Question

bonjour
en ecrivant ce prg 

A.initialiser();est souligné en rouge 
aidez moi pour corriger ma faute s'il vous plaît 


package LesPoints;
public class Point2 
{
    public double abs;
    public double ord;
    public static int varStat;
    public static void main(String [] args)
   
    
    public void initialiser(double x, double y)
    {
        abs x; ord y;
    }
    
    public void afficherCoord()
    {
       System.out.println("Le point se situe en position : " + abs + " et " + ord );
     }

     public void deplacerPoint(double dx, double dy)
     {
         abs += dx; ord += dy;
     }
     
     public static double calculDistance(Points2 M, Points2 N)
     {
       double distance;
       distance = Math.sqrt( (N.abs - M.abs) * (N.abs - M.abs) + (N.ord - M.ord) * (N.ord - M.ord) );
       return distance;
     }

     public double calculDistance(Points2 P)
     {
      double distance;
      distance = Math.sqrt( (this.abs - P.abs) * (this.abs - P.abs) + (this.ord - P.ord) * (this.ord - P.ord) );
      return distance;
     }

}




package LesPoints;
public class TesterPoints2 
{   
    public static void main(String [] args)
    {
        Point2 A = new Point2();
        A.initialiser();
        A.afficherCoord();
    }
}


en metteant souris sur la ligne A.initialise();
le message suivant apparait

"the method initialiser (double,double) in the Point2 is not applicable for the arguments()"

le prg foctionne, j'ai resultat est le suivant 
Coordonnées: (0.0, 0.0) 

mais dans mon cours le resultat est indiqué: 
Cordonnées : 2.0 et 7.0 

peut tu m'expliquer pourquoi s'il te plaît

mettenant Points2 A,Points2 B et Points2 P souligné avec message
"Points2 cannont be resolved to a type"
en compilant j'ai resultat suivant
Coordonnées: (0.0, 0.0)

mais dans mon cours le resultat est:
Le point se situe en position : 2.0 et 7.0 


public static double distance(Points2 A, Points2 B) {
          return A.distance(B);
     }

     public double distance(Points2 P) {
          return Math.sqrt((this.abs - P.abs)*(this.abs - P.abs) + 
                           (this.ord - P.ord)*(this.ord - P.ord));  
     }
