CIS $214,$ Week $3,$ Fun with OOP and Bicycles

As your first chance to explore the wonderful world of object$-$oriented programming, I

thought this would be a good time to play with a bicycle. Everyone likes bicycles $-$

except Calvin of course.

This week you are going to create a Bicycle class that can be used to create a digital

bicycle.

We$$re going to strip off all the non$-$essential components $($brakes$,$ for example$)$ and

focus on the things that make the bicycle go $($faster$).$ If you$$re wondering where the idea

for this project came from, in grade school I was the smallest, skinniest, slowest kid in

my class. But I was the only one who owned a three$-$speed Schwinn and you let me

crank the pedals three times and no one could catch me$.$ So we$$re going to build a

bicycle with a focus on speed.

Your Bicycle class will have the following attributes $($and no more$).$

Gears $(1$ through $3)$

Cadence $(1$ rpm through $100$ rpm$).$ In cycling, cadence is the rate at which a cyclist is

turning the pedals.

Speed $($in miles per hour$)$

Your Bicycle class will have the following behaviors $($and no more$).$

The rider will be able to enter gear settings between $1$ and $3.$

The rider will be able to enter a cadence between $1$ and $100.$

Given a gear setting and cadence, the Bicycle will be able to calculate its speed in miles

per hour and output that result.

Rules for calculating MPH in various gear settings

First gear $$ MPH $=$ cadence $/13$

Second gear $$ MPH $=$ cadence $/7$

Third gear $$ MPH $=$ cadence $/3$

You will create a Bicycle class $($Bicycle$.$java$)$ that follows the specification above. Then

you will create an application to test the Bicycle class $($BicycleTest$.$java$).$ The application

will instantiate a Bicycle object, then permit the $$rider$$ to enter a cadence and gear

setting. The rider will be prompted to enter a cadence between $1$ and $100$ and a gear

setting between $1$ and $3.$ Once the cadence and gear setting have been entered, the

application will output the bicycle$$s speed.

Class members will be declared public and private as appropriate.
