In this project we are going to create a class Sedan. A sedan is a four wheeled automobile with 4 doors. Each sedan can have a different gas tank that has a fixed capacity, and it can contain certain number of gallons of fuel. We will assume that each sedan can get a different fixed constant miles per gallon, and there is an EPA standard miles per gallon for all sedans that gets updates every year. The sedan also has a mileage. Right out of the factory, the sedan has a full tank of gas and zero mileage.

CLASS Sedan:

1) Create the following variables in the class, and determine the type, if static, if final

number of wheels

number of doors

epa mpg make this private

tank capacity

current fuel level make this private

mpg

mileage make this private

2) Create a default ctor for sedan

tank = 10

mpg = EPA mpg

full tank

zero mileage

3) Create a non default ctor for sedan

public Sedan(double ptankCapacity, double mpg)

a. print warning to if it does not meet the current EPA requirements

4) Define a toString method that prints basic stats of the sedan in the example below

public String toString()

5) Define a drive method

public double drive(double miles)

Drive either the specified miles or what the fuel allows

Deduct fuel according to miles driven

Return actual miles driven

6) Define a pump fuel method

public double pumpFuel(double gallons)

Pump with the specified gallons of what the fueld tank allows

Return actual fuel pumped

7) Overload a pump fuel method

public double pumpFuel()

Fill up tank

Return actual fuel pumped

8) setEPA

public static boolean setEPA(double newEPAmpg)

Sets the new EPA mpg

Return true if new EPA mpg is > 0; else do not set and return false

9) getEPA

a. get the current EPA mpg

10) getMileage

get the current mileage

note we cannot set the mileage directly because this is illegal!

11) getFuel

a. get the current fuel 12) equals

a. determine if two sedans are equal justify your answer

CLASS SedanTest:

1) Define an utility method to read a non-negative number from a scanner

static double readNNegDouble(String s, Scanner sc)

Print the prompt s

Read a double from scanner sc

Return if the double is > 0

Print error if no good and loop

2) Define a printMenu method

3) Define a main method

Set EPA mpg to 25

Create scanner

Create default sedan s1

Print it

Read in tank capacity and mpg for sedan 2 using the utility method

readNNegDouble

Create and print sedan s2

Do loop that operates on s2

i. printMenu

get input string

create switch statement to handle

1. 2. 3.

4. 5. 6.

h. print program

Sample Output:

drive a. print actual miles driven

pump fuel a. print actual gallons pumped

pump up a. print actual gallons pumped
