Java Lombok Purpose Explained: Auto-Generate Code

Java Lombok serves to automatically generate code through annotations, reducing repetitive work for developers and improving code readability and maintainability. In particular, Lombok can assist in generating the following code:

1. Getter and Setter methods: By using the @Getter and @Setter annotations, Getter and Setter methods for properties can be automatically generated, reducing the need to manually write out this repetitive code.
2. Construction methods: Using the annotations @NoArgsConstructor, @AllArgsConstructor, and @RequiredArgsConstructor can automatically generate a no-argument constructor, a constructor with all arguments, and a constructor with some arguments.
3. toString method: By using the @ToString annotation, the toString method can be automatically generated, making it convenient to print the content of the object.
4. equals and hashCode methods: Using the @EqualsAndHashCode annotation can automatically generate equals and hashCode methods, making it easy to compare objects and calculate their hash codes.
5. Logging: Using the @Slf4j annotation can automatically generate logging objects, making it convenient to use logging functions in the code.

By using Lombok, developers can significantly reduce the amount of redundant code they need to write, improving the efficiency and quality of their code.
