Everytime we use @Meal we are required to define mainCourse as it is a required element. It doesnt matter that the class has another @Meal annotation having mainCourse you still have to include it whenever you use the annotation @Meal

Hmm, I think it is DE since mainCourse variable need to be provided and I don't think it would accept null value
