Thread: Calculation error...very New to Java..please be kind.

Hello, I am doing the famous Parking ticket simulator. I have the whole thing compiling and it works! however, I am out on my calculations. My vehicle is parked for 125 mins, and I paid for 60 minutes. I am being fined for 65 minutes of illegal parking.

The first hour is $25 base fine, and after 120 minutes, $10 should be added. I have something wrong here, as when I run the code, it is adding $25 for the base rate, $20 for time parked. It is either looking at the total time parked as illegal, and charging me as such, or it is charging me $35 (25 for base fine + hourly fine)for the first hour of illegal parking, and $10 for the part hour...Please help, as I have gone through this again and again.

Here is the code: (just the class that has the calculations, I can put the whole thing up, but it is quite large.)

import java.text.DecimalFormat;
 
public class ParkingTicket
{
    private ParkedCar car;
    private PoliceOfficer officer;
    private double fine;
    private int minutes;
    final double BASE_FINE = 25.0;
    final double HOURLY_FINE = 10.0;
 
    public ParkingTicket(ParkedCar car, PoliceOfficer officer, int minutes) 
    {
        this.car = car;
        this.officer = officer;
        this.minutes = minutes;
    }
 
    public ParkingTicket(ParkingTicket ticket2)
    {
        car = ticket2.car;
        officer = ticket2.officer;
        fine = ticket2.fine;
        minutes = ticket2.minutes;
    }
 
    public void calculateFine()
    {
        if(car.getMinutesParked() >= 60)
        {
            if(car.getMinutesParked() - ParkingMeter.getMinutesPurchased() <= 60)
            {   fine = BASE_FINE;
            }
            else
            {
                fine = BASE_FINE + (HOURLY_FINE * ((car.getMinutesParked() - ParkingMeter.getMinutesPurchased()) /60));
            }
        }
    }
 
    DecimalFormat decimalformat = new DecimalFormat("#0.00");
 
    public double getFine()
    {
        return fine;
    }
 
    public String toString()
    {
        String string = car + "\n" + officer + "\n" + "The fine is: \n $" +  decimalformat.format(fine) ;
        return string;
    } 
}

First off you should indent your code and use code tags.
What is happening at:

if(car.getMinutesParked() >= 60)

Should you not have some type of calculation here?

Sorry about the formatting...it got lost in the c&p..

As far as that line..

it is stating that if the car is parked for longer than 60 minutes, then issue a ticket.

The .getMinutes Parked is from the Parked Car class.

public int getMinutesParked()
{
return minutesParked;
}
