c) Suppose we have a class User which has a constructor with the header User (String name, Account account) where name gives the name of a person who is to be the User, and account gives the Account, which belongs to the User. Write a class UserFactory that creates User objects, but if a User object with the same name and same account already exists, it returns that User object rather than a new User object. The class User has a method getName() that returns the name of the User and getAccount() which returns the Account of the User. This is an example of the Factory Object design pattern.
