Java Locale.Builder setUnicodeLocaleKeyword()用法及代码示例

Java中java.util.Locale.Builder类的setUnicodeLocaleKeyword()方法用于将此Locale.Builder设置为指定的unicodeLocaleKeyword键。这意味着此方法将设置Locale.Builder实例的当前unicodeLocaleKeyword，以匹配提供的unicodeLocaleKeyword键，并键入并返回它。如果指定的unicodeLocaleKeyword为null或为空，则将删除此LocaleBuilder的unicodeLocaleKeyword。

用法:

public Locale.Builder
  setUnicodeLocaleKeyword(
    String unicodeLocaleKeywordKey, 
    String unicodeLocaleKeywordType)

参数：此方法接受两个参数：

unicodeLocaleKey：这是要为Unicode语言环境设置为此Locale.Builder实例的键String。
unicodeLocaleKeywordType：这是将设置为Unicode语言环境的此Locale.Builder实例的String类型。

返回类型：此方法返回一个Locale.Builder实例，并将此Locale.Builder的unicodeLocaleKeyword集设置为指定的unicodeLocaleKeyword。

异常：此方法引发以下异常：

IllformedLocaleException：如果指定的unicodeLocaleKeyword具有任何格式错误的字段

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

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(); 
  
        // Displaying Locale.Builder 
        System.out.println("LocaleBuilder:"
                           + localeBuilder); 
  
        // setting the unicodeLocaleKeyword 
        // of Locale.Builder 
        String unicodeLocaleKeywordKey = "asf@"; 
        String unicodeLocaleKeywordType = "afaf$"; 
  
        System.out.println("Setting the "
                           + "unicodeLocaleKeyword:"
                           + unicodeLocaleKeywordKey + "-"
                           + unicodeLocaleKeywordType); 
  
        try { 
  
            localeBuilder 
                = localeBuilder 
                      .setUnicodeLocaleKeyword( 
                          unicodeLocaleKeywordKey, 
                          unicodeLocaleKeywordType); 
  
            // Displaying Locale.Builder 
            System.out.println("Updated LocaleBuilder:"
                               + localeBuilder); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：

LocaleBuilder:java.util.Locale$Builder@232204a1
Setting the unicodeLocaleKeyword:asf@-afaf$
java.util.IllformedLocaleException:
 Ill-formed Unicode locale keyword key:
 asf@ [at index 0]
