Question
When should a Java developer choose Type Erasure deliberately?
- Design APIs with explicit type tokens or metadata when runtime generic type discovery is genuinely required.
- Choose Type Erasure mainly when you want to postpone validation and fix problems manually later.
- Choose Type Erasure whenever you want the code to look more advanced, even if the design gets less clear.
- Choose Type Erasure 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: A. Design APIs with explicit type tokens or metadata when runtime generic type discovery is genuinely required.
Design APIs with explicit type tokens or metadata when runtime generic type discovery is genuinely required. Interviewers often ask this to see whether you can connect the concept to real design decisions.
