Some methods are displaying the result on the server instead on the client.

Question

When I test (form SeatReservationClient class) the method sri.showReservations() located in SeatReservationClient class the results are being displayed on the server side instead on the client but the method sri.numReservations() is displaying the result as i want it i.e. on the client. Please can anyone help me (as always on this forum) find a solution to this problem and display the results correctly?
I have 5 classes:
Interface
public interface SeatReservationInterface extends java.rmi.Remote
     public boolean isReserved(int row, int seat) throws java.rmi.RemoteException;
     public boolean reserve(int row, int seat) throws java.rmi.RemoteException;
     public boolean cancel(int row, int seat) throws java.rmi.RemoteException;
     public int numReservations() throws java.rmi.RemoteException;
public void showReservations() throws java.rmi.RemoteException;
Implementation
public class SeatReservationImpl extends java.rmi.server.UnicastRemoteObject implements SeatReservationInterface
     private Seat[][] theatre;
     * Implementations must have an explicit constructor in order to declare the RemoteException
     * exception.
    * Theatre constructor makes a new movie theatre with numRows rows and numSeats
    * seats (chairs) in each row. All seats are unreserved (unoccupied) in the beginning.
    public SeatReservationImpl(int numRows, int numSeats) throws java.rmi.RemoteException
          theatre = new Seat[numRows][numSeats];
          for(int row = 0; row <theatre.length; row++)
          for(int col = 0; col<theatre[row].length; col++)
          theatre[row][col] = new Seat();
    * The method returns true if the seat at location (row, seat) is reserved.
    * The method returns false in all other cases.
    * Be careful that row numbers run from 1 to numRows, and seat numbers from
    * 1 to numSeats.
     public boolean isReserved(int row, int seat) throws java.rmi.RemoteException
         return theatre[row-1][seat-1].isOccupied();
    * Books the seat at location (row, seat) and returns true if that seat is available.
    * Returns false if that seat is already reserved.
     public boolean reserve(int row, int seat) throws java.rmi.RemoteException
          return theatre[row-1][seat-1].occupy();
    * Cancels a seat reservation at location (row, seat) is that seat was booked, and returns
    * true in that case. The method returns false if that seat had not been reserved.
     public boolean cancel(int row, int seat) throws java.rmi.RemoteException
          return theatre[row-1][seat-1].release();
    * Returns the number of reserved seats.
     public int numReservations() throws java.rmi.RemoteException
          int count = 0;
          for(int i = 0; i < theatre.length; i++)
          for(int j = 0; j < theatre[j].length; j++)
          if(theatre[i][j].isOccupied())
          count++;
          return count;
* Prints an overview over all reservations. Reserved seats are shown as "*", available seats
* as "-". For each row the row number is shown, then a couple of blanks, and then the
* reservations. An example is
* 8 -----****----
* 7 ---**---**---
* 6 ----***------
* 5 -------------
* 4 -------------
* 3 ----------***
* 2 **-------
* 1 -------------
public void showReservations() throws java.rmi.RemoteException
          for(int row = theatre.length-1; row>=0; row--)
               System.out.print((row+1) + "\t");
               for(int j = 0; j<theatre[row].length; j++)
               if(theatre[row][j].isFree())
               System.out.print("-");
               else
               System.out.print("*");
               System.out.println();

Your code is working as expected. The server executes System.out.println in showReservations() and this comes out on the server console. The client executes System.out.println() after calling numReservations and this comes out at the client. Any other expectations are misplaced.
