What are the differences between @Value and @Data annotations in the Lombok library?

The @Data annotation in Lombok generates for a class:

• getters and setters for all fields,
• equals(), hashCode(),
• toString() method,
• default constructor,
• and RequiredArgsConstructor (constructor for final fields).

The @Value annotation makes a class immutable:

• all fields are private and final,
• generates only getters (no setters),
• generates equals(), hashCode(), toString(),
• generates a constructor with all fields,
• the class is marked as final.

In summary:

• @Data — for mutable classes with a full set of methods.
• @Value — for immutable classes where fields cannot be changed after creation.

Example:

@Data
class User {
    private String name;
    private int age;
}

@Value
class ImmutableUser {
    String name;
    int age;
}
