I'm having some problems with my regional settings, namely with the getCurrencyInstance(). I tried compiling an example class, but got errors. Changing the "$" from the example into local currency format, however, didn't help either.

I don't want to tamper with my regional settings just to compile one class, any ideas how to avoid this and similar problems now and in future code?

Hi There,

Firstly a quick Admin matter, it's Javaranch policy to specify your full first an last name as you screen name.

Right onto your question, Can you show us the class that you tried to compile and what the error was? Basically we need more information to help you (see my sig on a guide for how to ask questions on Java ranch)

OK, name changed (I didn't see the no ficticios policy, sorry) and here's the code:

import java.text.*;

public class ParseDeclare {

public float parseIt(String s) throws ParseException {

NumberFormat format = NumberFormat.getCurrencyInstance();
Number num = format.parse(s); //may generate exception

return num.floatValue();
}

public static void main(String[] args) {

ParseDeclare parser = new ParseDeclare();
String s;

s = "$45.67";

try {
System.out.println(parser.parseIt(s));
}

catch (ParseException e) {
System.err.println("Invalid string \""+s+"\"");
}

finally {
System.out.println("Original string was \""+s+"\"");
}
}
}

Oh, and the error that appears after I run the class:

init:
deps-jar:
compile-single:
run-single:
Original string was "$45.67"
Invalid string "$45.67"
BUILD SUCCESSFUL (total time: 0 seconds)
____________________________________________________

I am certain it's a problem with the regional settings (mine: Currency 123.456.789,00 kn) and the getCurrencyInstance(), I just need a solution.

As I've said, I tried changing "$45.67" to "24,56 kn" with no effect. That is, except for the 5th and 6th line of the Output changing into:

Original string was "24,56 kn"
Invalid string "24,56 kn"

Do your regional settings specify . as the decimal separator or , ?

You have the Windows Regional Options set to US, right? That was my point, you won't get this exception in the US, but you will outside of the US. I need this compiled, preferably without adjusting my Settings, so help would be appreciated.

Thanks!

I have played a little around with your code - the currency symbol "Kn" need to be in the front for it to work...

Just as I thought - it is the locale.

When I try the original code but use Locale.US when getting the currency instance, it works like a charm.

I guess that makes sense. $ is unknown in both Croatian and Dutch locales as far as currencies are concerned. Likewise, it would ignore the . and return 4567.0. That's because both in Croatia and in The Netherlands we use , as the decimal symbol, not .
