Can it be considered that abstraction and interface mean the same thing in object-oriented programming?

Abstraction and interface in object-oriented programming are related but not the same.

• Abstraction is a principle that allows highlighting the important characteristics of an object while hiding implementation details. It is a concept that helps focus on what the object does, not how.

• Interface is a specific way of implementing abstraction, defining a set of methods that a class must implement but not containing their implementation.

For example, in Dart (Flutter), an interface is defined through an abstract class with methods without implementation. Thus, an interface is a tool for implementing abstraction, but abstraction is broader in meaning.
