Java AWT MenuItem & Menu

Java Abstract Window Toolkit (AWT) provides a comprehensive set of classes and methods to create graphical user interfaces. In this article, we will explore the MenuItem and Menu classes, which are essential for building menus in Java applications.

Java AWT MenuItem

MenuItem is a class that represents a simple labeled menu item within a menu. It can be added to a menu using the Menu.add(MenuItem mi) method.

Syntax of Class Declaration MenuItem:

public class MenuItem extends MenuComponent implements Accessible

Methods of the MenuItem Class

List of methods available in MenuItem with description.

Java AWT Menu Class

The Java AWT Menu class represents a pop-up menu component in a graphical user interface (GUI) that can contain a collection of MenuItem objects. It provides a way to create and manage menus in Java AWT applications.

Syntax of Class Declaration of Menu

public class Menu extends MenuItem

Example usage of the MenuItem & Menu

//Java class to implement AWT Menu
// and MenuItem
import java.awt.*;
import java.awt.event.*;

//Driver Class
public class MenuExample {
  
      //Main Method
    public static void main(String[] args) {
        Frame frame = new Frame("Menu Example");
        MenuBar menuBar = new MenuBar();
        frame.setMenuBar(menuBar);

        // Create a "File" menu
        Menu fileMenu = new Menu("File");
        MenuItem openItem = new MenuItem("Open");
        MenuItem saveItem = new MenuItem("Save");
        fileMenu.add(openItem);
        fileMenu.add(saveItem);
        fileMenu.addSeparator();

        // Create an "Exit" menu item with an action listener
        MenuItem exitItem = new MenuItem("Exit");
        exitItem.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
      
          //Added exit as item in MenuItem
        fileMenu.add(exitItem);

        menuBar.add(fileMenu);

        frame.setSize(300, 300);
        frame.setVisible(true);
    }
}

This code creates a simple window with a "File" menu that contains "Open," "Save," and "Exit" options. When you click "Exit," the application exits.

Conclusion

In this article, we explored the very necessary components of Java AWT's MenuItem and Menu classes.

• These classes are material for creating menus in graphical user interfaces.
• We discussed the phrase structure of class declarations,
• Registered the methods with their descriptions.
• Introduced the constructors for some classes.

By combining these classes and their joint methods, you can build interactive and user-friendly menus for your Java applications. The provided code example demonstrated how to make a simpleton fare bar, offer a practical starting point for development of more complex graphical interfaces in Java.
