Question
When should a Java developer choose Collisions and Load Factor deliberately?
- Choose Collisions and Load Factor mainly when you want to postpone validation and fix problems manually later.
- Choose Collisions and Load Factor whenever you want the code to look more advanced, even if the design gets less clear.
- Discuss load factor when sizing a hash-based structure for expected traffic instead of waiting for repeated rehashing under load.
- Choose Collisions and Load Factor only to avoid modeling domain rules explicitly in Java code.
Hint
Think about the production scenario where the choice genuinely improves the code.
Answer and rationale
Correct answer: C. Discuss load factor when sizing a hash-based structure for expected traffic instead of waiting for repeated rehashing under load.
Discuss load factor when sizing a hash-based structure for expected traffic instead of waiting for repeated rehashing under load. Interviewers often ask this to see whether you can connect the concept to real design decisions.
