Annotation：In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code.[1]
Classes, methods, variables, parameters and packages may be annotated. Like Javadoc tags, Java annotations can be read from source files. Unlike Javadoc tags, Java annotations can also be embedded in and read from class files generated by the compiler. This allows annotations to be retained by Java VM at run-time and read via reflection.[2]
It is possible to create meta-annotations out of the existing ones in Java.[3]
