How can I create a Locale with a specific script code?

Question

I'm trying to convert this String az_AZ_#Latn, found here, to a Locale but I'm unable to parse the #Latn part.

If I do new Locale("az_AZ_#Latn") I lose the #Latn part (the Script code).

I've tried as well using the LocaleUtils from commons-lang but I get an error saying that it's an invalid format.

As written in the docs:

It is not possible to set a script code on a Locale object in a release earlier than JDK 7.

But you can use the Locale builder to make it like this:

Locale locale = new Locale.Builder().setLanguage("az").setRegion("AZ").setScript("Latn").build();

You can get the Script it by calling locale.getScript()

Edit:

Here's a method I made for converting a string into a locale (doesn't work for extensions):

public static Locale stringToLocale(String locale){
    if(locale == null || locale.isEmpty()) return null;
    String[] parts = locale.split("_");
    if(parts.length == 1) return new Locale(parts[0]);
    if(parts.length == 2) return new Locale(parts[0],parts[1]);
    if(parts.length == 3) 
        if(parts[2].charAt(0) != '#') return new Locale(parts[0],parts[1],parts[2]);
        else return new Locale.Builder().setLanguage(parts[0]).setRegion(parts[1]).setScript(parts[2].substring(1)).build();
    if(parts.length == 4) return new Locale.Builder().setLanguage(parts[0]).setRegion(parts[1]).setVariant(parts[2]).setScript(parts[3].charAt(0)=='#'? parts[3].substring(1):null).build();
    return null;
}
    //works for the toString output expect for extensions. test: for(Locale l:  Locale.getAvailableLocales()) System.out.println(l.equals(stringToLocale(l.toString())));
   // output : true true true...

usage:

Locale l = stringToLocale("az_AZ_#Latn");

Locale.Builder is able to handle script information for locales. The documentation of the Builder class also includes this example code:

Locale aLocale = new Locale.Builder().setLanguage("sr")
                                     .setScript("Latn")
                                     .setRegion("RS")
                                     .build();

By using the builder you would have to do the splitting of the string yourself and also removal of any unsupported characters like #.

Using the 3-arg contructor java.util.Locale.Locale(String, String, String) is not correct since you probably don't intend to specify a variant using Latn but a script instead.
