Abstraction vs. Encapsulation
Abstraction hides the complex reality while showing the essential features, while encapsulation bundles the data and methods that operate on the data.
Difference Between Abstraction and Encapsulation
In the realm of object-oriented programming (OOP), abstraction and encapsulation are fundamental concepts, albeit distinct in their nature and purpose. Abstraction is primarily about simplifying complex reality by focusing on relevant details, allowing developers to build layers in a way that each layer hides unnecessary details from the layers above. In simpler words, abstraction is the concept of hiding the complex reality and showing only the necessary features of an object, thereby reducing complexity.
In essence, while both abstraction and encapsulation deal with hiding details, they do so with different intents. Abstraction hides details to manage complexity, whereas encapsulation hides details to protect the integrity of data.
Encapsulation, conversely, is the bundling of data (attributes) with the methods (functions) that operate on that data. It restricts direct access to an object’s data, and can prevent the accidental modification of data. Encapsulation works as a protective shield that prevents the data from being accessed and modified by outside functions, making it a mechanism to impose data hiding and protection.
Both abstraction and encapsulation are cornerstone concepts in OOP, aiming to achieve modularity and clarity in code. While abstraction offers a clear hierarchy and promotes the reuse of code by focusing on the generalized view of things, encapsulation ensures that an object's internal workings are shielded from outside interference, upholding the integrity of the data.
A major difference in their applications is evident in their goals: abstraction aims to reduce and manage complexity by isolating unrelated details, whereas encapsulation aims to ensure data integrity by restricting access. This is akin to understanding a machine: abstraction would let you know its functions without knowing its internal complexities, and encapsulation would ensure that its internal parts aren't easily tampered with.

The act of abstracting, separating, withdrawing, or taking away; withdrawal; the state of being taken away.
To become encapsulated.
(euphemistic) The taking surreptitiously for one's own use part of the property of another; purloining.
The act of enclosing in a capsule; the growth of a membrane around (any part) so as to enclose it in a capsule.
(engineering) Removal of water from a river, lake, or aquifer.
Grouping together an object’s ‘state’ (its data) and the operations that may alter or interrogate it (its methods).
A separation from worldly objects; a recluse life; the withdrawal from one's senses.
a hermit's abstraction
(networking) The process of arranging data into packets that can be transmitted using a given protocol.
The act of focusing on one characteristic of an object rather than the object as a whole group of characteristics; the act of separating said qualities from the object or ideas.
Abstraction is necessary for the classification of things into genera and species.
The act of inclosing in a capsule; the growth of a membrane around (any part) so as to inclose it in a capsule.
Any characteristic of an individual object when that characteristic has been separated from the object and is contemplated alone as a quality having independent existence.
the condition of being enclosed (as in a capsule);
the encapsulation of tendons in membranous sheaths
A member of an idealized subgroup when contemplated according to the abstracted quality which defines the subgroup.
the process of enclosing (as in a capsule)
The act of comparing commonality between distinct objects and organizing using those similarities; the act of generalizing characteristics; the product of said generalization.
Restricting direct access to an object's internal details.
Encapsulation ensures only authorized functions modify the object's data.
An idea or notion of an abstract or theoretical nature.
to fight for mere abstractions.
Absence or absorption of mind; inattention to present objects; preoccupation.
(art) An abstract creation, or piece of art; qualities of artwork that are free from representational aspects.
(chemistry) A separation of volatile parts by the act of distillation.
An idea of an idealistic, unrealistic or visionary nature.
The result of mentally abstracting an idea; the product of any mental process involving a synthesis of: separation, despecification, generalization, and ideation in any of a number of combinations.
(geology) The merging of two river valleys by the larger of the two deepening and widening so much so, as to assimilate the smaller.
(computing) Any generalization technique that ignores or hides details to capture some kind of commonality between different instances for the purpose of controlling the intellectual complexity of engineered systems, particularly software systems.
(computing) Any intellectual construct produced through the technique of abstraction.
The act of abstracting, separating, or withdrawing, or the state of being withdrawn; withdrawal.
A wrongful abstraction of wealth from certain members of the community.
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.

A separation of volatile parts by the act of distillation.
