Encapsulation in Object-Oriented Programing(OOP)
Encapsulation is a fundamental concept in Object-Oriented Programming (OOP) that plays a crucial role in designing systems. It involves bundling data (attributes) and methods (functions) that operate on the data into a single unit, called a class. Here’s how encapsulation is used in designing systems:
- Definition:
- Encapsulation refers to the bundling of data and methods that manipulate the data into a single unit, known as a class. It allows for the implementation details of a class to be hidden from external users, who interact with the class through its public interface.
- Class as a Unit of Encapsulation:
- In OOP, classes serve as units of encapsulation. They encapsulate data (attributes) and behavior (methods) related to a specific entity or concept. Users of the class interact with it through its public methods, without needing to know the internal details of how those methods are implemented.
- Access Modifiers:
- Encapsulation is enforced through access modifiers, such as public, private, and protected, which control the visibility of class members (attributes and methods). Public members are accessible from outside the class, while private members are only accessible from within the class itself. This allows for better control over the access to and manipulation of the class’s internal state.
Object-Oriented Programing(OOP) Concepts for Designing Sytems
Object-oriented programming, or OOP, is like a set of tools that helps designers and developers create software systems. Think of it as a way to organize and build digital worlds piece by piece. In simpler words, OOP is a way of thinking and designing computer programs that mimic how we organize things in the real world. In this article, we’ll explore the core concepts of OOPs things like encapsulation, inheritance, polymorphism, and more—and see how they help us design better software systems.
