Java large decimal format exception

Why does the following code throw a Java number format exception?

BigDecimal d = new BigDecimal("10934,375");

Solution

Yes, BigDecimal class does not consider any locale in its constructor. It needs a string, which can be read in the Javadoc of this constructor:

If you want to parse according to different locales and use commas as as decimal separators, you need to use Java. Net with specific locales text. DecimalFormat.

Example:

DecimalFormat fmt = new DecimalFormat("0.0",new DecimalFormatSymbols(Locale.GERMAN));
fmt.setParseBigDecimal(true);
BigDecimal n = (BigDecimal) fmt.parse("10934,375");

Note: you need to get an instance of decimalformat (a subclass of numberformat) so that you can call the setparsebigdecimal method Otherwise, it returns a double instead. It is a binary floating-point number. The binary floating-point number is cannot accurately represent many decimal fractions This will lead to the loss of accuracy in many cases
