Uses of Interface
java.lang.annotation.Annotation
Package
Description
Contains classes related to developing beans -- components based on
the JavaBeans architecture.
Provides for system input and output through data streams,
serialization and the file system.
Provides classes that are fundamental to the design of the Java
programming language.
Provides library support for the Java programming language
annotation facility.
Provides classes and interfaces for obtaining reflective information about
classes and objects.
Facilities for declaring annotation processors and for
allowing annotation processors to communicate with an annotation processing
tool environment.
Types and hierarchies of packages comprising a Java language model, a model of the declarations and types of the Java
programming language.
Interfaces used to model elements of the Java programming language.
Interfaces used to model Java programming language types.
Provides the core classes for the Java Management Extensions.
Provides a set of "lightweight" (all-Java language) components
that, to the maximum degree possible, work the same on all platforms.
