Java.lang.annotation Package
The `java.lang.annotation` package in Java provides a framework for defining and using annotations, which are a form of metadata that can be added to Java source code elements such as classes, methods, fields, and parameters. Annotations provide additional information about the code and can be used by tools, frameworks, and runtime environments to modify the behavior of the code or to generate auxiliary code. Key components of the `java.lang.annotation` package include **Annotation**, which is the root interface for all annotations, and **AnnotationTypeMismatchException**, which is an exception thrown when a program attempts to access an annotation element whose type does not match the expected type. Additionally, the package includes meta-annotations such as **@Retention** and **@Target** for specifying the retention policy and target elements of custom annotations, respectively. Annotations are widely used in Java for various purposes such as documentation, code analysis, configuration, and runtime processing, making the `java.lang.annotation` package an essential part of the Java language and ecosystem.
Provides Java library support for the Java programming language's Java annotation facility.
