FAQs on What is Object Oriented Programming (OOP) Video Lecture - Crash Course for EmSAT Achieve

1. What is Object Oriented Programming (OOP)?
Ans. Object Oriented Programming (OOP) is a programming paradigm that organizes data and behaviors into reusable structures called objects. It focuses on creating objects, which are instances of classes, and allows for the implementation of concepts like encapsulation, inheritance, and polymorphism.
2. What is the difference between POP and OOP?
Ans. Procedural Programming (POP) is a programming paradigm that follows a linear top-down approach, where the program is divided into functions or procedures that operate on data. On the other hand, Object Oriented Programming (OOP) focuses on creating objects that encapsulate data and behaviors, promoting code reusability and modularity.
3. How does OOP promote code reusability?
Ans. OOP promotes code reusability through the concept of inheritance. Inheritance allows classes to inherit properties and behaviors from other classes, known as parent or base classes. By reusing existing classes as base classes, developers can save time and effort by inheriting common functionalities and only implementing specific features in derived classes.
4. What is encapsulation in OOP?
Ans. Encapsulation is a fundamental concept in OOP that involves bundling of data and methods within a class. It allows the class to control the access to its data, ensuring data integrity and security. Encapsulation also provides a way to hide the implementation details of a class and only expose necessary methods or properties to interact with the object.
5. How does OOP support polymorphism?
Ans. Polymorphism is a feature of OOP that allows objects of different classes to be treated as objects of a common superclass. This means that different classes can have their own implementations of methods with the same name, and the appropriate method is called based on the type of object invoking it. Polymorphism enables code to be more flexible and adaptable, as it can work with objects of different types through a common interface.
