is a fundamental concept in computer science that allows us to simplify complex systems by focusing on the essential aspects while hiding the details. is a technique used to manage and manipulate complex data structures by representing them as simpler entities. With data abstraction, we can define es, which serve as blueprints for creating objects that inherit their properties and behaviors.
An abstract class is a class that cannot be instantiated. It provides a base structure for subclasses to inherit from, defining common attributes and methods. s, on the other hand, refer to high-level data structures with associated operations, where the implementation details are concealed, and only essential functionalities are exposed.
In object-oriented programming, an is a method defined in an abstract class or interface, without any implementation details. Subclasses must provide a concrete implementation of these abstract methods. This approach promotes code reusability and allows for more flexibility in designing class hierarchies.
Another application of abstraction is seen in the representation of program syntax through an (AST). This hierarchical structure captures the essential components and relationships of a program, enabling analysis and transformation.
In software engineering, the pattern is used to provide an interface for creating families of related or dependent objects without specifying their concrete classes. It promotes loose coupling and flexibility in creating objects, adhering to the open-closed principle.
To enhance modularity and maintainability, an provides an interface between higher-level and lower-level components, shielding the upper layer from the complexity of the lower one. This promotes separation of concerns and allows for easier maintenance and upgrades.
focuses on hiding the implementation details of a procedure or function, allowing the caller to manipulate it without understanding its internal workings. This concept promotes code reuse, maintainability, and readability.
Lastly, refers to the representation of an object or idea in a simplified, distilled, or non-literal form. It allows artists to convey emotions, concepts, or messages through the removal of unnecessary details, stimulating the viewer's imagination and interpretation. Abstraction in art challenges conventional representations and opens up possibilities for new expressions.
