OOP stands for Object-Oriented Programming. Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods. Object-oriented programming has several advantages over procedural programming:

Data Abstractionis the property by virtue of which only the essential details are displayed to the user. The trivial or non-essential units are not displayed to the user. Ex: A car is viewed as a car rather than its individual components. Data Abstraction may also be defined as the process of identifying only the required characteristics of an obje...
It is defined as the wrapping up of data under a single unit. It is the mechanism that binds together the code and the data it manipulates. Another way to think about encapsulation is that it is a protective shield that prevents the data from being accessed by the code outside this shield. 1. Technically, in encapsulation, the variables or the data...
Inheritanceis an important pillar of OOP (Object Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features (fields and methods) of another class. We are achieving inheritance by using extendskeyword. Inheritance is also known as “is-a” relationship. Let us discuss some frequently used important termino...
It refers to the ability of object-oriented programming languages to differentiate between entities with the same name efficiently. This is done by Java with the help of the signature and declaration of these entities. The ability to appear in many forms is called polymorphism. E.g. Example
The Object Oriented Programming (OOPs) concept in Java is a powerful way to organize and write code. It uses key ideas like classes, objects, inheritance, polymorphism, encapsulation, and abstraction to create flexible and reusable code. By using the Java OOPs concept, programmers can build complex applications more efficiently, making the code eas...
Apr 18, 2022 · Today we are going to talk about object-oriented programming in Java. This article will help give you a thorough understanding of the underlying principles of object-oriented programming and its concepts.
Jan 25, 2024 · In this article, we’ll look into Object-Oriented Programming (OOP) concepts in Java. We’ll discuss classes, objects, abstraction, encapsulation, inheritance, and polymorphism. 2. Classes are the starting point of all objects, and we may consider them as the template for creating objects.
If you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code. This lesson will introduce you to objects, classes, inheritance, interfaces, and packages.
In this course, you’ll learn the foundations of object-oriented programming, write your own classes, create your own objects, and finally dive into some of the most common built-in Java classes.
