JtextField auslesen und in JLable einfuegen

[Huha92]

Moinsen, im Rahmen meiner Hausaufgabe zu morgen soll ich eine klitzekleine Klasse schreiben, in der ich in einem Fenster ein Standardadressfeld habe, mit TextFields, in denen Name, Nachname, PLZ usw. beschrieben wird. Dies soll nun in einem Ausgabefenster ausgegeben werden, in JLables.

Was habe ich gemacht? Sondierende Methoden der einzelnen Textfelder um den Inhalt zurueckzugeben. (Hauptfenster)
ein Beispiel:

 public String getNachname(){
        return name.getText();
    }

Und die dazu passende set-Methode im Ausgabefenster:

    public void setNachname(){
        this.nachname.setText(NewApplication.getNachname());
    }

nun kommt die Fehlermeldung "non-static method can't be referenced from a static context"

habe nun gegooglet, auch http://www.java-forum.org/stichwort...ic-method-cant-referenced-static-context.html gefunden, aber habe wirklich keinerlei Ahnung, wie ich das Problem nun loesen kann...

Waere dankbar, wenn ich eine exakte Erklaerung des Problems bekomme, eine Loesung will ich mir dann schon selbst erarbeiten...

Danke schoen schonmal

Du brauchst eine Referenz auf dein Hauptfenster, sonst kannst du ja nicht die Methode aufrufen.

 

[AmunRa]

NewApplication ist eine Klasse und diese hat keine static Methode die getNachname heist.

Du brauchst eine Instanz der Klasse NewApplication.

D.h.

du hast sicher irgenwo in deinem Code eine zeile die ähnlich aussieht

NewApplication app = new Application();

nun kannst du von app die Methode auffrufen.

app.getNachname

Jetzt hab ich es wahrscheinlich da hingesetzt, wo es garnicht hin darf, denn der Compiler meckert nicht mehr, aber uebergeben werden leere Strings... :/
Nun beide Quellcodes direkt:

Nun dein Code kompiliert bei mir, wenn ich in den Methoden

fehlerAusgeben1 und btn_okActionPerformed auskommentiere, da du ja den SourceCode für die Klassen Fehler und Ausgabe nicht gepostet hast.


Was ist daher dein Frage was funktioniert nicht?

[AmunRa]

Nun das Problem das du hast ist, dass wenn du wenn du deine setAusgabe aufrufst,
machst du wieder

NewApplication app = new NewApplication();

damit greifst du aber nicht auf das Object zu in dem der User zuvor die eingaben gemacht hast.

Du musst dir eine Refernz des Objects übergeben.

dass machst du am besten in dem du dir in deiner Ausgeben Klasse eine var anlegst

private NewApplication app;

und den Konstruktor so anpasst:

public Ausgabe(NewApplication t){
  app=t;
  
}

dann kannst du in der setAusgabe()
die Zeile von Oben löschen.

unn musst du nur noch in der Methode btn_okActionPerformed

den Aufruf so schreiben

Ausgabe aus= new Ausgabe(this);

 

[Huha92]

ouch. Dankeschoen, mir kam die Zeile in setAusgabe() schon etwas spanisch vor, aber wusste nicht, wo ich sie haette sonst hinschreiben koennen. dankeschoen fuer die Antwort, warum und weshalb konnt ich auch nachvollziehen. =)
