Question

Bonjour!!! ce programme ci dessoum'a souffer beaucoup j'ai pas compris ou est le probleme void Calculer_actionPerformed(ActionEvent e) { int i; if (i1.isSelected()) { double A = Double.parseDouble(A.gettext()); int N = Integer.parseInt(N.getText()); double Temp = 1.0; double Result = 1.0; double P; for (i = 1; i <= N; i++) { Temp = Temp * (i / A); Result = Result + Temp; } P = (i/Result) * 100.0; P.setText(" " + P); } else if (i2.isSelected()) { double A = 0; int N = N.gettext(); double P = Double.parseDouble(P.gettext()); double Temp = 1; double Result = 1; do { A = A + 0.001; for ( i = N; i > 0; i--) { Temp = Temp * (i / A); Result = Result + Temp; } Result = (i / Result) * 100; } while (Result != P); A.setText(" " + A); } else if (i3.isSelected()) { double A = A.gettext(); int N = 0; double P = P.gettext(); double Temp = 1; double Result = 1; do { N++; for (i = N; i > 0; i--) { Temp = Temp * (i / A); Result = Result + Temp; } Result = (i / Result) * 100; } while (Result != P); N.setText(" " + N); } else jLabel5.setText("Un seul champ doit être indéfinie"); } les erreurs sont:

Bonjour
double A = Double.parseDouble(A.gettext());
int N = Integer.parseInt(N.getText());
Il y a peut etre des conflits : entre test variable, (tes variables locales double A et int N et tes variables A et N qui sont a priori des label.
essaye de trouver d'autre noms pour les variables locales.
