Java: Checked vs Unchecked Exceptions
Answer
Use a mix of checked and unchecked exceptions.
A reliable checkout flow should anticipate both recoverable and unrecoverable errors. Use checked exceptions for expected issues like payment failures, prompting retries or alternative actions. Unchecked exceptions can signify critical failures that might need logging and alerts. For example, a `PaymentDeclinedException` could be checked, while a `RuntimeException` for a critical system error would be unchecked.
