Question

What deeper point about java.time API should a senior Java developer mention?

  1. At senior level, the right answer is that java.time API exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around java.time API, so design choices barely matter.
  3. At senior level, any approach to java.time API is equally correct if it compiles and passes a small test.
  4. Time bugs usually come from ambiguous timezone and daylight-saving boundaries, not from the basic syntax of the API.

Hint

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

Answer and rationale

Correct answer: D. Time bugs usually come from ambiguous timezone and daylight-saving boundaries, not from the basic syntax of the API.

Time bugs usually come from ambiguous timezone and daylight-saving boundaries, not from the basic syntax of the API. This is the kind of tradeoff-aware answer senior interviews usually expect.
