Which of the following best describes the concept of abstraction in object-oriented programming (OOP)?Â
Abstraction in OOP is a fundamental concept that involves hiding the complex internal details of a system and exposing only what is necessary to the user. This simplifies the interaction with objects and promotes reusability, as the user can interact with high-level methods without needing to understand their internal workings. It allows developers to create complex systems while maintaining a clear and simplified interface. In practical terms, abstraction can be achieved through the use of abstract classes and interfaces, where only the essential behavior is defined, and the details are hidden. Why other options are wrong: A) This describes encapsulation, not abstraction, which involves combining data and methods into a class. C) This is method overloading, where multiple methods share the same name but differ in parameters or implementation. D) This refers to inheritance and polymorphism, not abstraction. E) This describes polymorphism, which allows objects to behave differently based on the context.
