I have a method in a Helper class that is as follows:

public int addReservation(Reservation aReservation)

{

int i = 0;

int returnCode=1;

//add code here:

if(reservationList.size() > 0)

{

while(returnCode == 1)

{

if(aReservation.getReservationDateTime().getTime() < reservationList.get(i).getReservationDateTime().getTime())

{

reservationList.add(i, aReservation);

returnCode = 0;

}

}

}

else

{

reservationList.add(aReservation);

returnCode = 0;

}

return returnCode;

}

reservationList is a linkedList. Whenever I try to add a reservation in the program, it appears that the reservation is not found. How can I resolve this issue?
