What defines the messages an object can receive in OOP?

Its methods
Its interface
Its class
Its variables

The correct answer is: Its interface

An object's interface dictates the messages that can be received by that specific object in Object Oriented Programming (OOP) whereas A, C, and D do not. Objects have methods which represent the behaviors they are capable of and a class that provides a template for creating objects. However, only the interface defines the available messages that an object can receive. A is incorrect because methods are simply a part of the interface and do not solely determine the available messages. C is incorrect because while a class defines the properties and behaviors of an object, it does not specifically dictate the messages the object can receive. D is incorrect because variables are used to store and manipulate data, and do not determine the messages an object can receive. In OOP, the interface is a crucial concept as it enforces encapsulation and effectively defines how an object can interact with other objects in a program.
