Thread: Java program to Add a JMenu toolbar to a Java Swing application

With this code you can add a JMenu toolbar to your Java Swing applications.

import java.awt.event.*;

public class JMenuExample extends JFrame implements ActionListener {
 
    public static void main(String[] s) {
        new JMenuExample();
    }
 
    public JMenuExample() {
 
        super("JMenu Example");
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
 
        // Name the JMenu & Add Items
        JMenu menu = new JMenu("File");
        menu.add(makeMenuItem("Open"));
        menu.add(makeMenuItem("Save"));
        menu.add(makeMenuItem("Quit"));
 
        // Add JMenu bar
        JMenuBar menuBar = new JMenuBar();
        menuBar.add(menu);
        setJMenuBar(menuBar);
        setSize(300, 300);
        setLocation(200, 200);
        setVisible(true);
    }
 
    public void actionPerformed(ActionEvent e) {
 
        // Menu item actions
        String command = e.getActionCommand();
 
        if (command.equals("Quit")) {
            System.exit(0);
        } else if (command.equals("Open")) {
            // Open menu item action
            System.out.println("Open menu item clicked");
        } else if (command.equals("Save")) {
            // Save menu item action
            System.out.println("Save menu item clicked");
        }
    }
 
    private JMenuItem makeMenuItem(String name) {
        JMenuItem m = new JMenuItem(name);
        m.addActionListener(this);
        return m;
    }
}

Thanks Fendaril but I would also like to thank John for this code.

You are correct, this is not the only way to do it. If you would like to post some alternative solutions that would be great!!

Menu mnemonics can be used to open a menu by typing a single character associated with a menu along with an operating system defined key for this action. e.g. fileMenu.setMnemonic('F');

Menu item mnemonics are used to select a menu item when its menu is already open.

Accelerator key combinations are used to directly invoke a menu item without opening the menu, for example the common CTRL-C (Copy) execute the copy menu action. e.g. openItem.setAccelerator(KeyStroke.getKeyStroke("co ntrol O")); // control O for open, control C for copy.
