我在我的驱动程序类中不断出错，但我不确定我做错了什么

Question

This is a code for a foundations class that I'm working on currently. I keep getting an error, but I'm not sure what I've done incorrectly. Any help would be greatly appreciated. Thanks!

package miles;

public class Miles {

    private int miles;
    private int gas;
    public static int mpg;

    public void setMiles(int miles) {

        this.miles = miles;

    }

    public void setGas(int gas){

        this.gas = gas;

    }


    public int getMpg(){
        mpg = miles/gas;
        return mpg;
    }


}

package miles;
import java.util.Scanner;

public class MilesDriver {


    public static void main(String [] args) {


        Miles gas =  new Miles();

        Scanner input = new Scanner(System.in);

        System.out.println("Enter Miles: ");
        int setGas = input.nextInt();

        System.out.println("Enter Gas: ");
        int setMiles = input.nextInt();

        System.out.printf("MPG:  %n%s%n",  gas.getMpg() );


    }
}

You actually forgot to set the values of your object :

    System.out.println("Enter Miles: ");
    int setMiles = input.nextInt();
    gas.setMiles(setMiles);

    System.out.println("Enter Gas: ");
    int setGas = input.nextInt();
    gas.setGas(setGas);

Try not to give a variables name the same name as a method of your object. You'll end confusing yourself and get stuck.
