Locale Constants in Java

Locale Some of the constants.

These are useful constants in the Locale class of Java

PRIVATE_USE_EXTENSION: The key for the private use extension ('x').

UNICODE_LOCALE_EXTENSION: The key for Unicode locale extension ('u').

Approach

Java

import java.util.Locale;

public class LocaleConstants {
    public static void main(String[] args) {

        System.out.println("The key for the private use extension " +
       Locale.PRIVATE_USE_EXTENSION);

        System.out.println("The key for Unicode locale extension " + 
      Locale.UNICODE_LOCALE_EXTENSION);

        System.out.println("CANADA constant is " + Locale.CANADA);

        System.out.println("CANADA_FRENCH constant is " + 
      Locale.CANADA_FRENCH);

        System.out.println("CHINA constant is " + Locale.CHINA);

        System.out.println("CHINESE constant is " + 
                            Locale.CHINESE);

        System.out.println("ENGLISH constant is " + 
                           Locale.ENGLISH);

        System.out.println("FRANCE constant is " + Locale.FRANCE);

        System.out.println("FRENCH constant is " + Locale.FRENCH);

        System.out.println("GERMAN constant is " + Locale.GERMAN);

        System.out.println("GERMANY constant is " +
                         Locale.GERMANY);

        System.out.println("ITALIAN constant is " + Locale.ITALIAN);

        System.out.println("ITALY constant is " + Locale.ITALY);

        System.out.println("JAPAN constant is " + Locale.JAPAN);

        System.out.println("JAPANESE conatant is " +
                   Locale.JAPANESE);

        System.out.println("KOREA constant is " + Locale.KOREA);

        System.out.println("KOREAN constant is " + Locale.KOREAN);

        System.out.println("PRC constant is " + Locale.PRC);

        System.out.println("ROOT conatant is " + Locale.ROOT);

        System.out.println("SIMPLIFIED_CHINESE constant is " +
        Locale.SIMPLIFIED_CHINESE);

        System.out.println("TAIWAN constant is " + Locale.TAIWAN);

        System.out.println("TRADITIONAL_CHINESE constant is " + 
         Locale.TRADITIONAL_CHINESE);

        System.out.println("UK Constant is " + Locale.UK);

        System.out.println("US Constant is " + Locale.US);

    }
}
