Question

What deeper point about TreeMap and NavigableMap should a senior Java developer mention?

  1. The strong interview answer is that ordered maps are about navigation power, not just about making printed output look sorted.
  2. At senior level, the right answer is that TreeMap and NavigableMap exists mostly for historical syntax reasons.
  3. At senior level, the JVM removes the tradeoffs around TreeMap and NavigableMap, so design choices barely matter.
  4. At senior level, any approach to TreeMap and NavigableMap 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: A. The strong interview answer is that ordered maps are about navigation power, not just about making printed output look sorted.

The strong interview answer is that ordered maps are about navigation power, not just about making printed output look sorted. This is the kind of tradeoff-aware answer senior interviews usually expect.
