How to create a Vertical menu bar in Java?

Let us create a MenuBar −

JMenuBar menuBar = new JMenuBar();

Now, set its layout to create a Vertical Menu Bar with GridLayout −

menuBar.setLayout(new GridLayout(0,1));

The following is an example to create a Vertical menu bar in Java −

Example

package my; import java.awt.GridLayout; import java.awt.event.KeyEvent; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; public class SwingDemo {    public static void main(final String args[]) {       JFrame frame = new JFrame("MenuBar Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JMenuBar menuBar = new JMenuBar();       menuBar.setLayout(new GridLayout(0,1));       JMenu fileMenu = new JMenu("File");       fileMenu.setMnemonic(KeyEvent.VK_F);       menuBar.add(fileMenu);       JMenuItem menuItem1 = new JMenuItem("New", KeyEvent.VK_N);       fileMenu.add(menuItem1);       JMenuItem menuItem2 = new JMenuItem("Open File", KeyEvent.VK_O);       fileMenu.add(menuItem2);       JMenu editMenu = new JMenu("Edit");       editMenu.setMnemonic(KeyEvent.VK_E);       menuBar.add(editMenu);       JMenuItem menuItem3 = new JMenuItem("Cut", KeyEvent.VK_C);       editMenu.add(menuItem3);       JMenu sourceMenu = new JMenu("Source");       sourceMenu.setMnemonic(KeyEvent.VK_S);       menuBar.add(sourceMenu);       JMenu refactorMenu = new JMenu("Refactor");       refactorMenu.setMnemonic(KeyEvent.VK_R);       menuBar.add(refactorMenu);       JMenu navigateMenu = new JMenu("Navigate");       navigateMenu.setMnemonic(KeyEvent.VK_A);       menuBar.add(navigateMenu);       menuBar.revalidate();       frame.setJMenuBar(menuBar);       frame.setSize(550, 350);       frame.setVisible(true);    } }

This will produce the following output −
