MenuTest.java - AWT Menu Test Program

This section provides a tutorial example on how to use the java.awt.Menu class to create multiple menus and how to add them to the menu bar. Sub menus and menu items added to a menu will be listed vertically when the menu is selected.

Here is an example program I wrote to test the java.awt.Menu class:

import java.awt.Frame; 
import java.awt.MenuBar; 
import java.awt.Menu; 
import java.awt.MenuItem; 
public class MenuTest {
   Frame myFrame = null;
   public static void main(String[] a) {
      (new MenuTest()).test();
   }
   private void test() {
      myFrame = new Frame("Menu Test");
      myFrame.setBounds(50,50,250,150);
      MenuBar myMenuBar = new MenuBar();
      Menu myMenu = getFileMenu();
      myMenuBar.add(myMenu);
      myMenu = getColorMenu();
      myMenuBar.add(myMenu);

      myFrame.setMenuBar(myMenuBar);
      myFrame.setVisible(true);
   }
   private Menu getFileMenu() {
      Menu myMenu = new Menu("File");
      Menu mySubMenu = getOpenMenu();
      myMenu.add(mySubMenu);
      MenuItem myItem = new MenuItem("Close");
      myMenu.add(myItem);
      myMenu.addSeparator();
      myItem = new MenuItem("Exit");
      myMenu.add(myItem);
      return myMenu;
   }
   private Menu getColorMenu() {
      Menu myMenu = new Menu("Color");
      MenuItem myItem = new MenuItem("Red");
      myMenu.add(myItem);
      myItem = new MenuItem("Green");
      myMenu.add(myItem);
      myItem = new MenuItem("Blue");
      myMenu.add(myItem);
      return myMenu;
   }
   private Menu getOpenMenu() {
      Menu myMenu = new Menu("Open");
      MenuItem myItem = new MenuItem("Java");
      myMenu.add(myItem);
      myItem = new MenuItem("HTML");
      myMenu.add(myItem);
      myItem = new MenuItem("GIF");
      myMenu.add(myItem);
      return myMenu;
   }
}

If you run this example, you will see the frame window shows up with the menu bar like this:
