Design a class named person with fields for holding a person's name, address, and telephone number. write one or more constructors and the appropriate mutator and accessor methods for the class's fields.
next, design a class named customer, which extends the person class. the customer class should have a field for a customer number and a boolean field indicating whether the customer wishes to be on a mailing list. write one or more constructors and the appropriate mutator and accessor methods for the class's fields. demonstrate an object of the customer class in a simple program.
(instructor request) for the demo, write a main that creates 3 customers and prints out their information. make up some names, addresses, phone numbers, etc. so no user input is required.
