Menuji

standardnih AWT menujev v apletih ne moremo uporabljati, lahko pa jih uporabljamo v aplikacijah, kot kaže naslednji zgled;

import java.awt.*;
import java.awt.event.*;

public class MenuNew extends Frame {
  String[] flavors = { "Chocolate", "Strawberry",
    "Vanilla Fudge Swirl", "Mint Chip", 
    "Mocha Almond Fudge", "Rum Raisin", 
    "Praline Cream", "Mud Pie" };
  TextField t = new TextField("No flavor", 30);
  MenuBar mb1 = new MenuBar();
  Menu f = new Menu("File");
  Menu m = new Menu("Flavors");
  Menu s = new Menu("Safety");
  // Alternative approach:
  CheckboxMenuItem[] safety = {
    new CheckboxMenuItem("Guard"),
    new CheckboxMenuItem("Hide")
  };
  MenuItem[] file = {
    // No menu shortcut:
    new MenuItem("Open"),
    // Adding a menu shortcut is very simple:
    new MenuItem("Exit", 
      new MenuShortcut(KeyEvent.VK_E))
  };
  // A second menu bar to swap to:
  MenuBar mb2 = new MenuBar();
  Menu fooBar = new Menu("fooBar");
  MenuItem[] other = {
    new MenuItem("Foo"),
    new MenuItem("Bar"),
    new MenuItem("Baz"),
  };
  // Initialization code:
  {
    ML ml = new ML();
    CMIL cmil = new CMIL();
    safety[0].setActionCommand("Guard");
    safety[0].addItemListener(cmil);
    safety[1].setActionCommand("Hide");
    safety[1].addItemListener(cmil);
    file[0].setActionCommand("Open");
    file[0].addActionListener(ml);
    file[1].setActionCommand("Exit");
    file[1].addActionListener(ml);
    other[0].addActionListener(new FooL());
    other[1].addActionListener(new BarL());
    other[2].addActionListener(new BazL());
  }
