Question: Suppose you are defining a class called Menu GUI that is a derived class of the class J Frame. Write code to add the menu item m Item to the menu m. Then add m to the menu bar m Bar, and then add the menu bar to the J Frame Menu GUI. Assume that this all takes place inside a constructor for Menu GUI. Also assume that everything has already been constructed with new, and that all necessary listeners are registered. You just need to do the adding.
