What Is the Primary Goal of Encapsulation in Software Design?
Encapsulation primarily hides implementation details in software design, exposing stable interfaces to enhance maintainability, security, and loose coupling between components.
Question
In software design, what is the primary goal of encapsulation?
A. To hide implementation details from users
B. To allow multiple inheritance
C. To increase code execution speed
D. To provide global access to variables
Answer
A. To hide implementation details from users
Explanation
Encapsulation bundles data and operations within a module or class, exposing only a controlled public interface while concealing internal implementation details through access modifiers, enabling changes to internal logic without affecting dependent code and promoting loose coupling, maintainability, and abstraction. This principle prevents direct manipulation of private state, enforces data integrity via validation methods, and supports information hiding critical to modular design, unlike enabling inheritance (B), performance optimization (C), or global access antithetical to its goals (D).
