Design a class named Person with fields for holding a person's name, address, and telephone number (all as Strings ). Write a constructor that initializes all of these values, and mutator and accessor methods for every field. Next, design a class named Customer, which inherits from the Person class. The Customer class should have a String field for the customer number and a boolean field indicating whether the customer wishes to be on a mailing list. Write a constructor that initializes these values and the appropriate mutator and accessor methods for the class 's fields. Demonstrate the Customer class in a program that prompts the user to enter values for the customer's name , address, phone number, and customer number, and then asks the user whether or not the customer wants to receive mail. Use this information to create a customer object and then print its information. Put all of your classes in the same file. To do this, do not declare them public. Instead, simply write: class Person { ... } class Customer { ... }
