Description: An annotation class in Kotlin is a special type of class used to define annotations, which are metadata that can be applied to classes, functions, properties, and other code elements. These annotations allow adding additional information that can be utilized by the compiler or at runtime. In Kotlin, annotations are declared using the ‘annotation class’ keyword and can contain properties that can be initialized. Annotations are particularly useful for providing information about the behavior of the code, such as data serialization, dependency injection, or parameter validation. Additionally, annotations can be processed by build tools or third-party libraries, allowing for greater flexibility and extensibility in application development. In summary, annotation classes in Kotlin are a powerful tool for enriching code with metadata that facilitates programming and enhances interoperability with other libraries and frameworks.
