本文整理了Java中java.lang.annotation.Annotation类的一些代码示例，展示了Annotation类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Annotation类的具体详情如下：
包路径：java.lang.annotation.Annotation
类名称：Annotation

Annotation介绍

[英]Defines the interface implemented by all annotations. Note that the interface itself is not an annotation, and neither is an interface that simply extends this one. Only the compiler is able to create proper annotation types.
[中]定义由所有注释实现的接口。请注意，接口本身不是注释，也不是简单扩展此注释的接口。只有编译器才能创建正确的注释类型。
