- Class: A class is a user-defined data type. It consists of data members and member functions, which can be accessed and used by creating an instance of that class.
- Object: It is a basic unit of Object-Oriented Programming and represents the real-life entities. An Object is an instance of a Class. When a class is defined, no memory is allocated but when it is instantiated (i.e.
- Data Abstraction: Data abstraction is one of the most essential and important features of object-oriented programming. Data abstraction refers to providing only essential information about the data to the outside world, hiding the background details or implementation.
- Encapsulation: Encapsulation is defined as the wrapping up of data under a single unit. It is the mechanism that binds together code and the data it manipulates.

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.

Now that we have covered the basic prerequisites, we will move on to the 4 pillars of OOPswhich are as follows. But, let us start by learning about the different characteristics of an Object-Oriented Programming Language. OOPS concepts are as follows: 1. Class 2. Object 3. Pillars of OOPs 3.1. Abstraction 3.2. Encapsulation 3.3. Inheritance 3.4. Po...
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
Object-oriented programming (OOP) offers several key advantages over procedural programming: 1. OOP promotes code reusability: By using objects and classes, you can create reusable components, leading to less duplication and more efficient development. 2. OOP enhances code organization: It provides a clear and logical structure, making the code eas...
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...
Feb 11, 2022 · Learn the basic principles of object-oriented programming (OOPS) and how to apply them in software development. See examples of classes, objects, methods, and instances in different languages and scenarios.
Sep 6, 2022 · In basic terms, OOP is a programming pattern that is built around objects or entities, so it's called object-oriented programming. To better understand the concept, let's have a look at commonly used software programs: A good example to explain this would be the use of a printer when you are printing a document.
May 20, 2024 · Object-Oriented Programming (OOP) is a programming paradigm in computer science that relies on the concept of classes and objects. It is used to structure a software program into simple, reusable pieces of code blueprints (usually called classes), which are used to create individual instances of objects.
