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.

Bonjour,

J'ai réussi à régler le prob. en fait cela venait de l'embrouille due au format décimal à la française (la virgule comme séparateur de décimal). J'ai donc utilisé NumberFormat à la place de DecimalFormat, ce qui m'a permis de définir l'attribut "Locale" en "US" et ça marche.

Par contre, je n'ai pas cherché à savoir si "DecimalFormat" permettait de définir l'attribut Locale.

Merci à tous
