You will write a racing report program using object-oriented programming with three classes:

ReportDriver, RaceReport, and Race. The main method of the program will be in the

class ReportDriver and will include a loop that allows you to enter in more than one race and

have reports written out for all the races you enter. (The user will enter one race then get a report

for that race. After that, the user will be asked whether they want to enter in another race and get

another report. This repeats until the user says they do not want to enter in any more races.)

Program Description

There are two major tasks in this assignment. Your first major task is to write a program that

collects three pieces of user input about a race and provides a summary of facts about the race.

Input will be via the keyboard and output (i. e., the summary of facts) will be via the display

(a. k.a., console window). The three pieces of user input will be the three individual race times

that correspond the first, second, and third top race finishers; your program will prompt the user to

enter these in via the keyboard. Note that you cannot assume these times will be in order; putting

them in order is one of the first things your program should do. Thus, your program will need to

do the following:

1. Prompt the user for three ints or doubles, which represent the times for the three racers.

2. Sort the three scores into ascending order (i. e., least to greatest).

(a) Remember, to swap two variables requires a third, temporary variable.

(b) See the Math class (documented in Savitch Ch. 5; see the index for the exact location

. . . this is good practice for looking things up) for methods that might help you (e. g.,

min and max). Note that these methods produce a return value.

(c) Output the sorted race scores in order.

3. Describe the overlap in times, if any exist. The options will be:

(a) All are tied for first.

(b) Some are tied for first.

(c) None are tied for first.

4. Do step (4) for the second and third place finishes.

5. Output the range of the race scores.

6. Output the average of the race scores.

There are, of course, many different ways of writing this program. However, if you decompose

your tasks into smaller chunks, attacking a larger program becomes more manageable. If you

mentally divided up the tasks before you, you might have decided on the following list of "work

items", "chunks", or "modules":

Data Input: Ask the user for three race scores (in no particular order).

Ordering Data: Order the race scores by first, second, and third place.

Data Analysis and Output:

– Determine how many racers tied for first, second or third place (i. e., how many overlap

times) and output result to console.

– Calculate the range of the race scores (i. e., the absolute value of the slowest minus the

fastest times) and output result to console.

2

– Calculate the average of the race times and output result to console.
