Object Oriented Software Development · Object-oriented software development is a programming · methodology that focuses on creating software based on the

concept of "objects." An object is an instance of a class,

which is a blueprint that defines the data and behavior of · the object. · Principles of object-oriented software development

Encapsulation: The concept of encapsulation involves bundling data and behavior together into a single unit, known as a class. The class hides the data and behavior from the outside world and provides an interface for interacting with the object. Inheritance: Inheritance is the process by which one class can inherit properties and behavior from another class. This enables developers to reuse code and avoid duplicating effort. Polymorphism: Polymorphism allows objects to take on multiple forms, meaning they can be used in different contexts with different behaviors. Abstraction: Abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts. In object-oriented software development, this is achieved through the use of abstract classes and interfaces. In object-oriented programming, a class is a blueprint for creating objects. A class defines a set of properties and behaviors that are common to all objects of that class. For example, a class might define the properties and behaviors of a car, such as its make, model, and color, as well as its ability to accelerate, brake, and turn. An object, on the other hand, is an instance of a class. When you create an object, you are creating a specific instance of a class, with its own unique set of properties and behaviors.
