Question

Write a program called RentalRate.java which reads in

a date of birth, today’s date and a male/female

designation from the user, and will then determine the

basic daily and weekly rates for rental of an economy

class car.

Rental rate classes are:

Best rate (male drivers, age 33–65 and female drivers, age 30-62)--$40.00per day, $200.00 per week

Risk rate 1 (female drivers, age 25–29)–Best rate plus $10.00 per day or best rate plus $55.00 per week.

Risk rate 2 (male drivers, age 25–32)–Risk rate 1 plus $7.00 per day or risk rate1 plus $30.00 per week.

Risk rate 3 (male driver, age 66+ and female drivers, age 63+)–Best rate plus$2.00 for each year over age 65 (male) or 62 (female), per day or best rate plus

$5.00 for each year over age 65 (male) or 62 (female), per week.

PROGRAM PARTICULARS:

?When the program starts, ask the user for the renter’s gender–m or f.

?If not attempting extra credit, ask the user for today’s date

?Then ask the user for the renter’s month, day and year of birth (also see extra credit.)

?The program will determine the renter’s age and display:

oThe renter’s gender and age

oThe renter’s rate class

oThe renter’s rate per day and per week.

You may assume that user input provided will be valid for the base assignment (see Extra

Credit below.) Dates will be entered as individual integer values.

?Your program should be modular. Create separate methods for:

oCalculating age

oDetermining the rate class

oDisplaying the results.

EXAMPLE RUN:

Welcome to the car renter's rate finder.

Please enter the renter’s gender (m/f):

m

Please enter today's date (mm dd yyyy):

10 4 2011

Please enter the renter’s date of birth (mm dd yyyy):

1 22 1990

Thank you.

The male renter is 21 years old.

The rate class is: Sorry, the renter is not 25 years of age or

older.

Note: If you attempt the extra credit, your sample run will differ from the above

listing as you will not need to ask for today’s date, and invalid data will cause an error message to be displayed.

Note: The ‘Date’ class has been replaced with a more capable utility–the ‘Calendar’ class. Use the Calendar class instead.

Answer 1

Given below is the code for the question. The extra credit part is done. Also you can change the DEBUG = true to test the various test cases. If DEBUG = false, then it will prompt for data from user. It will not prompt for current date since extra credit part is implemented and the program gets the current date from Calendar.
