Please answer JAVA OOP question below: Consider the following relationship diagram between the Game and VideoGame data defintion classes. Game has a constructor that takes in two parameters, title (String) and cost (double). The VideoGame constructor has an additional parameter, genre (String). In Java, efficiently write the constructors needed within the Game class and VideoGame classes. Hint: Remember to think about the appropriate validation

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items. //Implementation Class public class ShoppingCart{ public static void main(String[] args){ final int MAX_ITEM = 50; Item cart = new Item[MAX_ITEM]; addItem(cart); // populate the item array printItem(cart); } } Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context? i) Polymorphism ii) Method Overloading iii) Method Overriding iv) Dynamic Binding v) Abstract Class Explain, using course terminology, how you would use any of the above concepts to model the given scenario.
