Problème avec DecimalFormat
Bonsoir,
J'utilise DecimalFormat dans le but de n'avoir que 2 chiffres après la virgule et je rencontre un souci. Voici le code :
Code:

public void actionPerformed(ActionEvent e) {
DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
//df.setGroupingSize(3);
Object source = e.getSource();
if (source == jTextFieldPU) {
String pu = ""+ ((new BigDecimal(jTextFieldQuantite.getText()))
.multiply((new BigDecimal(jTextFieldPU.getText()))));
jTextFieldHT.setText(df.format(Double.parseDouble(pu)));
System.out.println(pu);
}
if (source == jComboTaux) {
String pTTC = ""+ (((new BigDecimal(jComboTaux.getSelectedItem().toString()))
.multiply((new BigDecimal(jTextFieldHT.getText())).divide(new BigDecimal("100")))).
add(new BigDecimal(jTextFieldHT.getText())));
jTextFieldTTC.setText(df.format(Double.parseDouble(pTTC)));
System.out.println(pTTC);
}
} |
et j'obtiens NumberFormatException.

J'ai mis certaine partie du code en rouge car je crois que le problème vient de là mais je n'arrive pas à le régler.
Aidez-moi SVP.
