no both are not same thing
the meaning of classification in hindi is "bhag" that means type
and characteristics means in hindi is "vishestaye , guun "
so, we can say both are not same

Answer 2

No it is not
Let's take take example from biology
If We classify organism we can into :-
1). Monera
2). Protista
3). Fungi
4)plantae

But their characteristics are the features which define what they are.
