To understand the Question, one needs to know the scenarios
where in a method is overriden.
there are two cases:
you want to override a method:
1)when the super class doesnt know how to implement it, and
leaves the implementation to the sub-class.
2)when the subclass feels, it has to add few more details
specific to itself than which are provided by the
superclass.

so there is no duplication happening provided one overrides
a method sensibly(understanding thorougly if overriding a
method is necessary or not).if one wishes to write things
that are already available, it is then called "duplication
of code",
