CashRegister Class

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6’s Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:

The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.

Demonstrate the class in a program that asks the user for the quantity of items being purchased, and then displays the sale’s subtotal, amount of sales tax, and total.

Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing. Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons. Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
