Write a Java program that helps a person decide whether to buy a hybrid car. 
Your program’s inputs should be:
 • The cost of a new car
 • The estimated miles driven per year
 • The estimated gas price
 • The efficiency in miles per gallon
 • The estimated re-sale value after 5 years
Compute the total cost of owning the car for five years. 
(For simplicity, we will not take the cost of financing into account.) 
Obtain realistic prices for a new and used hybrid and a comparable car from the Web.
Run your program twice, using today’s gas price and 15,000 miles per year.


Code:

import java.util.Scanner;

public class Main
{
        public static void main(String[] args) {
            
            Scanner input = new Scanner(System.in);
            double car_cost;
            double miles_driven;
            double gas_price;
            double fuel_efficiency;
            double resale_value;
            double cost_to_own;
            
            System.out.print("Car cost: ");
            car_cost = input.nextDouble();
            
            System.out.print("Miles driven: ");
            miles_driven = input.nextDouble();
            
            System.out.print("Gas price: ");
            gas_price = input.nextDouble();
            
            System.out.print("Fuel Efficiency: ");
            fuel_efficiency = input.nextDouble();
            
            System.out.print("Re-sale value:  ");
            resale_value = input.nextDouble();
            
            input.close();
            
            cost_to_own = car_cost * (fuel_efficiency * miles_driven * gas_price);
            
            System.out.printf("Cost to own: %.2f", cost_to_own);
            System.out.println("Cost after re-sale: " + (car_cost - resale_value));
    }
}
