Report for correction2. In OOPS; a method that is defined in a superclass and can be overridden by its subclasses is called as what?
Explanation: We can override superclass methods so that meaningful implementation of superclass method can be defined in subclass. This is also known as runtime polymorphism.

Explanation:
Report for correction5. Which OOPS principle encourages the separation of a complex system into smaller; manageable classes and objects?

Explanation:
Report for correction18. Which OOPS concept allows you to define a contract that specifies a set of methods a class must implement?
Explanation:
Report for correction19. In OOPS; an object is an instance of what?
