If there are final-modified fields and no final-modified fields are initialized, simple use of the @NoArgsConstructor annotation will prompt compilation errors. Setting callSuper to true when you do not extend a class (just any java.lang.Object class) prompts compilation errors because Lombok converts the generated equals() method and hashCode() implementation into inheritance from Object: only the same Object objects are equal to each other and have the same hashCode. In this tutorial, you will learn how Lombok helps us to create getter, setters, toString, constructor, equals, hashCode methods, etc automatically. The @ToString annotation generates an implementation for the toString () method where the class name, along with each field in order, separated by commas, is printed. @ NoArgsConstructor will generate a parametric constructor. For example, in the following example, only fields decorated with @NonNull and final add constructors. For this purpose, use the @ ToString.Include tagging method.
