Question

In Java, which comparison about Heap vs Stack is accurate?

  1. Stack memory follows method-invocation lifetimes, while heap memory survives until objects become unreachable.
  2. There is no practical difference in behavior, performance, or API design when Heap vs Stack is involved.
  3. The oldest option related to Heap vs Stack is always the right production choice regardless of context.
  4. Differences around Heap vs Stack 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: A. Stack memory follows method-invocation lifetimes, while heap memory survives until objects become unreachable.

Stack memory follows method-invocation lifetimes, while heap memory survives until objects become unreachable. This is the comparison that usually separates memorization from understanding.
