How to create a userdefined non Iso standard Locale

Question

Hi
I m able to create a non standard locale with following code
new locale("en_IDC")
where IDC is the non standard Country but i want to specify some settings or parameter for this locale
I want that for IDC I must be able to speciify
"LocaleString" , "Languages", "Countries", "DateTimePatterns", etc...
For std locale eg. fr_FR jvm read it from the LocaleElements_fr_FR class.
How its possible for non standard en_IDC locale
shall create the LocaleElements_en_IDC java file.
Pls help me
Thanks in advance.

Hi John,
Thanks for ur valuable reply.
I want to make one thing clear like for
suppose i have set the default locale as "fr_FR" and when i try to use any of the formater for e.g Numberformat
Here is the code
Locale objLocale = new Locale("fr","FR");
Locale.setDefault(objLocale);
double value = 12345.56;
NumberFormat nf = NumberFormat.getInstance(objLocale);
String formattedValue = nf.format(value);
System.out.println("formattedValue="+formattedValue);
The jvm automatically pick up the "java.text.resources.LocaleElements_fr_FR" resourcebudle from the cache and the number format class fetch the "NumberPatterns" keys value from the resource budle and apply it to the double.
Above thing managed by the jvm
Is the same thing is possible for userdefined Locale class which extend the ListResourcebudle
for eg. I had created following locale where
Language="xx" (fake or non existing language)
Country ="IDC"( fake or non existing language)
where i had defined some "NumberPatterns" "##,##0.###"
class LocaleElements_xx_IDC extends ListResourceBundle
getcontent(){
new Object[] {
     "NumberPatterns", new String[] {                         "#,##0.###;-#,##0.###", "\244#,##0.00; (\244#,##0.00)", "#,##0%"
when i use follwoing code for the xx_IDC locale its not formating the double value with the NumberPatterns i had specified in the class
Locale objLocale = new Locale("xx" , "IDC");
Locale.setDefault(objLocale);
double value = 12345.56;
NumberFormat nf = NumberFormat.getInstance(objLocale);
String formattedValue = nf.format(value);
System.out.println("formattedValue="+formattedValue);
when i try the above code jvm is not responding in the same way in comparision to "fr_FR" locale
Its not picking up the "NumberPatterns" which i had specified.
///according to ur reply the above thing is not possible uptill jDK 1.5 but it is possible in jdk1.6
So u want to say that the "xx_IDC" implementation is possible in jdk1.6
Pls reply
Thanks a lot.
