Java AWT Adding MenuBar, Menu to GUI Window

Java AWT Adding MenuBar, Menu to GUI Window:

This code is continuation of this tutorial Java AWT Creating Piano Buttons with Grid Layout.

First of all none of the buttons will work because i haven’t added any event listeners and handlers. Also menu items are not added yet.

public class SimpleAwtGui {

    private static final int button_count = 10;

    // Declare a Frame type variable
    Frame frame;
    MenuBar menuBar;
    Menu fileMenu, optionsMenu, exitMenu;

    // Create an array of Button type Objects
    Button [] button = new Button[button_count];

    public SimpleAwtGui() {
        // Create Frame Object and pass in the Frame Name / title
        frame = new Frame("AWT GUI EXAMPLE");

        // Use for loop to instantiate every button object
        for(int i = 0; i < button_count; ++i){
            button[i] = new Button( "" + i );

        // Create MenuBar Object
        menuBar = new MenuBar();

        // Create Menu objects to add to the MenuBar
        fileMenu = new Menu("File");
        optionsMenu = new Menu("Options");
        exitMenu = new Menu("Exit");

    public static void main(String[] args) {

        // Create an instance of SimpleAwtGui
        SimpleAwtGui window = new SimpleAwtGui();

        // call the showFrame() function to display the window


    // Not necessary but good practice all codes inside this can be written inside main
    public void showFrame() {
        // set the size of the window
        frame.setSize(400, 400);

        // set the layout for the window
        frame.setLayout(new GridLayout());

        // Add all of the buttons to the layout
        for(int i = 0; i < button_count; ++i) {

        // Register window listener event to the frame without implementing WindowListener
                new WindowAdapter() {
                    public void windowClosing(WindowEvent e) {

        // Add Menu to the MenuBar

        // Add MenuBar to the Frame

        // set the frame visible otherwise nothing will be shown
