Which concept describes the ability of objects of different types to be accessed through the same interface?

The concept that describes the ability of objects of different types to be accessed through the same interface is known as polymorphism. This principle allows methods to perform actions on objects of different classes as if they were of the same type, which simplifies code and enhances flexibility.

In programming, polymorphism enables a single function or method to operate on different types of data. For instance, if you have a method designed to handle shapes, you could use polymorphism to ensure that it can process all shapes—like circles, squares, and triangles—through a unified interface. This feature is particularly valuable in object-oriented programming, as it allows for the creation of more generic and reusable code.

The other concepts, while important in object-oriented programming, do not specifically encapsulate the ability to access different types through the same interface. Inheritance relates to how classes derive properties and methods from other classes, abstraction concerns hiding complex details and exposing only essential features, and encapsulation focuses on bundling data with the methods that operate on it. Each of these concepts plays a distinct role but does not directly address the capability provided by polymorphism.
