Question

the actual type of a reference variable has no role in determining which method to match along the inheritance chain True/False

Answer 1

The method to match along the inheritance chain does not depend on the actual type of a reference variable True.

whenever a method is defined that overrides another method?

Since a subclass can override a method, a class can inherit from a superclass whose behavior is "near enough" and then change it as necessary. The overriding method uses the same name, number, and kind of parameters.

What operator is employed to ascertain whether an object belongs to a specific class type?

If an object is an instance of the supplied type, the Java "instanceof" operator is used to check this (class or subclass or interface). As a result of comparing instances and types, it is also known as a type comparison operator.
