("Edit");
      aboutMenu = new JMenu("About");

      // TODO: Add menu items

      // TODO: Add listener to second menu item

      setJMenuBar(menuBar);
      menuBar.add(fileMenu);
      menuBar.add(editMenu);
      menuBar.add(aboutMenu);
   }
}

The following class is used to check your work:

import javax.swing.JFrame;

public class MenuFrameViewer
{
   public static void main(String[] args)
   {
      MenuFrame frame = new MenuFrame();
      frame.setBounds(50,50,400,200);
      frame.setTitle("MenuFrameViewer");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setVisible(true);
   }
}
