程序 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);

        // setting the unicodeLocaleKeyword
        // of Locale.Builder
        String unicodeLocaleKeywordKey = "nu";
        String unicodeLocaleKeywordType = "thai";

        System.out.println("Setting the "
                           + "unicodeLocaleKeyword: "
                           + unicodeLocaleKeywordKey + "-"
                           + unicodeLocaleKeywordType);

        localeBuilder
            = localeBuilder
                  .setUnicodeLocaleKeyword(
                      unicodeLocaleKeywordKey,
                      unicodeLocaleKeywordType);

        // Displaying Locale.Builder
        System.out.println("Updated LocaleBuilder: "
                           + localeBuilder);
    }
}

输出:

LocaleBuilder: java.util.Locale$Builder@232204a1
Setting the unicodeLocaleKeyword: nu-thai
Updated LocaleBuilder: java.util.Locale$Builder@232204a1

        // of Locale.Builder
        String unicodeLocaleKeywordKey = "asf@";
        String unicodeLocaleKeywordType = "afaf{content}quot;;

        System.out.println("Setting the "
                           + "unicodeLocaleKeyword: "
