Compile Error

[tberger1]

I am trying to right a program that calculates MPG of a car and then resets the odometer.

I set up a class for the odometer and then am trying to call in the different methods into main.

Here is the odometer class:

import java.util.Scanner;

public class Odometer
{
public int milesDriven;
public int milesPerGallon;
int first;
int last;
int gals;

public int calculateMPG()
{
return(last - first)/gals;
}

public void setOdometer()

{
milesDriven = 0;
}

public int calculateMiles()
{

return (first + last);
}

public void readMileage()
{
Scanner keyboard = new Scanner(System.in);

System.out.println("Enter the starting number of miles on odometer");
System.out.println("Enter the ending number of miles on odometer");
System.out.println("Enter gallons of gas pumped");
first = keyboard.nextInt();
last = keyboard.nextInt();
gals = keyboard.nextInt();
}
}

The main method is:

public class OdometerReading
{

public static void main(String[] args)
{
Odometer miles = new Odometer();
miles.readMileage();
System.out.println("The Miles are " + miles);

System.out.println("Miles per gallon is "+ miles.calculateMiles());

System.out.println("Miles per gallon is "+ miles.calculateMPG());

miles = setOdometer();
System.out.println("Current Miles "+ miles);
}
}

The compile error is at the setOdometer method it is:

OdometerReading.java:17: cannot find symbol
symbol : method setOdometer()
location: class OdometerReading
miles = setOdometer();
^
1 error

Tool completed with exit code 1

The files are saved in the same folder. I cannot figure out what I am missing here or what other problems I may be facing. Any and all help would be greatly appreciated.

Your definition of setOdometer states that it is a class method, therefore in your static main method should read

miles.setOdometer();
instead of miles=setodometer()
System.out.println("Current Miles "+ miles);
}

I also suspect you want

    public int calculateMiles()
    {

        return (last - first);
    }
