Menus:

Menus are just like buttons - you will add them and a actionlistener. In actionPerformed, if the source is them, do something. Below is an example

   
//as globals
    private JMenuBar menuBar=new JMenuBar();
    private JMenu fileMenu=new JMenu("File");
    private JMenuItem openMenuItem=new JMenuItem("Open");;
    private JMenuItem saveMenuItem=new JMenuItem("Save");
//in init
		menuBar.add(fileMenu);
        fileMenu.add(openMenuItem);
        fileMenu.add(saveMenuItem);
        openMenuItem.addActionListener(this);
        saveMenuItem.addActionListener(this);
        setJMenuBar(menuBar);
