Description (Last modified by grhoten)

When parse a string with grouping characters, user may expect that only well formatted string can be parsed. This ability can detect some inattentive errors. For example, type 1.2 (one point two) as 1,2 (one comma two). One project has postponed a bug due to this limitation.

public class Sutdy { public static void main(String[] args) throws ParseException { //String str = "1,2"; String str = "1,23,456,7890"; Locale locale = Locale.ENGLISH; NumberFormat nfa = NumberFormat.getInstance(locale); DecimalFormat nf; if (nfa instanceof DecimalFormat){

nf = (DecimalFormat) nfa;

} else {

System.err.println("wrong."); return;

} System.out.println(nf.toPattern()); Number n = nf.parse(str,new ParsePosition(0)); System.out.println(n); System.out.println(nf.format(n)); } }

This feature was already implemented by #5206. With setParseString(true), the sample code above works as the bug author expected. So I'll close this as a duplicate.
