Java
//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.
