 However, what if we only wanted to create books from the `FANTASY` genre? Passing the `FANTASY` parameter with each method call would be repetitive. Alternatively, we could define a new method specifically for creating `FANTASY` books, but it would be impractical to create a separate method for each genre. The solution is to use a curried function.
 
 ```java
-/**
- * Curried book builder/creator function.

 Unfortunately, the type signature of `BOOK_CREATOR` and `fantasyBookFunc` are difficult to read and understand. We can improve this by using the [builder pattern](https://java-design-patterns.com/patterns/builder/) and functional interfaces.
