Question

In Java, which comparison about Arrays and Indexed Access is accurate?

  1. There is no practical difference in behavior, performance, or API design when Arrays and Indexed Access is involved.
  2. Arrays are strongest when indexed reads and sequential scans matter, while linked structures trade locality for easier pointer-based updates.
  3. The oldest option related to Arrays and Indexed Access is always the right production choice regardless of context.
  4. Differences around Arrays and Indexed Access 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. Arrays are strongest when indexed reads and sequential scans matter, while linked structures trade locality for easier pointer-based updates.

Arrays are strongest when indexed reads and sequential scans matter, while linked structures trade locality for easier pointer-based updates. This is the comparison that usually separates memorization from understanding.
