Java Menu setout problems.

Question

Dear Everyone,
I am currently experiencing some problems with organising a User Interface that uses menu items. This code creates a File menu and a New menu that sit side by side (with New to the right of File). I am trying to design a menu that has only File visible, with New showing below File only when File is pressed. Can anybody please suggest modifications that will make this possible. Thanks.
Regards

class GUI extends JFrame
GUI()
Toolkit tk = Toolkit.getDefaultToolkit(); //intialize the toolkit.
Dimension sSize = tk.getScreenSize(); //determine screen size.
Container c = getContentPane();
c.setLayout(new FlowLayout());
JMenuBar menuBar = new JMenuBar(); //Creates Menubar object called menuBar.
setJMenuBar(menuBar);
JMenu FMenu = new JMenu("File"); //File Menu object instantiated.
FMenu.setMnemonic(KeyEvent.VK_F); //Key that activates File menu...F.
menuBar.add(FMenu); //File Menu added to menuBar object.
JMenuItem NewItem = new JMenuItem("New"); //Creates New sub-menu object.
NewItem.setMnemonic(KeyEvent.VK_N); //Key that activates New sub-
//menu....N.
menuBar.add(NewItem);
setLocation(sSize.width/4,sSize.height/4);
setSize(sSize.width/2,sSize.height/4);
setTitle("Java QuickLaunch Toolbar");
setVisible(true);
}

Change
menuBar.add(NewItem);to:
FMenu.add(NewItem);You need to add to the menu, not to the menubar, that's why it wasn't appearing in the correct place.
