Abstraction vs. Encapsulation — What's the Difference?
By Tayyaba Rehman — Published on October 10, 2023
Abstraction is simplifying complex reality by modeling classes appropriate to the problem, and working at the most relevant level of inheritance; encapsulation is hiding the internal states and require all interaction to be performed through an interface.

Key Differences
In object-oriented programming, abstraction is fundamental in creating class hierarchies and defining objects at various levels of detail, enabling polymorphism and inheritance. It is a way to manage and reduce complexity by working at the most relevant level of inheritance. Encapsulation, in contrast, is about creating a clear boundary around objects, defining a strict interaction protocol, and protecting the object’s internal state from external interference, ensuring data integrity and security.

Abstraction can be seen as a design philosophy, focusing on creating simplified, relevant models of more complex entities, reducing cognitive load. It allows us to handle and reason about complex systems at a high level, without getting bogged down by details. Encapsulation, meanwhile, is more of a technique, providing a clear structure and helping in maintaining the integrity of the system by preventing external components from interacting with the internal state other than through specified methods.

Abstraction allows us to create a simplified representation of an object, focusing only on its essential characteristics and behavior, and omitting the complex details. This abstraction process allows for clearer, more understandable, and manageable code. Conversely, encapsulation is ensuring that the object's internal state is hidden, exposing only what is necessary through a well-defined interface. It’s a protective barrier that keeps the data safe within the object and prevents outside code from directly accessing it.

Abstraction, in computer science, refers to the concept of simplifying complex systems, hiding unnecessary details to focus only on relevant high-level features. It is about conceptualizing and modeling, enabling us to understand and manage complexity. Encapsulation, on the other hand, is about concealing the internal details of objects and revealing only what is necessary. It is a mechanism to restrict direct access to some of the object's components and can prevent unintended interference and misuse.

Abstraction
Abstraction in its main sense is a conceptual process where general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods. "An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts, and connects any related concepts as a group, field, or category.Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only the aspects which are relevant for a particular subjectively valued purpose.

Abstraction
The act process of leaving out of consideration one or more properties of a complex object so as to attend to others; analysis. Thus, when the mind considers the form of a tree by itself, or the color of the leaves as separate from their size or figure, the act is called abstraction. So, also, when it considers whiteness, softness, virtue, existence, as separate from any particular objects.
Abstraction is no positive act: it is simply the negative of attention.
