# Annotation Interface Documented

@Documented @Retention(RUNTIME) @Target(ANNOTATION_TYPE) public @interface Documented
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.
