What is the purpose of Lombok in Java?

Lombok exists to cut down the sheer amount of repetitive, mechanical code that plain Java classes typically require — particularly simple data-holding classes (often called POJOs) that need getters, setters, constructors, and standard Object method overrides just to function correctly with frameworks, collections, and equality checks.

Without Lombok, a class with five fields might need 40-plus lines of generated-looking code just for getters, setters, and a proper equals/hashCode/toString. With Lombok, a handful of annotations replace all of that, letting the class definition focus on what data it actually holds rather than the mechanical methods every field needs.

@Getter @Setter @ToString @EqualsAndHashCode
public class Product {
    private String id;
    private String name;
    private double price;
}
