Thanks for the explanation & pointers.
Smartphone is an abstract class but build() is defined & no abstract method is present....how does this work?

I tried with addOS() and addBranding() to the beginning of super.build()...
addOS() + super.build() to AndroidPhone, ApplePhone, and WindowsPhone
and addBranding() + super.build() to NokiaPhone
the 4 print messages to the console then would look like :-
Android OS v9.0 + Screen, Battery, Charger
IOS v10.0 + Screen, Battery, Charger
Nokia Phone with Windows OS v3.0 + Screen, Battery, Charger
Nokia Phone with Android OS v9.0 + Screen, Battery, Charger
