UML Class Diagram Concrete Product The classes and objects participating in the above UML class diagram are as follows: 1. Product This defines the interface of objects the factory method creates 2. Concrete reduct This is a class which implements the Product interface 3. Creator This is an abstract class and declares the factory method, which returns an object of type Product. This may also define a default implementation of the factory method that retums a default Concrete Product object. This may call the factory method to create il Proxluct ohject, 4. Concrete Creator This is a class wbich implements the Creator class and overrides the factory method to return an instance of a Concrete Product. Now let's understand this with a real world example strict class HealthPlan. You need to instantiate one of these classes, but you don't know which of them, it depends on the user. This is Assume you have three different healthcare plans which are considered here as classes HMO, PPO, Obamacare, all of them implement perfect woenaria for the l'alary Methexcl clesign patter. Each plan should have annual charge, deduction annount, plan type (HMO, PPO, Obamacare). Write il console application that asks the users the healthcare plan they want to apply in our put the information about the plin (alan type, annual charge, and clexluction amount).
