Question

What deeper point about Singly Linked Lists should a senior Java developer mention?

  1. At senior level, the right answer is that Singly Linked Lists exists mostly for historical syntax reasons.
  2. A senior answer mentions that theoretical insertion benefits disappear if the code must first walk many nodes to reach the update point.
  3. At senior level, the JVM removes the tradeoffs around Singly Linked Lists, so design choices barely matter.
  4. At senior level, any approach to Singly Linked Lists 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 mentions that theoretical insertion benefits disappear if the code must first walk many nodes to reach the update point.

A senior answer mentions that theoretical insertion benefits disappear if the code must first walk many nodes to reach the update point. This is the kind of tradeoff-aware answer senior interviews usually expect.
