What Is Wrong with the Following Code? Class ExitListener Implements

What is wrong with the following code? class ExitListener implements ActionListener
{
Public void actionPerformed(ActionEvent event)
{
System.exit(0) ;
}
}
ActionListener exitListener = new ExitListener() ;
JMenu exitMenu = new JMenu("Exit") ;
ExitMenu.addActionListener(exitListener) ;
JMenuBar menuBar = new JMenuBar() ;
MenuBar.add(exitMenu) ;

A) The ExitListener class is not public
B) You cannot attach a listener to a menu, only to a menu item
C) You cannot add a menu to the menu bar, only a menu item
D) You need to use a menu listener, not an action listener
