Question

In Java, which comparison about Encapsulation is accurate?

  1. There is no practical difference in behavior, performance, or API design when Encapsulation is involved.
  2. The oldest option related to Encapsulation is always the right production choice regardless of context.
  3. Differences around Encapsulation are mostly cosmetic, so correctness and maintainability do not change.
  4. Good encapsulation exposes behavior-focused methods rather than raw unrestricted field mutation.

Hint

Focus on the behavior or tradeoff, not just the keyword.

Answer and rationale

Correct answer: D. Good encapsulation exposes behavior-focused methods rather than raw unrestricted field mutation.

Good encapsulation exposes behavior-focused methods rather than raw unrestricted field mutation. This is the comparison that usually separates memorization from understanding.
