从 Java 中的欧元货币字符串中删除空格

Question

I have a method that convert a number into a currency, for "USD" and "GBP" it's working good, but with "EUR" the NumberFormat it's rendering a string with a space between the symbol and the number € 1.207.987,00 rather then dollar and pound "$1,207,987.00" , "£1,207,987.00" . I tried use replace and replace all to remove this but nothing works for me, follow the code:

 public static void main(String[] argsd) {
        Number rawNumber = 120798700;
         NumberFormat numberFormat = NumberFormat.getCurrencyInstance(Locale.forLanguageTag("nl"));
         Currency currency = Currency.getInstance("EUR");
         numberFormat.setCurrency(currency);
         String numberRemoveSpaces = numberFormat.format((rawNumber.floatValue() / 100)).replaceAll("\\s+", "");
        System.out.println(numberRemoveSpaces);
    }

Answer 1

If you want to remove it, try this:

String numberRemoveSpaces = numberFormat.format((rawNumber.floatValue() / 100)).replaceAll("\\p{Z}","");

That removes any kind of whitespace or invisible separator.

Answer 2

You can use the following, instead of your current replaceAll() :

replaceFirst("\\u00A0", "")

The Unicode value of U+00A0 is a non-breaking space (see here ). This is the specific character being used to separate the currency symbol from the amount.

You can also choose to build a custom format as follows:

NumberFormat nf = NumberFormat.getCurrencyInstance();
DecimalFormatSymbols dfs = new DecimalFormatSymbols();
dfs.setCurrencySymbol("€");
dfs.setGroupingSeparator('.');
dfs.setMonetaryDecimalSeparator(',');
((DecimalFormat) nf).setDecimalFormatSymbols(dfs);
System.out.println(nf.format(rawNumber.floatValue() / 100));

This also gives the same output:

€1.207.987,00

Answer 3

感谢大家的所有答案，但根据http://www.bubblefoundry.com/blog/2013/11/formatting-dutch-currency-amounts/荷兰货币的默认格式在符号和数字之间有空格，所以我将与空间保持一致。
