Who would like to fond out for a single error in this code (JAVA) with GUI part

Question

Import java.awt.*;

import javax.swing.* ;

class MyWindow extends JFrame {

private JMenuBar barreMenus ;

private JMenu Color, Dimensions ;

private JMenuItem RedColor,GreenColor;

private JMenuItem Height,Larger ;

public MyWindow () {

super("Window with a menu") ;

setSize(300, 200) ;

barreMenus = new JMenuBar() ;

setJMenuBar(barreMenus) ;

Color = new JMenu("Color") ;

barreMenus.add(Color) ;

RedColor = new JMenuItem("RedColor") ;

RedColor.add(RedColor) ;

RedColor.addSeparator() ; ;

Answer 1

double semicolons on the last line??
RedColor.add(RedColor) - a mistake?? you are adding the object RedColor to itself??

Answer 2

On another issue, you may want to call setVisible(true); so the window actually appears visible.
