| Ans. Annotations, a form of metadata, provide data about a program that is not part of the program itself. Annotations have no direct effect on the operation of the code they annotate. Annotations have a number of uses, among them: • Information for the compiler — Annotations can be used by the compiler to detect errors or suppress warnings. • Compile-time and deployment-time processing — Software tools can process annotation information to generate code, XML files, and so forth. • Runtime processing — Some annotations are available to be examined at runtime. | ||||
