Java BigDecimal can have comma instead dot?

I have a string value that I want to assign to a BigDecimal. When I update the decimal value with a number like 100.23, it works fine but when I update it with a number like 100,23 the code throws an exception. Why is that?

The BigDecimal(String) constructor documentation lists all valid formats and characters. Notice that the , is not included within this list.

If you can't be sure if your String has commas or points, you can use replace(char, char) from the String class. For example myString.replace(',', '.').

because you tried to put a "," in a number.

you can use this code to parse a number with comma:

NumberFormat.getNumberInstance(Locale.FRANCE).parse("265,858")

you should also use float or double if there is no particular reason you use decimal.
