Question

In Java, which comparison about Queue Fundamentals is accurate?

  1. There is no practical difference in behavior, performance, or API design when Queue Fundamentals is involved.
  2. Queues preserve arrival order, while stacks reverse it and priority queues reorder by priority rules.
  3. The oldest option related to Queue Fundamentals is always the right production choice regardless of context.
  4. Differences around Queue Fundamentals 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. Queues preserve arrival order, while stacks reverse it and priority queues reorder by priority rules.

Queues preserve arrival order, while stacks reverse it and priority queues reorder by priority rules. This is the comparison that usually separates memorization from understanding.
