Abstractions are a concept used in computing and programming to aid in developing algorithms. An abstraction hides the underlying implementation details behind a simple interface, so that a programmer can focus on solving the problem rather than worrying about low-level implementation details. In object-oriented programming, abstractions are most often represented by abstract classes and interfaces, as these provide a mechanism for a programmer to explicitly define the obligations of a software system. When used correctly, abstractions can help limit complexity, improve readability, and enable reuse. Abstractions are also used extensively in mathematics and philosophy, as they allow us to map complex concepts down to a simpler form.
