Answer
@Retention determines how long annotations are kept.
The @Retention annotation specifies whether annotations are available only in source code, in class files, or at runtime. This is crucial for determining if an annotation can be accessed via reflection. For instance, @Retention(RetentionPolicy.RUNTIME) allows runtime access, essential for frameworks that need to read annotations during execution.
