Explanation: Allowing a class to inherit the properties and methods of another class is called Inheritance.

Explanation:
Report for correction10. Polymorphism allows objects of different classes to be treated as objects of a common _______?
Explanation: Polymorphism allows objects of different classes to be treated as objects of a common Super class.
Report for correction11. In OOPS; an object is an instance of what?
Explanation: Object is an instance of a class that has its own state and access to all of the behaviour defined by its class.

Explanation:
Report for correction13. Which OOPS principle encourages the separation of a complex system into smaller; manageable classes and objects?
Explanation: Abstraction is a act of representing complex systems or ideas in a simplified way that can be easily understood
Report for correction14. In OOPS; a method that has the same name as the class and is automatically called when an object is created is called as what?
Explanation:
Report for correction15. Which OOPS concept allows you to define default implementations for methods in an interface?
Explanation:
Report for correction16. Which OOPS concept allows you to define a contract that specifies a set of methods a class must implement?
Explanation:
Report for correction17. Which keyword is used to indicate that a method in a subclass is intended to override a method in the superclass?
Explanation:
Report for correction18. 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.
