You must display your code and run the projects to demonstrate the output.

Submit each project individually..

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 program.

Retail Price Calculator

Create a GUI application where the user enters the wholesale cost of an item and its markup percentage into text fields. (For example, if an item’s wholesale cost is \$5 and its markup percentage is 100 percent, then its retail price is \$10.) The application should have a button that displays the item’s retail price when clicked.

Theater Revenue

A movie theater only keeps a percentage of the revenue earned from ticket sales. The remainder goes to the movie company. Create a GUI application that allows the user to enter the following data into text fields:

# Number of adult tickets sold

# Price per child ticket

# Number of child tickets sold

The application should calculate and display the following data for one night’s box office business at a theater:

·          Gross revenue for adult tickets sold: This is the amount of money taken in for all adult tickets sold.

·          Net revenue for adult tickets sold: This is the amount of money from adult ticket sales left over after the payment to the movie company has been deducted.

·          Gross revenue for child tickets sold: This is the amount of money taken in for all child tickets sold.

·          Net revenue for child tickets sold: This is the amount of money from child ticket sales left over after the payment to the movie company has been deducted.

·          Total gross revenue: This is the sum of gross revenue for adult and child tickets sold.

·          Total net revenue: This is the sum of net revenue for adult and child tickets sold.

Assume the theater keeps 20 percent of its box office receipts. Use a constant in your code to represent this percentage.
