1. Please broadly explain what the code in the driver class does for both of them. 2. What do you think about the two driver class file? Which one was better? Please make your answer concise  public class PersonFoodListDriver { public static void main(String[] args) { PersonFoodList myList = new PersonFoodList(); myList.addNode(new PersonFoodNode(new PersonFood("Emilia","Lemon Pudding Cake")));
