Write a class named SpecialCustomer, which inherits from the Customer class. The SpecialCustomer class should have int fields for the amount of the customer's purchases and the customer's discount level.

A retail store has a special customer plan where customers can earn discounts on all their purchases. The amount of a customer's discount is determined by the amount of the customer's cumulative purchases in the store, as follows:

When a special customer spends $500, they get 5% discount on all future purchases.

When a special customer spends $1,000, they get 8% discount on all future purchases.

When a special customer spends $1,500, they get a 10% discount on all future purchases

When a special customer spends $2,000, they get a 15% discount on all future purchases

Write a constructor that initializes the fields of the SpecialCustomer class and define accessor and mutator methods. Use super keyword in the subclass constructor, if needed.

Demonstrate the class by defining a CustomerDemo class that prompts the user to input the customer's name, address, phone number, customer number, whether they want to receive mail, and the amount they've spent, and then uses that information to create a SpecialCustomer object and print its information (for printing the information, you may need toString() method).

Create a UML diagram that shows all three classes and the inheritance relationship between these classes.
