Answer 1

Regarding

....and i IMAGINE that the field "child" in SpecialContainer is automatically overloading the field 'child' of the GenericContainer...

No. Fields don't get overridden, only methods do.

This is one reason why use of (overridable) getter and setter methods are preferred to direct access to fields. Your fields should almost all be private.

As for your design, there's no need for your SpecialContainer class to have a SpecialChild field, but instead the SpecialChild object should be placed in the GenericChild field.
