Thread: trouble finding object

public class PoliceOfficer
{
String officerName;
double badgeNumber;
ParkedCar carInfo;
ParkingMeter meter;
double timeParked;
double timePurchased;
 
 
//constructor to get name and badge number
PoliceOfficer(String name,double number,ParkedCar car,ParkingMeter met)
{
officerName=name;
badgeNumber=number;
carInfo=car;
meter=met;
 
}
 
 
public ParkingTicket ticketTest()
{
if(carInfo.getMinutesParked()>meter.getMinutesPurchased())
{
ParkingTicket ticket=new ParkingTicket(carInfo.getMinutesParked(),meter.getMinutesPurchased(),carInfo);
}
return ticket;
}
 
 
public String toString()
     { 
         String str=" "+ticketTest()+" the officers name and badge number are "+officerName+" and "+badgeNumber;
         return str;
      }

public class ParkingTicket
{
private double minutesParked;
private double minutesPurchased;
double fineAmount=25;
ParkedCar carInfo;
//constructor to get car and meter data
ParkingTicket(double parked, double purchased,ParkedCar car)
{
minutesParked=parked;
minutesPurchased=purchased;
carInfo=car;
}
 
//method to return the fine amount
public double getFineAmount()
{
for(double i=minutesParked;i<minutesPurchased;i++)
{
fineAmount=fineAmount+10;
}
return fineAmount;
}
 
public String toString()
      {
         String str=carInfo+" your fine amount is "+getFineAmount();
         return str;
      }
 
 
 
}

My error message tells me that in the police officer class it can not find ticket where it says "return ticket" inside the ticketTest method
thanks
