One of the add() methods defined in the Container class has the following signature.
Component add(Component comp)
Adds the specified component to the end of this container.

Since Menu is not a type of Component. (i.e. Menu doesnot inherit from Component, inherits from MenuComponent), it cannot be used to invoke the add() method of Container class, hence cannot be added to a Container.
