// the above method 
  
import java.util.*; 
import java.util.Locale.*; 
  
public class LocaleBuilderDemo { 
    public static void main(String[] args) 
    { 
  
        // Creating a new Locale.Builder 
        Locale.Builder localeBuilder 
            = new Builder(); 
  
        // setting the locale of Locale.Builder 
        Locale locale = Locale.FRANCE; 
        System.out.println("Setting the Locale:"
                           + locale); 
        localeBuilder.setLocale(locale); 
  
        // Displaying Locale.Builder 
        System.out.println("LocaleBuilder:"
                           + localeBuilder); 
  
        // Building the Locale from Locale.Builder 
        System.out.println("Building the Locale."); 
  
        Locale builtLocale = localeBuilder.build(); 
  
        // Displaying Locale.Builder 
        System.out.println("Built Locale:"
                           + builtLocale); 
    } 
}

输出：

Setting the Locale:fr_FR
LocaleBuilder:java.util.Locale$Builder@232204a1
Building the Locale.
Built Locale:fr_FR

程序2:

// Java program to demonstrate 
// the above method 
  
import java.util.*; 
import java.util.Locale.*; 
  
public class LocaleBuilderDemo { 
    public static void main(String[] args) 
    { 
  
        // Creating a new Locale.Builder 
        Locale.Builder localeBuilder 
            = new Builder(); 
  
        // setting the locale of Locale.Builder 
        Locale locale = Locale.ENGLISH; 
        System.out.println("Setting the Locale:"
                           + locale); 
        localeBuilder.setLocale(locale); 
  
        // Displaying Locale.Builder 
        System.out.println("LocaleBuilder:"
                           + localeBuilder); 
  
        // Building the Locale from Locale.Builder 
        System.out.println("Building the Locale."); 
  
        Locale builtLocale = localeBuilder.build(); 
  
        // Displaying Locale.Builder 
        System.out.println("Built Locale:"
