Java Locale class

The Java Locale class object represents a specific geographic, cultural, or political region. It is a mechanism to for identifying objects, not a container for the objects themselves. A Locale object logically consists of the fields like languages, script, country, variant, extensions.

Syntax

public final class Locale
   extends Object
   implements Cloneable, Serializable

Example 1

package tests;
import java.util.*;
public class JavaLocaleExample1 
{
   public static void main(String[] args) 
   {
      // create a new locale
      Locale locale1 = new Locale("EN", "INDIA");

      // print locale
      System.out.println("Locale: " + locale1);

      // print language
      System.out.println("Language: " + locale1.getDisplayLanguage());
   
      // print country 
      System.out.println("Country Name: "
                                 + locale1.getDisplayCountry());
      
      // get a hash code and print it
      System.out.println("HashCode for this locale: " + locale1.hashCode());
   }
}

Test it Now

Output:

Locale: en_INDIA
Language: English
Country Name: INDIA
HashCode for this locale: -2034354048

Example 2

import java.util.*;
public class JavaLocaleExample2 {
   public static void main(String[] args) 
   {
      // create a new locale
      Locale locale1 = new Locale("ENGLISH", "US", "WIN");

      // print locale1
      System.out.println("Locale1 name: " + locale1);

      // Use of toString() 
      System.out.println("String representation of Locale1: " + locale1.toString());

      // create a new locale
      Locale locale2 = new Locale("fr", "FRANCE", "WIN");

      // print locale2
      System.out.println("Locale2: " + locale2);

      // Use of toString() 
      System.out.println("String representation of Locale2: " + locale2.toString());
   }
}

Test it Now

Output:

Locale1 name: english_US_WIN
String representation of Locale1: english_US_WIN
Locale2: fr_FRANCE_WIN
String representation of Locale2: fr_FRANCE_WIN
