returnere samlet antal

Hejsa igen.

Jeg har nu et spørgsmål, som hedder:

"Programmér metoden spectators (Cinema). Metoden skal returnere det samlede antal tilskuere for filmen movie. Test metoden spectators fra exam-metoden i Driver-klassen"

Jeg er lidt i tvivl om hvordan jeg gør det. Skal det også ind i en forløkke eller? Min klasser ser således ud nu:

public class Driver
{   
    public static void exam() {
       
    CinemaShow cs1 = new CinemaShow("Gangsteren", "2012-12-01", "21:00", 234);
    CinemaShow cs2 = new CinemaShow("Party On", "2012-01-01", "10:00", 231);
    System.out.println(cs1.toString());
    System.out.println(cs2.toString());
   
    Cinema c = new Cinema("Biografen");
    c.add(cs1);
    c.add(cs2);
   
    System.out.println(c.mostCrowded().toString());
       
       
    }

   
}


public class CinemaShow
{
    private String movie, date, time;
    private int spectators;

    public CinemaShow(String movie, String date, String time, int spectators)
    {
        this.movie = movie;
        this.date = date;
        this.time = time;
        this.spectators = spectators;
    }

   
    public String toString()
    {
        return(movie + ", " + date + ", " + time + ", " + spectators);
    }
   
    public int getSpectators() {
   
        return (spectators);
    }
}


import.java.util.*;

public class Cinema
{
    private String cinemaName;
    private ArrayList<CinemaShow> listofcinemaShows = new ArrayList<CinemaShow>();

    public Cinema (String cinemaName)
    {
        this.cinemaName = cinemaName;
    }

   
    public void add(CinemaShow cs) {
       
        listofcinemaShows.add(cs);
    }
   
    public void remove (CinemaShow cs) {
   
        listofcinemaShows.remove(cs);
    }
   
    public CinemaShow mostCrowded() {
     
        CinemaShow res = listofcinemaShows.get(0);
        for(int i = 1; i < listofcinemaShows.size(); i++) {
        if (res.getSpectators() < listofcinemaShows.get(i).getSpectators()) {
       
        res = listofcinemaShows.get(i);
       
        }

      }
   
    return res;
  }
 
  public void int spectators (String movie) {
   
   
 
    }
 
}
