in zeile 223 kommt immer diese fehlermeldung: illegal start of expression
wißt ihr vielleicht warum?

[Gast2]

innerhalb einer Methode kannst du nichts statisches deklarieren, sollte das ne Methode werden?

 

[Cyz44]

und wo muss ich es dann deklarieren?? sry steh grad aufm schlauch ???:L

 

[André Uhres]

Hallo Cyz44,

in dem anonymen ActionListener ist keine statische Methode erlaubt. Außerdem kann man Methoden nicht verschachteln.

btn7.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(final ActionEvent evt) {
        btn7_ActionPerformed(evt);
        Color[] Farbe = new Color[6];
        Farbe[0] = Color.white;
        Farbe[1] = Color.yellow;
        Farbe[2] = Color.red;
        Farbe[3] = Color.green;
        Farbe[4] = Color.blue;
        Farbe[5] = Color.black;
        jlbl1.setBackground(Farbe[getRandomNumber()]);
        jlbl1.setOpaque(true);
    }

    private int getRandomNumber() {
        int number = (int) (Math.random() * 6);
        return number;
    }
});

Gruß,
André

Als Methode sollte sie so aussehen

  public int getRandomNumber()
  {
      int number = (int) (Math.random() * 6);
      jlbl1.setBackground(Farbe[getRandomNumber()]);
      jlbl1.setOpaque(true);
      return number;
  }

dann pack sie auch zu deinen Methoden und rufe sie auf, wo du willst.

Dazu müsstest du aber diese Zeile

 Color[] Farbe = new Color[6];

nach oben zu deinen Attributen verschieben.

Dann hast du noch einen Button und ein int schwarz genannt!

Und eine btn9ScrollPane kann ich nicht finden!

 

[Marco13]

Hast du dich, als du den Code erstellt hast, nicht irgendwann gefragt: "Mann' so'n dreck - das muss doch einfacher gehen..." ?

 

[Cyz44]

Vielen Vielen Dank, es klappt jetzt !!

 

[Cyz44]

@Marco13

Ja hab ich 😀 Ich weiß das es wahrscheinlich viel einfacher gehen würde, aber in der Schule haben wir es halt nur so gelernt. Kannst du mir ein paar Tips geben, wie man diesen extrem aufwändigen Code etwas kürzen könnte? ( weil du hast recht- wirklich Glücklich bin ich darüber nicht...)

 

[Fab1]

Hab mir jetzt nicht deine kompletten 600 Zeilen Code angeschaut, aber eine JLabels könntest du zum Beispiel mithilfe einer Schleife erstellen in einem Array speichern und über den Index ansprechen.

 

[bygones]

das sind mehrere hundert zeilen code kopien... wie schon gesagt, nicht jedes label einzel definieren, sondern in einem array/collection.

Weiterhin einen LayoutManager nutzen.

 

[ARadauer]

jo auf jeden Fall arrays Galileo Computing :: Java ist auch eine Insel - 3 Klassen und Objekte ansehen ;-)

 

[Cyz44]

Ok Danke. Dann werd ich mich mal bisschen mehr mit Arrays beschäftigen.
