Best way to parseDouble with comma as decimal separator?

Question

Following is resulting in an Exception:

String p=\"1,234\";
Double d=Double.valueOf(p); 
System.out.println(d);

Is there a bet

Answer 1

You can use this (the French locale has , for decimal separator)

NumberFormat nf = NumberFormat.getInstance(Locale.FRANCE);
nf.parse(p);

Or you can use java.text.DecimalFormat and set the appropriate symbols:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator(',');
symbols.setGroupingSeparator(' ');
df.setDecimalFormatSymbols(symbols);
df.parse(p);
