Question

In Java, which comparison about Garbage Collection is accurate?

  1. There is no practical difference in behavior, performance, or API design when Garbage Collection is involved.
  2. Eligibility for collection depends on reachability, not merely on a variable going out of scope in source code.
  3. The oldest option related to Garbage Collection is always the right production choice regardless of context.
  4. Differences around Garbage Collection 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. Eligibility for collection depends on reachability, not merely on a variable going out of scope in source code.

Eligibility for collection depends on reachability, not merely on a variable going out of scope in source code. This is the comparison that usually separates memorization from understanding.
