Person and Customer Classes
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

Parent Class: Food
Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number).
Core Class Components
For the Food class, write:
the complete class header
the instance data variables
a constructor that sets the instance data variables based on parameters
getters and setters; use validity checking on the parameters where appropriate
a toString method that returns a text representation of a Food object that includes all three characteristics of the food
Class-Specific Method
Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage.
For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…

NewspaperSubscriber class- create an abstract class named NewspaperSubscriber with attributes to contain the subscriber’s street address and the subscription rate. Include get and set methods for both these attributes. The set method for the rate is abstract. The setAddress method must prompt the user to enter the subscriber’s address through the use of a dialog box. Create a constructor for the base class. Create a toString() method that concaternates and returns the subscriber’s street address and rate for display.
Create 3 child classes named SevenDaySubscriber, Weekday Subscriber, and Weekend Subscriber. Each child class has an additional attribute called subType, which is a String, that will store the type of newspaper subscription. Create a setType method that will set the type of subscriber as follows: “Seven Day”, “Weekday”, or“Weekend”. Create a setRate method for each child class that sets the rate as follows: a SevenDaysubscriber pays R18.00 per week for his newspapers, a…
