静态和非静态注释有什么区别？
What's is the difference between a static and non-static annotation?
Java 的内部 classes 可以是静态的也可以是非静态的。非静态内部 classes 绑定到封闭 class.
的实例
注解是一种 Java 接口，与任何其他 class 一样，它们可以在 class 中定义。同样，它们可以声明为静态或非静态。这两种选择之间有什么区别，它们在使用代码时的使用方式有什么区别，是否存在使用其中一种有意义的场景？
示例：
public class AnnotationContainer {
public static @interface StaticAnnotation {}
public @interface NonstaticAnnotation {}
}
完全没有区别。嵌套接口始终是静态的。
这在 JLS Sec 8.5.1 中有描述（对于 类）：
A member interface is implicitly static (§9.1.1). It is permitted for the declaration of a member interface to redundantly specify the static modifier.
和JLS Sec 9.5（对于接口）：
A member type declaration in an interface is implicitly public and static. It is permitted to redundantly specify either or both of these modifiers.
进一步说明 它们完全相同，因为它们是一种特殊的接口声明，并且 "member interfaces" 无论如何都是隐式静态的：
An annotation type declaration specifies a new annotation type, a special kind of interface type. To distinguish an annotation type declaration from a normal interface declaration, the keyword interface is preceded by an at-sign (@).
JLS 10 8.5.1. Static Member Type Declarations :
A member interface is implicitly static (§9.1.1). It is permitted for the declaration of a member interface to redundantly specify the static modifier.
和JLS 10 9.1.1. Interface Modifiers
The modifier static pertains only to member interfaces (§8.5.1, §9.5), not to top level interfaces (§7.6).
旁注：有趣的是，这些章节没有使用第 9 章顶部定义的术语 "nested interface"，但它似乎是 "member interface" 的同义词：
A nested interface is any interface whose declaration occurs within the body of another class or interface.
