What is abstraction in programming languages?

Abstraction is a fundamental concept in programming that involves hiding complex implementation details and exposing only the necessary parts of an object or function. It allows developers to focus on high-level functionality without worrying about the underlying code.

Can you give examples of abstraction in different programming languages?

Sure! In Java, abstraction is achieved through abstract classes and interfaces. In Python, you can use abstract base classes from the abc module. C++ also supports abstraction through abstract classes and pure virtual functions.

Why is abstraction important in software development?

Abstraction is important because it simplifies code management, enhances code reusability, and improves maintainability. It allows developers to work on different parts of a program without needing to understand every detail of the entire system.

How does abstraction differ from encapsulation?

Abstraction focuses on hiding the complexity of the system by exposing only the necessary features, while encapsulation is about bundling the data and methods that operate on the data within a single unit, restricting access to some of the object's components.
