What are some real-world examples of abstraction and encapsulation?

Abstraction is simplifying complex systems by hiding unnecessary details. For example, a car's dashboard shows speed and fuel level without revealing engine mechanics. Encapsulation, on the other hand, restricts access to certain components. A good example is a bank account, where the internal balance is hidden, and users interact through methods like deposit and withdrawal.

Can you explain how abstraction is used in software development?

In software development, abstraction allows developers to create complex systems by focusing on high-level functionalities. For instance, in object-oriented programming, classes represent real-world entities, and their methods provide a simplified interface for interaction, hiding the underlying implementation details.

What about encapsulation? How does it help in programming?

Encapsulation helps in programming by bundling data and methods that operate on that data within a single unit, or class. This protects the integrity of the data by preventing outside interference and misuse, making the code more modular and easier to maintain.

Can you give me an example of encapsulation in a programming language?

Sure! In Java, you can use private variables in a class to encapsulate data. For example, a class 'Person' might have a private variable 'age' and public methods 'getAge()' and 'setAge()' to access and modify it, ensuring that age cannot be set to a negative value.
