 *  Description: This application prints a table showing the total
 *   price paid for a $20,000 car if financing at various interest
 *   rates between 8 and 100 percent is assumed for a period of
 *   2 through 8 years.
 *
 *  The algorithm uses a nested for-loop to print the rows and columns
 *   of the table. Note the use of the java.text.NumberFormat class
 *   in the formatting of the numeric output.
