import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing  MessageFormat
        MessageFormat mf
            = new MessageFormat("{0, number, #}");

        // setting new Locale for
        // message format object
        // using setLocale() method
        mf.setLocale(new Locale("en-US"));

        // getting Locale
        // used in MessageFormat Object

        // display the result
        System.out.println("Locale is : " + locale);
    }
