What is encapsulation, data hiding and abstraction?

Question

Accepted Answer

Encapsulation is the bundling of data and methods into a single unit. Data hiding is the concept of restricting access to data. Abstraction is the process of simplifying complex systems.

Encapsulation combines data and methods into a single unit, providing better control and security.
Data hiding restricts access to data, allowing only specific methods to manipulate it.
Abstraction simplifies complex systems by providing a high-level view, hiding unnecessary details.
Example: A class in object-oriented programming encapsulates data (attributes) and methods (functions) that operate on that data.
Example: Private variables in a class can be used to hide sensitive information from external access.
Example: Abstract classes or interfaces in Java provide a way to define common behavior without specifying implementation details.
