Question

Which practice avoids a common mistake with Collisions and Load Factor?

  1. Ignore the Collisions and Load Factor issue and rely on team discipline instead of APIs or contracts.
  2. Silence the Collisions and Load Factor problem by using raw types, broad catches, or shared mutable state.
  3. Prefer the version of Collisions and Load Factor that makes behavior less predictable as long as the code compiles.
  4. Do not assume collisions mean the hash table is broken; the real issue is how well collisions are distributed and handled.

Hint

Look for the option that protects correctness instead of hiding the problem.

Answer and rationale

Correct answer: D. Do not assume collisions mean the hash table is broken; the real issue is how well collisions are distributed and handled.

Do not assume collisions mean the hash table is broken; the real issue is how well collisions are distributed and handled. This is a common failure mode in real Java code and a frequent interview follow-up.
