What term is used for properties shared between multiple classes in object-oriented programming?

The correct term for properties shared between multiple classes in object-oriented programming is interfaces. Interfaces define a contract that classes can implement, ensuring that they adhere to a common set of properties and methods. This promotes a level of abstraction, allowing different classes to be treated uniformly based on the interface they implement, even if they are otherwise unrelated in their internal structure.

Attributes generally refer to the characteristics or properties of a specific class instance, not something that is shared across multiple classes. Methods pertain to the actions or behaviors defined by a class, while functions are standalone blocks of code that may not be inherently tied to a class structure. Interfaces specifically facilitate shared properties and behaviors among various classes, strengthening code reusability and modular design.
