Object-Oriented is a programming paradigm that focuses on the use of objects and their interactions to design and program applications. It is based on the concept of objects which contain data and methods that can be used to manipulate the data.
Object-oriented programming (OOP) is a programming paradigm that uses objects and their interactions to design applications and computer programs. It is a programming language model organized around objects rather than “actions” and data rather than logic. OOP is a way of thinking about programming that focuses on objects and their interactions with each other.
Objects are the basic building blocks of object-oriented programming. An object is a self-contained entity that contains both data and code. Objects are created from classes, which are templates that define the characteristics of an object. Objects can contain data, such as numbers, strings, and Booleans, as well as code, such as methods and functions. Objects can also contain other objects, which are known as sub-objects.
Objects interact with each other by sending messages. When an object sends a message to another object, it is known as a method call. The receiving object then responds to the message by executing the appropriate code. This is known as encapsulation, which is a key concept in object-oriented programming.
Object-oriented programming also makes use of inheritance, which is the ability of an object to inherit the characteristics of another object. This allows objects to share code and data, which makes programming more efficient.
Object-oriented programming is used in many different programming languages, such as Java, C++, and Python. It is a powerful programming paradigm that allows developers to create complex applications quickly and easily. It is also a great way to organize code and make it easier to maintain.
