java - NumberFormatException for String while parsing float -

-

this error caused due different system locale. use dot decimal separator.

i tried set default locale when application starts i'm getting same exception.

locale.setdefault(locale.us);

stacktrace:

 caused by: java.lang.numberformatexception: input string: "6,2" @  sun.misc.floatingdecimal.readjavaformatstring(floatingdecimal.java:2043) @  sun.misc.floatingdecimal.parsefloat(floatingdecimal.java:122)  @  java.lang.float.parsefloat(float.java:451)

it looks code using float.parsefloat. doesn't use locale settings. docs:

returns new float initialized value represented specified string, performed valueof method of class float.

and valueof has detailed grammar, , includes this:

to interpret localized string representations of floating-point value, use subclasses of numberformat.

so basically, default locale irrelevant here. if want parse "6,2" should using numberformat locale using comma decimal separator.
