 You can dramatically simplify the code for a DTO by using https://projectlombok.org[Project Lombok], which provides an `@Value` annotation (not to be confused with Spring's `@Value` annotation shown in the earlier interface examples).
 If you use Project Lombok's `@Value` annotation, the sample DTO shown earlier would become the following:
 
-[source, java]
+[source,java]

 @Value
 class NamesOnly {
 	String firstname, lastname;
