How do you use Lombok?

Lombok is a Java library that simplifies Java code writing by automatically generating common methods such as getters, setters, and constructors for Java classes. Here is how you can use Lombok:

1. Add the Lombok dependency to the project build file (such as pom.xml) or manually download the Lombok library and add it to the project.
2. Add annotations like @Data, @Getter, @Setter to the Java class where Lombok is needed. The functions of different annotations are as follows:
3. @Data annotation generates getter, setter, equals, hashCode, and toString methods for a class.
4. @Getter and @Setter: Automatically generate getter and setter methods for a class.
5. @NoArgsConstructor: Generates a constructor with no arguments.
6. @AllArgsConstructor: generate a constructor that includes all parameters.
7. @RequiredArgsConstructor: This generates a constructor that includes fields marked as final, as well as fields annotated with @NonNull.
8. @ToString: Creates a toString method.
9. @EqualsAndHashCode: Automatically generates equals and hashCode methods.
10. @Builder: Generate a constructor for the Builder pattern.
11. Generated methods like getters, created using Lombok, can be used directly in the code.

It is important to note that when using Lombok, the corresponding plugin needs to be installed, such as in IntelliJ IDEA. Additionally, while Lombok can reduce the amount of code and increase development efficiency, it may also make the code difficult to read and understand, so it is important to weigh the advantages and disadvantages when using it.
