Kommunikation von 2 Klasse

[fiorelino]

Ich habe zwei public class, wie kann ich miteinander kommunizieren?

Class Grundriss beinhaltet die Oberflaeche und alle Objekte .
Class GuiClient beinhaltet prozess von nachricht verschicken und empfangen (von anderem System).

Ich habe eigentlich vor, ein paar Objekte's eigentschaften zu aendern so bald ich
eine Nachricht von anderem System bekommen habe. In diesem Fall moechte ich setVisible zu true machen, wenn ich die Nachricht von einem Agenten ueber ihre Lokation bekommen habe.

public class Grundriss extends org.eclipse.swt.widgets.Composite {
                 ...

	public Label schwBeateWaiting;
	public Label schwAnitaWaiting;
	public Label drAlbrechtWaiting;
	public Label drFrankeWaiting;
	public Label patMuellerWaiting;
	public Label patMeierWaiting;
               ...

Was ich gerne machen moechte, wenn ich eine Nachricht bekomme, dann werde ich z.B schwBeateOP2.setVisible(true) machen

						    und so on ....
//-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

						}
				}

   
			// received a schedule message

Ich weiss man koennte effektiver machen, aber im Moment fehlt mir echt die Zeit :-(

vielen Dank fuer Euere Hilfe !!

 

[The_S]

Und ich hab echt keine Zeit Fragen zu beantworten die schon 5367509 mal geklärt sind. Wofür gibt es die Forensuche?

 

[fiorelino]

tut mir Leid - ich googling ja auch ...

 

[The_S]

Also ich hab da auf anhieb ein paar Beispiele gefunden. Schon allein hier im Forum! z. B.

public class Klasse1 {

   private int zahl = 5;

   public int getZahl() {

      return zahl;
   }
}

public class Klasse2 {

   private Klasse1 kl1 = null;

   public Klasse2() {

      kl1 = new Klasse1();
   }

   private void printZahl() {

      System.out.println(kl1.getZahl());
   }
}

vielen Dank fuer Deine Hilfe!

habe auch gefunden in forum http://www.java-forum.org/de/viewtopic.php?p=87333#87333 jetzt muss ich umsetzen - ich habe ja die variablen extra alle public gemacht, damit alle Klasse die benutzen koennen ...
