Question

Develop a Java application that provides program output in a logical manner and incorporates appropriate data types. Similar to zyBooks examples in Chapter 2, your program should prompt a user to enter a car brand, model, year, starting odometer reading, ending odometer reading, and gallons used. The output should include this information along with the estimated miles per gallon consumed by the vehicle in the format MPG: your calculation. Print each on separate lines with the appropriate labels (example, MPG: 25) Submit your source code and screenshots of the application executing with output in a single document.

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new java program with name "Main.java" is created, which contains following code.

Main.java :

import java.util.*;//import package
public class Main //Java class
{ //entry point of program , main method
   public static void main(String[] args) {
   //creating object of scanner class
   Scanner input=new Scanner(System.in);
   //asking user to enter car brand
       System.out.print("Enter Car Brand : ");
       String carBrand=input.nextLine();//reading carBrand
       //asking user to enter car model
       System.out.print("Enter Car model : ");
       String model=input.nextLine();//reading model
       //asking user to enter car year
       System.out.print("Enter Car year : ");
       int year=input.nextInt();//reading year
       //asking user to enter starting odometer reading
       System.out.print("Enter Car starting odometer reading : ");
       double startingOdometerReading=input.nextDouble();//reading starting odometer reading
//asking user to enter ending odometer reading
       System.out.print("Enter Car ending odometer reading : ");
       double endingOdometerReading=input.nextDouble();//reading ending odometer reading
       //asking user to enter gallons used
       System.out.print("Enter gallons used : ");
       double gallons=input.nextDouble();//reading gallons used
       //calculate MPG
       double MPG=(endingOdometerReading-startingOdometerReading)/gallons;
       //print car details
       System.out.println("---------CAR DETAILS----------------");
       System.out.println("Car Brand : "+carBrand);//print car brand
       System.out.println("Car Model : "+model);//print car model
       System.out.println("Car Year : "+year);//print car year
       System.out.println("Car starting odometer reading : "+startingOdometerReading);//print starting odometer reading
       System.out.println("Car ending odometer reading : "+endingOdometerReading);//print ending odometer reading
       System.out.println("Gallons Used : "+gallons);//print gallons
       System.out.println("MPG: "+MPG);//print MPG
   }
}

======================================================

Output : Compile and Run above program to get the screen as shown below

Screen 1 :Main.java
