Question

In Java, which comparison about Annotations is accurate?

  1. There is no practical difference in behavior, performance, or API design when Annotations is involved.
  2. Some annotations exist mainly for compile-time tooling, while others are retained for runtime reflection.
  3. The oldest option related to Annotations is always the right production choice regardless of context.
  4. Differences around Annotations are mostly cosmetic, so correctness and maintainability do not change.

Hint

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

Answer and rationale

Correct answer: B. Some annotations exist mainly for compile-time tooling, while others are retained for runtime reflection.

Some annotations exist mainly for compile-time tooling, while others are retained for runtime reflection. This is the comparison that usually separates memorization from understanding.
