:( ich werd mein kopf gegen tisch gefühl nicht so wirklich los ...

illegal forward reference wäre meines wissens nach etwas in der art
Code:
String s = s;
Code:
String s = s;
Code:
String s = s;


ich habe keine ahnung ob du sowas in deinem code machst, du bist ja recht knausrig mit der preisgabe deines codes. ob der fehler wirklich bei deinem BigDecimal passiert? keine ahnung, aber ein guter anfang wäre zb den fehler komplett zu posten, eventuell auch gleich mal den ganzen relevanten code?

Habe das Problem gefunden.
Code:
Term = Term + new java.math.BigDecimal(Display.getText());
Code:
Term = Term + new java.math.BigDecimal(Display.getText());
Code:
Term = Term + new java.math.BigDecimal(Display.getText());
geht nicht. Nur ohne Term +
also
Code:
Term = new java.math.BigDecimal(Display.getText());
Code:
Term = new java.math.BigDecimal(Display.getText());
Code:
Term = new java.math.BigDecimal(Display.getText());
.

Java Code:
Term = Term.add(new java.math.BigDecimal(Display.getText()));
Java Code:
Term = Term.add(new java.math.BigDecimal(Display.getText()));
Java Code:
Term = Term.add(new java.math.BigDecimal(Display.getText()));

ahja Danke!

Hatte es aber so
Code:
java.math.BigDecimal Temp = new java.math.BigDecimal(Display.getText());
Term = Term.add(Temp);
Code:
java.math.BigDecimal Temp = new java.math.BigDecimal(Display.getText());
Term = Term.add(Temp);
Code:
java.math.BigDecimal Temp = new java.math.BigDecimal(Display.getText());
Term = Term.add(Temp);
gemacht.

Bitte Thread Schließen.

Hat es einen Grund wieso du nicht die Klassen importierst und stattdessen so was schreibst?
Java Code:
private javax.swing.JButton Additionszeichen;
    private javax.swing.JTextField Display;
    private javax.swing.JButton SymbolKomma;
    private javax.swing.JButton ZifferAcht;
    private javax.swing.JButton ZifferDrei;
    private javax.swing.JButton ZifferEins;
    private javax.swing.JButton ZifferFünf;

        Display.setText(Display.getText() + "0");
    }

        Display.setText(Display.getText() + "2");
    }                                      


Wieso nicht eine generelle Methode
Java Code:
private void ZifferMouseClicked(MouseEvent evt, int clicked) {
        if(ZahlIstGanz) {Display.setText(""); ZahlIstGanz = false;}
        Display.setText(Display.getText() + Integer.toString(clicked));
}
Java Code:
private void ZifferMouseClicked(MouseEvent evt, int clicked) {
if(ZahlIstGanz) {Display.setText(""); ZahlIstGanz = false;}
Display.setText(Display.getText() + Integer.toString(clicked));
}
Java Code:
private void ZifferMouseClicked(MouseEvent evt, int clicked) {
        if(ZahlIstGanz) {Display.setText(""); ZahlIstGanz = false;}
        Display.setText(Display.getText() + Integer.toString(clicked));
}
