This is all I have regarding the question

import java.awt.event.*;

import javax.swing.*;

public class Quiz8_GUI

{

private JFrame frame;   

/**

* Create an Quiz8_GUI show it on screen.

*/

public Quiz8_GUI()

{

makeFrame();

}

// ---- swing stuff to build the frame and all its components ----

/**

* Create the Swing frame and its content.

*/

private void makeFrame()

{

frame = new JFrame("Quiz8_GUI");

makeMenuBar(frame);

Container contentPane = frame.getContentPane();

//set the Container to flow layout

//Your code goes here:

// create a button bOpen with "Open" shown on it, and add to the Panel

//add event processing to bOpen button, and and call openFile()

//when event is triggered

//Your code goes here:

//create a button bExit with "Exit" shown on it, and add to the Panel

//add event processing to bExit button, and  

//exit the system in exit button event.

//Your code goes here:

frame.pack();

frame.setVisible(true);

}

private void makeMenuBar(JFrame frame){   

JMenuBar menubar = new JMenuBar();

frame.setJMenuBar(menubar);

JMenu menu;

menu = new JMenu("File");

menubar.add(menu);  

//create the Open menu item called oItem and add it to File menu,

//add event listener and event processing to oItem, and call openFile()

//when event is triggered

//Your code goes here:

//create the Open menu item called eItem and add it to File menu,

//add event listener and event processing to eItem, and quit the program

//when event is triggered

//Your code goes here:

}

private void openFile(){

//For demonstration purpose, simply print out a word,
