Question: 1 / 400

What function do "getter" methods serve in object-oriented programming?

They initialize values of an object.

They fetch the value of an object's attribute.

Getter methods play a crucial role in object-oriented programming by providing a controlled way to access the values of an object's attributes. Specifically, they retrieve and return the value stored in a private or protected attribute. This encapsulation is an essential concept in object-oriented design, which promotes data hiding and ensures that the internal state of an object can only be modified through well-defined interfaces.

By using getter methods, a class can expose certain attributes to the outside without allowing direct access, thereby maintaining the integrity of the data. This control over attribute access can also allow for additional logic to be implemented when values are fetched, such as validation or transformation, which can be beneficial in maintaining the overall behavior of an application. Thus, option B accurately captures the primary function of getter methods in an object-oriented context.
