What are real life examples of OOP concepts? ›

Think of objects as real-life entities. For instance, a car can be an object with properties like color, model, speed, and actions like accelerating and braking. In OOP, we encapsulate these properties and actions into a class entity.

An example of OOPs concept implementation in Java is creating a 'Car' class with attributes like 'make', 'model', and 'year', along with methods like 'start()', 'accelerate()', and 'stop()'.

Building complex systems and applications is made possible by OOPs, it enables modular, reusable, and maintainable programming. Software development, GUI development, game development, mobile app development, web development, database systems, and AI/ML are some of the main applications of OOPs.

Object-Oriented Programming & System (OOPSOOPSObject-oriented programming is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields, and code, in the form of procedures.) concepts in Java helps reduce code complexity and enables the reusability of code.

Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects.

For example, our Car class may have a repaint method that changes the color attribute of our car. This function is only helpful to objects of type Car , so we declare it within the Car class, thus making it a method. Class templates are used as a blueprint to create individual objects.

OOP is based on the idea of "objects," which are self-contained units of code that have both data and behavior. This allows us to create code that closely mirrors the real-world objects and concepts that we are trying to model.

Abstraction in Real Life

Your car is a great example of abstraction. You can start a car by turning the key or pressing the start button. You don't need to know how the engine is getting started, what all components your car has. The car internal implementation and complex logic is completely hidden from the user.

Objects are key to understanding object-oriented technology. Look around right now and you'll find many examples of real-world objects: your dog, your desk, your television set, your bicycle. Real-world objects share two characteristics: They all have state and behavior.

Procedural Programming is the use of code in a step-wise procedure to develop applications. For example, to develop a simple Bank Account App procedurally: Creating an account for an individual ( account ) Getting an account to deposit or withdraw funds ( getAccount , deposit , withdraw )

What are the 5 applications of OOP? ›

Object-Oriented Programming (OOPs) has emerged as a critical paradigm in current software development. Its uses include software development, graphical user interface development, game development, database management systems, and mobile application development.

1y. Object-oriented programming (OOP) is a programming paradigm that uses "objects" and their interactions to design applications and computer programs. Real-world examples of OOP concepts include objects such as a car, a person, and a bank account.

Object-oriented programming: Refers to the practice of defining classes and objects to organize code, and is used in most programming languages today. There are three major pillars on which object-oriented programming relies: encapsulation, inheritance, and polymorphism. Phew!

Abstraction, encapsulation, polymorphism, and inheritance are the four main theoretical principles of object-oriented programming. But Java also works with three further OOP concepts: association, aggregation, and composition.

Procedural Programming is the use of code in a step-wise procedure to develop applications. For example, to develop a simple Bank Account App procedurally: Creating an account for an individual ( account ) Getting an account to deposit or withdraw funds ( getAccount , deposit , withdraw )

Similarly, let's understand polymorphism with a real-life example. Consider a person, who can have multiple characteristics at a time, the person can be a father, a son, and an employee at the same time. The same person acts differently in different scenarios, this shows polymorphism.
