calculating a fine and addtional fine java method error

Question

I have this problem I need to solve, I made a method to check if the parkingTime of a car is expired, here is the code

private boolean isParkingTimeExpired(ParkedCar car, ParkingMeter meter) {
    if(car.getNumberOfMinutesParked() > meter.getNumberOfPurchasedMinutes()) {
        return true;
    } else {
        return false;
    }     
}        

private double calculateFine(ParkedCar car, ParkingMeter meter) {
    double totalFine = 0;
    if(isParkingTimeExpired() == true) {
        totalFine = 20;
    }
}

I am told to make a method that will check if the parking time is expired and if so calculate the fine which is $20 per hour, and another $20 for every other additional hour. Now two things, when I try to call the method isParkingTimeExpired to check if time is expired it gives me an error saying method cannot be applied to given types, found no arguments, reason: actual and formal arguments differ in length. Why is this like that? I havent made much progress because I am lost trying to figure out the calculation and also why I cant call on the previous method. Any help is appreciated!

Answer 1

The issue is that you are calling isParkingTimeExpired() but not passing it any arguments in your second if statement.

In your method signature for isParkingTimeExpired it is expecting a ParkedCar object and ParkingMeter object (see below).

private boolean isParkingTimeExpired(ParkedCar car, ParkingMeter meter){

In order to call it correctly, you must pass it the required arguments like this: isParkingTimeExpired(car, meter);
