Question

What deeper point about Type Erasure should a senior Java developer mention?

  1. At senior level, the right answer is that Type Erasure exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around Type Erasure, so design choices barely matter.
  3. Type erasure explains bridge methods, certain overload limitations, and why many frameworks ask for explicit Class or Type references.
  4. At senior level, any approach to Type Erasure 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. Type erasure explains bridge methods, certain overload limitations, and why many frameworks ask for explicit Class or Type references.

Type erasure explains bridge methods, certain overload limitations, and why many frameworks ask for explicit Class or Type references. This is the kind of tradeoff-aware answer senior interviews usually expect.
