Chapter 3, Problem 9PC
Create an application that converts U.S. dollar amounts to pounds, euros, and yen. The following conversion factors are not accurate, but you can use them in your application:
1 dollar = 0.68 pound
1 dollar = 0.83 euro
1 dollar = 108.36 yen
In your code, declare named constants to represent the conversion factors for the different types of currency. For example, you might declare the conversion factor for yen as follows:
Const db1YEN_FACTOR As Double = 108.36
Use the named constants in the mathematical conversion statements. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. Use the following test data to determine whether the application is calculating properly:

- 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.
