About this document

Understanding Java Annotations in Programming is a document available to read on EtoBox.

Java annotations allow metadata to be added to Java source code and made available at runtime. Annotations can be placed on classes, methods, fields, parameters, local variables, and packages. Unlike documentation tags, annotations are accessible to programmers during program execution using reflection. The Java EE 5 platform uses annotations for tasks like defining web services, developing EJB applications, and mapping classes to XML, databases, and methods to operations.
