Question

This program gets the number of miles traveled and the gallons of gas used, and prints out MPG. You are to complete the method AND add a loop to main so that you continually ask for input and calculate MPG until the user gives you a zero for the miles traveled. NOTE: Do not ask for gallons of gas or call the method if miles is zero. I suggest you FIRST write the method and then worry about the loop.

import java.util.Scanner;

public class Number1 {

  
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
//get the miles traveled
System.out.println("Enter the number of miles traveled, 0 to stop");
double miles=keyboard.nextDouble();

System.out.println("Enter the amount of gas consumed");
//get the gas used
double gas=keyboard.nextDouble();
//output MPG
  
double mpg=MilesPerGallon(miles, gas);
System.out.println("Gas usage was " + mpg + " MPG");

}
public static double MilesPerGallon(double m, double g)
{ //calculates mpg by dividing miles by gallons
//and returns the result
  
}

}

Explanation / Answer

Number1.java

import java.util.Scanner;

public class Number1 {

public static void main(String[] args) {

Scanner keyboard = new Scanner(System.in);

//get the miles traveled

System.out.println("Enter the number of miles traveled, 0 to stop");

double miles=keyboard.nextDouble();

while(miles!=0)

{

System.out.println("Enter the amount of gas consumed");

//get the gas used

double gas=keyboard.nextDouble();

//output MPG

double mpg=MilesPerGallon(miles, gas);

System.out.println("Gas usage was " + mpg + " MPG");

System.out.println(" Enter the number of miles traveled, 0 to stop");

miles=keyboard.nextDouble();

}

}

public static double MilesPerGallon(double m, double g)

{ //calculates mpg by dividing miles by gallons

//and returns the result

return m/g;

}

}

Output:

Enter the number of miles traveled, 0 to stop
500
Enter the amount of gas consumed
5
Gas usage was 100.0 MPG

Enter the number of miles traveled, 0 to stop
450
Enter the amount of gas consumed
6
Gas usage was 75.0 MPG

Enter the number of miles traveled, 0 to stop
0
