Program 1:
// 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(); // Displaying Locale.Builder System.out.println("LocaleBuilder: " + localeBuilder); // clearing the extensions // of Locale.Builder System.out.println("Clearing the" + " extensions."); localeBuilder = localeBuilder.clearExtensions(); // Displaying Locale.Builder System.out.println("Updated LocaleBuilder: " + localeBuilder); }} |
Output:
LocaleBuilder: java.util.Locale$Builder@232204a1 Clearing the extensions. Updated LocaleBuilder: java.util.Locale$Builder@232204a1
Program 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(); // Displaying Locale.Builder System.out.println("LocaleBuilder: " + localeBuilder); localeBuilder = localeBuilder .setExtension('u', "ca-japanese"); // Displaying Locale.Builder System.out.println("Extension set " + "of LocaleBuilder: " + localeBuilder); // clearing the extensions // of Locale.Builder System.out.println("Clearing the" + " extensions."); localeBuilder = localeBuilder.clearExtensions(); // Displaying Locale.Builder System.out.println("Updated LocaleBuilder: " + localeBuilder); }} |
Output:
