How does Lombok annotation work?
Lombok acts as an annotation processor that “adds” code to your classes at compile time. Annotation processing is a feature added to the Java compiler at version 5. The idea is that users can put annotation processors (written by oneself, or via third-party dependencies, like Lombok) into the build classpath.
Is Lombok good or bad?
