Question

Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).

Ex: If the input is:

2011

18000

2018

where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is:

Car's information:

   Model year: 2011

   Purchase price: 18000

   Current value: 5770

Note: printInfo() should use three spaces for indentation

 

CarValue.java

import java.util.Scanner;
import java.lang.Math;

public class CarValue {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);

Car myCar = new Car();

int userYear = scnr.nextInt();
int userPrice = scnr.nextInt();
int userCurrentYear = scnr.nextInt();

myCar.setModelYear(userYear);
myCar.setPurchasePrice(userPrice);
myCar.calcCurrentValue(userCurrentYear);

myCar.printInfo();
}
}

 

Car.Java

public class Car {
private int modelYear;
// TODO: Declare purchasePrice field (int)

private int currentValue;

public void setModelYear(int userYear){
modelYear = userYear;
}

public int getModelYear() {
return modelYear;
}

// TODO: Define setPurchasePrice() method

// TODO: Define getPurchasePrice() method


public void calcCurrentValue(int currentYear) {
double depreciationRate = 0.15;
int carAge = currentYear - modelYear;

// Car depreciation formula
currentValue = (int)
Math.round(purchasePrice * Math.pow((1 - depreciationRate), carAge));
}

// TODO: Define printInfo() method to output modelYear, purchasePrice, and currentValue

}
