Is it compulsory to override the methods equals() and hashCode() for final classes?

Thanks in advance

is it compulsary to override equals and hashCode methods for classes which are defined as final?

Define a class as final and overriding equals() and hashCode() are two different things.

Final is there to restrict a class not to be sub classed. And, equals() is there to check the equality of the instances of a class.
