Nice tutorial. Although I would like to point out that this is not the only way to do it,but an efficient way nonetheless.

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!! :)

yey!! this is what i'm lloking for!!! tnx tnx tnx!!!

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.

thank you Mr.javaPF
i like the lesson

I have another code

Code :

---

import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuItem;
import javax.swing.JMenuBar;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
 
public class menuDemo extends JFrame implements ActionListener{
 
	 public static final int width = 300;
	 public static final int height = 300;
 
	 public static void main(String[] args)
	  {
	  menuDemo gui = new menuDemo();
	  gui.setVisible(true);
	 }
 
	 public menuDemo()
	 {
	  super("Menu bar :");
	  setSize( width, height );
	  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
 
	  JMenu fileMenu = new JMenu("File");
 
	  JMenuItem open = new JMenuItem("Open");
	  open.addActionListener(this);
	  fileMenu.add(open);
 
	  JMenuItem save = new JMenuItem("Save");
	  save.addActionListener(this);
	  fileMenu.add(save);
 
	  JMenuItem quit = new JMenuItem("Quit");
	  quit.addActionListener(this);
	  fileMenu.add(quit);
 
	  JMenuBar bar = new JMenuBar();
	  bar.add(fileMenu);
	  setJMenuBar(bar);
 
	   }
 
	 public void actionPerformed(ActionEvent e) {
 
 
	        String command = e.getActionCommand();
 
	        if (command.equals("Quit")) {
	            System.exit(0);
	        } else if (command.equals("Open")) {
	            System.out.println("Open menu item clicked");
	        } else if (command.equals("Save")) {
	            System.out.println("Save menu item clicked");
	        }
	    }
