Question

In Java, which comparison about Stack Fundamentals is accurate?

  1. There is no practical difference in behavior, performance, or API design when Stack Fundamentals is involved.
  2. The oldest option related to Stack Fundamentals is always the right production choice regardless of context.
  3. Stacks model nested or backtracking work, while queues model first-come, first-served processing.
  4. Differences around Stack 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: C. Stacks model nested or backtracking work, while queues model first-come, first-served processing.

Stacks model nested or backtracking work, while queues model first-come, first-served processing. This is the comparison that usually separates memorization from understanding.
