Question
When should a Java developer choose java.time API deliberately?
- Choose java.time API mainly when you want to postpone validation and fix problems manually later.
- Use LocalDate for business dates and Instant for system timestamps such as event creation time.
- Choose java.time API whenever you want the code to look more advanced, even if the design gets less clear.
- Choose java.time API 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: B. Use LocalDate for business dates and Instant for system timestamps such as event creation time.
Use LocalDate for business dates and Instant for system timestamps such as event creation time. Interviewers often ask this to see whether you can connect the concept to real design decisions.
