Understanding OOP Principles

What is encapsulation in OOP?

• Encapsulation is the process of creating multiple instances of a class.

• Encapsulation is the bundling of data and methods that operate on that data, restricting direct access to some of the object's components.

• Inheritance is a way to create a new class without any attributes.

• Inheritance allows a class to delete attributes from another class.

• Inheritance is a method for classes to operate independently of each other.

• Inheritance is a mechanism for a new class to inherit attributes and methods from an existing class.

What does polymorphism allow in OOP?

• Polymorphism restricts method access in OOP.

• Polymorphism allows for method overriding and dynamic method resolution in OOP.

• Polymorphism enforces a single method implementation in OOP.

• Polymorphism eliminates the need for inheritance in OOP.

What is the purpose of abstraction in OOP?

• To ensure all classes are tightly coupled.

• To enhance security by encrypting data.

• To eliminate the need for interfaces in programming.

• The purpose of abstraction in OOP is to reduce complexity and increase efficiency by hiding unnecessary details.

What is method overriding in the context of OOP?

• Method overriding is when a method is deleted from a subclass.

• Method overriding is a feature that allows multiple methods with the same name in a class.

• Method overriding is when a superclass redefines a method from its subclass.
