Answer
Annotations retained at runtime can be accessed via reflection.
RetentionPolicy.RUNTIME indicates that annotations should be accessible during program execution, enabling dynamic behavior based on these annotations. For example, in a mini-Spring Boot framework, a custom @Route annotation can define URL mappings that are processed at runtime using reflection.
