Upgrade Car To What Ever Possible

Implement the upgrade method in the Car class, which upgrades the features depending upon the money available. The upgrades available are AC (Rs. 21500), Leather Seats (Rs. 14400), Back Wipers (Rs. 6250) and Fog Lights (Rs. 3300). Whatever upgrades are possible have to be made. e.g., It’s not necessary that we have to upgrade AC before Leather Seats, and we can upgrade Fog Lights without AC or Leather Seats etc.,

Input (Available Amount) Output (Upgraded Car, Remaining Amount)
25000 AC and Fog Lights Installed
Remaining Amount = (25000 - 21500 - 3300) = 200
40000 AC, Leather Seats and Fog Lights Installed
Remaining Amount = (40000 - 21500 - 14400 - 3300) = 800
50500 AC, Leather Seats, Back Wipers and Fog Lights Installed
Remaining Amount = (50500 - 21500 - 14400 - 6250 - 3300) = 5050



class UpgradeCar
{
    public static void main(String s[])
    {
        Car sanjeev_santro = new Car("Sanjeev", "Santro");
        
        double availableAmount = 40000.0;
        double remainingAmount = sanjeev_santro.upgradeCar(availableAmount);
        
        System.out.println("Available Amount Before Upgrade : " + availableAmount);
        System.out.println("Installed AC : " + sanjeev_santro.hasAC);
        System.out.println("Installed Leather Seats : " + sanjeev_santro.hasLeatherSeats);
        System.out.println("Installed Back Wipers : " + sanjeev_santro.hasBackWipers);
        System.out.println("Installed Fog Lights : " + sanjeev_santro.hasFogLights);
        System.out.println("Amount After Upgrade : " + remainingAmount);

    }



}
class Car
{
    String ownerName;
    String model;

    Car(String ownerName, String model)
    {
        this.ownerName = ownerName;
        this.model = model;
    }
    
    boolean hasAC = false;
    boolean hasLeatherSeats = false;
    boolean hasBackWipers = false;
    boolean hasFogLights = false;

    double upgradeCar(double availableAmount)
    {
    }
}

User comments below. All of them might not be correct.

here we need to use the only if conditions..
*check the whether it is enough for upgrading Ac..
if(amount>=21500)
than Mak the AC true and reduce the 21500rs from the amount..amount-=21500;
* next check amount for Seats
If(amount>=14400) than Seats=true and amount-=14400;
* next check for Wipers
if(amount>=6250) than Wipers=true and amount-=6250;
*check for lights
if(amount>=3300) than Lights=true and amount-=3300
last return the amount

In Upgrade method we will check for each feature step by step if availableamount >=ac then availableamount-=ac and ac=true
similarly for each of four feature i.e.leather seats,backwipers and fog lights ..
At end available amount is returned with the help of return statement.
