Abstraction vs interface

Question

Accepted Answer

Abstraction is hiding the implementation details while interface is a contract that defines the methods that a class must implement.

Abstraction focuses on hiding the internal implementation details of a class, allowing the user to only interact with the public methods.
Interface defines a set of methods that a class must implement, ensuring consistency and providing a way for different classes to be used interchangeably.
Abstraction can be achieved through abstract classes in languages like Java, while interfaces are a separate construct used for defining contracts.
Abstraction allows for flexibility in changing the internal implementation without affecting the external code, while interfaces enforce a specific set of methods to be implemented.
