This is another awesome Java library you should learn in 2023 as it makes working with Java really fun by removing the boilerplate coding. For example, you can declare your Java class with just fields with getter and setter and it looks really clean as shown in this Lombok example.

You can instruct Lombok to create common methods like equals and hashcode, toString, getter, and setters as well you can also put assertions like NonNull for robust coding. All that can be done by adding just a few annotations like @ToString, @EQualsAndHashCode, @NonNull, etc.

You can also create builder and constructor using Lombok by using @Builder annotation and then there is @Data annotation which automatically applies common annotations ot make your code even cleaner.

Here is a class that is declared using Lombok, you can see that its much cleaner than traditional POJO (Plain Old Java Object]
