Abstraction
Understanding Abstraction
Abstraction is a fundamental concept in computer science and software engineering. It refers to the process of hiding the complex reality while exposing only the necessary parts. This simplification helps in managing complexity by allowing programmers to focus on interactions at a higher level without needing to understand all the details.
Importance of Abstraction
By using abstraction, developers can create more modular and maintainable code. It allows for the creation of abstract classes and interfaces that define a contract for other classes to implement, promoting code reuse and reducing redundancy.
