Answer / amol
No. In method overriding the behaviour of overrided method
is different. The subclass override only those methods,
which has different behaviour than superclass else alawys
use all the methods of superclass, which is better than
making a lot duplication by defining another class for same
methods of superclass.

Answer / venkat
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",
