@Data is a convenient shortcut annotation that bundles the features of @ToString , @EqualsAndHashCode , @Getter / @Setter and @RequiredArgsConstructor together: In other words, @Data generates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields,Click to see full answer. Just so, what is the meaning of annotation in Java?In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. Classes, methods, variables, parameters and Java packages may be annotated. This allows annotations to be retained by the Java virtual machine at run-time and read via reflection.Beside above, what does Lombok @data do? Lombok is used to reduce boilerplate code for model/data objects, e.g., it can generate getters and setters for those object automatically by using Lombok annotations. The easiest way is to use the @Data annotation. Then, what is the use of annotations in Java? Annotations in Java, provide a mean to describe classes, fields and methods. Essentially, they are a form of metadata added to a Java source file, they can’t affect the semantics of a program directly. However, annotations can be read at run-time using Reflection & this process is known as Introspection.What is annotation in Java and how it works?Annotations in Java. Annotations are used to provide supplement information about a program. Annotations start with ‘@’. Annotations do not change action of a compiled program. Annotations help to associate metadata (information) to the program elements i.e. instance variables, constructors, methods, classes, etc.
