<description>
Fields in interfaces are automatically public static final, and methods are public abstract.
Classes or interfaces nested in an interface are automatically public and static (all nested interfaces are automatically static).
Fields in interfaces and annotations are automatically `public static final`, and methods are `public abstract`.
Classes, interfaces or annotations nested in an interface or annotation are automatically `public static`
(all nested interfaces and annotations are automatically static).
Nested enums are automatically `static`.
For historical reasons, modifiers which are implied by the context are accepted by the compiler, but are superfluous.
