Question

In Java, which comparison about ArrayDeque as a Stack is accurate?

  1. There is no practical difference in behavior, performance, or API design when ArrayDeque as a Stack is involved.
  2. The oldest option related to ArrayDeque as a Stack is always the right production choice regardless of context.
  3. Differences around ArrayDeque as a Stack are mostly cosmetic, so correctness and maintainability do not change.
  4. ArrayDeque avoids the legacy baggage of Stack and is typically faster than linked alternatives for stack-style operations.

Hint

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

Answer and rationale

Correct answer: D. ArrayDeque avoids the legacy baggage of Stack and is typically faster than linked alternatives for stack-style operations.

ArrayDeque avoids the legacy baggage of Stack and is typically faster than linked alternatives for stack-style operations. This is the comparison that usually separates memorization from understanding.
