Answer
RetentionPolicies determine when annotations are available.
`RetentionPolicy.RUNTIME` keeps annotations available at runtime, essential for frameworks that use reflection to process annotations. For example, a custom annotation with RUNTIME retention can be used to mark methods that should be logged, and a framework can use reflection to scan and log these methods during execution.
