If the annotation`@Documented`is present on the declaration of an annotation interface*A* , then any`@A`annotation on an element is considered part of the element's public contract. In more detail, when an annotation interface*A* is annotated with`Documented`, the presence and value of*A* annotations are a part of the public contract of the elements*A* annotates. Conversely, if an annotation interface*B* is*not* annotated with`Documented`, the presence and value of*B* annotations are*not* part of the public contract of the elements*B* annotates. Concretely, if an annotation interface is annotated with`Documented`, by default a tool like javadoc will display annotations of that interface in its output while annotations of annotation interfaces without`Documented`will not be displayed.
