#1

You can seed it with a known number and then parse it for the characters you want.

您可以使用已知编号对其进行播种,然后针对所需的字符进行解析。

import com.google.gwt.i18n.client.NumberFormat;

NumberFormat fmt = NumberFormat.getDecimalFormat();
double value = 1234.5;
String formatted = fmt.format(value);
String thousandSeparator = formatted.substring(1,2);
String decimalSeparator = formatted.substring(5,6);

#2

import com.google.gwt.i18n.client.LocaleInfo;

String decimalSeparator = LocaleInfo.getCurrentLocale().getNumberConstants().decimalSeparator();
String thousandSeparator = LocaleInfo.getCurrentLocale().getNumberConstants().groupingSeparator();
