Question

Code to be written in JAVA please

In this assignment you will use a class Car to represent a car that travels to various destinations. Your car has a fuel economy rating of 32.3 miles per gallon. The gas tank holds 19.5 gallons. Your program will need to simulate two trips: 1) BC to Yosemite Valley, and 2) BC to Washington, D.C.. For each trip you will start with a full tank of gas. The output should look as follows.

Trip one: Bakersfield College to Dodger Stadium

Mileage: 204

Trip two: Bakersfield College to Washington, D.C.

Mileage: 2,686

The constructor will set the fuel efficiency rating to 32.3 mpg and the initial fuel level for each trip to zero.

Write a method addGas(), to fill the fuel tank.

Write a method getGasInTank(), returning the current amount of gasoline in the fuel tank.

Write a method named roadTrip() that simulates driving the car a given distance, reducing the

amount of gasoline in the fuel tank.

Let the user know they ran out of gas if they try to drive further than the fuel in the tank and the mileage allows. The output must show the mileage at which they would be where they run out of gas. Use int for mileage and discard any fractional values resulting from division.

All values must be hard-coded, do not use the Scanner class.

Save as a text file with the .java extension. Submit the .java files, do not submit the .class files. Be sure the class names match your file names, e.g. if your class is named Car the file name should be Car.java

Answer 1

public class Car {

    private double fuelEconomy;
    private double tankCapacity;

    public Car(double fuel) {
        fuelEconomy = fuel;
        tankCapacity = 0;

    }

    public void addGas(double gas) {
        System.out.println("Adding gas...");
        tankCapacity += gas;

    }


    public double getGasInTank() {
        return tankCapacity;
    }

    public void roadTrip(double distance) {

        double distanceTravelled = 0;
        System.out.println("Mileage: "+(int)(tankCapacity*fuelEconomy));
        System.out.println("Travelling a distance of "+distance+" miles");
        System.out.println("Gasoline Left: " + tankCapacity);

        while (tankCapacity > 0 || distanceTravelled >= distance) {

            if (tankCapacity > 5) {
                tankCapacity -= 5;
                distanceTravelled += 5 * fuelEconomy;
                if (distanceTravelled >= distance) {
                    System.out.println("You have reached your destination");
                    System.out.println("Gasoline Left: " + tankCapacity);
                    break;
                }
                System.out.println("Distance travelled : " + (int)(distanceTravelled));
                System.out.println("Tank Capacity: " + tankCapacity);
            } else {
                distanceTravelled += tankCapacity * fuelEconomy;

                if (distanceTravelled >= distance) {
                    System.out.println("You have reached your destination");
                    System.out.println("Gasoline Left: " + tankCapacity);
                    break;
                }
                tankCapacity = 0;
                System.out.println("Distance travelled : " +(int)(distanceTravelled));
                System.out.println("Tank Capacity: " + tankCapacity);
                System.out.println("You need to refuel the tank");

            }


        }

    }

    public static void main(String[] args) {

        System.out.println("Trip one: Bakersfield College to Dodger Stadium");
        Car tripOne = new Car(32.23);
        tripOne.addGas(40);
        tripOne.roadTrip(500);
        System.out.println("Trip two: Bakersfield College to Washington, D.C.");
        Car tripTwo = new Car(32.23);
        tripTwo.addGas(50);
        tripTwo.roadTrip(19*32);


    }
