My Locale

[Enkita mody]

HELLO

I couldn't figure out this.I'm wondering what does it mean ? I were expecting default locale of my system but there is nothing.
Now what do i with that object? what is the use of that object, could you elaborate about it?

import java.util.Locale;
class MyLocale 
{
	public static void main(String[] args) 
	{
		Locale defaultLocale=new Locale.Builder().setRegion(null).setLanguage("").build();
		System.out.println(defaultLocale.getDisplayName());
	}
}

---------- Run ----------

why not use the getDefault method? http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Locale.html#getDefault%28%29

In setRegion() , If region is null or the empty string, the region in the Builder returned is removed.
Same for setLanguage()

http://docs.oracle.com/javase/7/docs/api/java/util/Locale.Builder.html#setRegion%28java.lang.String%29

You have created a Locale with no region or language. This is the same as the Locale.ROOT locale.

I were expecting default locale of my system but there is nothing.

You need to do as Saifuddin Merchant has suggested.

Now what do i with that object?

That's entirely up to you.

what is the use of that object

Can you show me API, which says it is ROOT LOCALE ? Would you elaborate it ?

[Tony Docherty]

Did you read the thread I linked you to?
As for the API docs do a google for something like "Java Locale api docs 1.6"

I didn't find any evidence which says below statement creates a ROOT Locale object i.e. Locale.ROOT

Locale defaultLocale=new Locale.Builder().setRegion(null).setLanguage("").build();

Me neither, but I did find:
"Builders can be reused; clear() resets all fields to their default values."
and a little look at the specific methods expands on that.

And if you're not prepared to take Tony's word for it (and he seems a fairly knowledgeable chap), then TEST IT.

Apologies, I thought I'd copied an extract of the docs into the thread.

The docs for Locale.ROOT say "The root locale is the locale whose language, country, and variant are empty ("") strings."
And for Locale.Builder.setLanguage() and setRegion() they they say "Sets the language. If language is the empty string or null, the language in this Builder is removed." and "Sets the region. If region is null or the empty string, the region in this Builder is removed" respectively.

So Locale defaultLocale=new Locale.Builder().setRegion(null).setLanguage("").build(); creates a Locale without a region or language which is in essence the Locale.ROOT object.

Nice.
