package FilePackage;
 
import javax.ejb.Remote;
 
@Remote
public interface FileRemote {
 
	 public int emfiler(int element);
	    public int défiler();
	    public boolean estVide();
	    public boolean estPleine();
	   public int sommet();
	   public void affichage();
	  public int taille();
	  public int priorite();
 
}
