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:

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

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

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

o 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:

o The renter’s gender and age
o The renter’s rate class
o The 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:

o Calculating age

o Determining the rate class

o Displaying the results.

EXAMPLE RUN:

Thank you.
The female renter is 30 years old.
The rate class is: Best rate - $40.00 per day or $200.00 per week.
I?

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.

HINTS:

? Be sure to test for ‘borderline’ cases. EXTRA CREDIT:

If you attempt the extra credit portion of the assignment, be sure to include a comment to the grader.

5 points: Use the java.util.Date class to get the current date. ? DEPRECATED!!!
Note: The ‘Date’ class has been replaced with a more capable utility – the ‘Calendar’ class. Use

the Calendar class instead.
You must figure out how to use this Java library API yourself.

Special Note: This assignment will provide you with a pre-written main() method. You must make your code conform to the pre-written main method:

// Rental rates assignment
// Pre-set main for testing (see DEBUG constant)
// Required methods to be added: calcAge(...), calcRateClass(...) and displayResult(...) // Also, insert code into main as indicated.

Explanation / Answer

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.
