Java Locale getISO3Language()用法及代码示例

Java语言环境类的getISO3Language()方法用于获取语言环境中指定的语言的三个字母的缩写。这将是小写的ISO 639-2 /T语言代码，或者在语言环境未指定语言的情况下为空字符串。

用法:

LOCALE.getISO3Language()

参数：此方法不带任何参数。

返回值：此方法不返回任何值。

异常：如果三个字母的语言缩写不适用于指定的语言环境，则该方法将引发MissingResourceException。

以下示例程序旨在说明getISO3Language()方法的用法：

程序1:

// Java code to illustrate getISO3Language() method 
  
import java.util.*; 
  
public class Locale_Demo { 
    public static void main(String[] args) 
    { 
  
        // Creating a new locale 
        Locale first_locale 
            = new Locale("en", "IN"); 
  
        // Displaying first locale 
        System.out.println("First Locale: "
                           + first_locale); 
  
        // Displaying the language_code of this locale 
        System.out.println("Language: "
                           + first_locale.getISO3Language()); 
    } 
}

输出：

First Locale: en_IN
Language: eng

程序2:

// Java code to illustrate getISO3Language() method 
  
import java.util.*; 
  
public class Locale_Demo { 
    public static void main(String[] args) 
    { 
  
        // Creating a new locale 
        Locale first_locale 
            = new Locale("ar", "SA"); 
  
        // Displaying first locale 
        System.out.println("First Locale: "
                           + first_locale); 
  
        // Displaying the language_code of this locale 
        System.out.println("Language: "
                           + first_locale.getISO3Language()); 
    } 
}

输出：

First Locale: ar_SA
Language: ara

程序3:显示错误

// Java code to illustrate getISO3Language() method 
import java.util.*; 
  
public class Locale_Demo { 
    public static void main(String[] args) 
    { 
  
        // Creating a new locale 
        Locale first_locale 
            = new Locale("engh", "US"); 
  
        // Displaying first locale 
        System.out.println("First Locale: "
                           + first_locale); 
  
        try { 
            // Displaying the language_code of this locale 
            System.out.println("Language: "
                               + first_locale.getISO3Language()); 
        } 
        catch (Exception e) { 
            System.out.println(e); 
        } 
    } 
}

输出：
