Question

What deeper point about TreeSet and NavigableSet should a senior Java developer mention?

  1. At senior level, the right answer is that TreeSet and NavigableSet exists mostly for historical syntax reasons.
  2. A senior answer highlights that navigable sets are often chosen for boundary queries, not merely for sorted printing.
  3. At senior level, the JVM removes the tradeoffs around TreeSet and NavigableSet, so design choices barely matter.
  4. At senior level, any approach to TreeSet and NavigableSet 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: B. A senior answer highlights that navigable sets are often chosen for boundary queries, not merely for sorted printing.

A senior answer highlights that navigable sets are often chosen for boundary queries, not merely for sorted printing. This is the kind of tradeoff-aware answer senior interviews usually expect.
