Object-Oriented Programming (OOP) is a programming paradigm that has become increasingly popular in recent years. Many companies use OOP in their software development projects, so it's important to have a good understanding of its features and characteristics for job interviews.
Here are some important features of OOP that you should know for job interviews:
Encapsulation: This is the process of hiding the implementation details of an object from the outside world, while still allowing access to its functionality. Encapsulation is achieved through the use of access modifiers such as private, protected, and public.
Inheritance: This is the ability of a subclass to inherit the properties and methods of its superclass. Inheritance allows for code reuse and promotes consistency and standardization in object design.
Polymorphism: This is the ability of an object to take on multiple forms or have multiple behaviors. Polymorphism is achieved through method overriding and method overloading.
Abstraction: This is the process of defining the essential features of an object while ignoring its non-essential details. Abstraction is achieved through the use of abstract classes and interfaces.
Classes and Objects: OOP is based on the concept of classes and objects. A class is a blueprint or template for creating objects, while an object is an instance of a class.
Modularity: OOP promotes modularity by breaking down a system into smaller, more manageable parts. Each part is designed to perform a specific task, making the system easier to understand, maintain, and modify.
Message Passing: In OOP, objects communicate with each other by sending messages. A message is a request for an object to perform a specific action, and the object responds by executing the requested action.
Overriding: This is the process of replacing a method in the superclass with a new implementation in the subclass. Overriding allows for customization and flexibility in object design.
Overloading: This is the process of creating multiple methods with the same name but different parameters. Overloading allows for code reuse and promotes consistency and standardization in object design.
Knowing these features and characteristics of OOP will help you answer interview questions more confidently and demonstrate your understanding of this programming paradigm. We Make sure to practice implementing these concepts in code, and be prepared to explain how they work in practical situations.
