Question

What deeper point about NIO Files and Path should a senior Java developer mention?

  1. At senior level, the right answer is that NIO Files and Path exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around NIO Files and Path, so design choices barely matter.
  3. Robust file code accounts for permissions, symbolic links, large directories, and failure modes as system concerns rather than helper-method details.
  4. At senior level, any approach to NIO Files and Path is equally correct if it compiles and passes a small test.

Hint

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

Answer and rationale

Correct answer: C. Robust file code accounts for permissions, symbolic links, large directories, and failure modes as system concerns rather than helper-method details.

Robust file code accounts for permissions, symbolic links, large directories, and failure modes as system concerns rather than helper-method details. This is the kind of tradeoff-aware answer senior interviews usually expect.
