Really interesting idea of mimicking Lambok. Will try this one.

I solved this a bit differently with property objects in Codename One. The core idea was to eliminate getters/setters and use general purpose property objects: codenameone.com/blog/properties-are-amazing.html

So the code would be:

public class Book implements PropertyBusinessObject {
    public final Property<Book, String> isbn = new Property<>("isbn"); 
    public final Property<Book, String> title = new Property<>("title"); 
    public final Property<Book, String> author = new Property<>("author"); 
}

Notice I need the string names since code in Codename One is often obfuscated and I want runtime information.

Then we can create a book with a factory like this:

Book b = new Book()
    .author.set("Shai Almog")
    .title.set("Create an Uber Clone in 7 Days");
