Explanation

Overriding requires identical method signatures including return type. Changing return type from int to long with the same parameters is not a valid override in Java. This causes a compiler error.

AI explanation

The subclass method has the same name and parameters as the superclass method but a different, non-covariant return type (long vs int). Java requires an overriding method's return type to be the same or a covariant (subtype) reference type — primitive widening like int to long doesn't count as covariant. This return-type clash is a compile-time error, so the code never runs.
