Question

What deeper point about Heap vs Stack should a senior Java developer mention?

  1. At senior level, the right answer is that Heap vs Stack exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around Heap vs Stack, so design choices barely matter.
  3. At senior level, any approach to Heap vs Stack is equally correct if it compiles and passes a small test.
  4. Escape analysis and JIT optimization mean the mental model is useful but still more nuanced than the textbook summary.

Hint

Look beyond syntax and explain the runtime, API, or design consequence.

Answer and rationale

Correct answer: D. Escape analysis and JIT optimization mean the mental model is useful but still more nuanced than the textbook summary.

Escape analysis and JIT optimization mean the mental model is useful but still more nuanced than the textbook summary. This is the kind of tradeoff-aware answer senior interviews usually expect.
