Therefore, these annotations do not affect the compiled program’s execution. They offer additional compiler information about the program but are not part of the program itself. Annotations are not just comments since they can affect how a program is processed by the compiler.Annotations aid in associating metadata to program components like methods, classes, variables, etc.Annotations do not affect the behaviour of a compiled program.Annotations always start with a For example: etc.These are some basics of annotations in Java: In Java, it is possible to build meta-annotations from existing ones. This enables the Java virtual machine to maintain annotations and read them through a reflection at run-time. ![]() Java annotations can also be included in and read from the Java compiler’s output Java class files. ![]() Developers may easily read the Java annotations directly from the source files, just like Javadoc tags. Various factors such as Java packages, variables, classes, parameters and methods can be annotated.
