Java Locale getISO3Country()用法及代码示例

Java中的Locale类的getISO3Country()方法用于获取指定语言环境的国家或地区代码。这将是大写的ISO 3166 3字母国家/地区代码，如果语言环境未指定国家/地区，则为空字符串。

用法:

LOCALE.getISO3Country()

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three-letter国家/地区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getISO3Country()方法的用法：

示例1:

// Java code to illustrate getISO3Country() 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 country_code of this locale 
        System.out.println("Country: "
                           + first_locale.getISO3Country()); 
    } 
}

输出：

First Locale: en_IN
Country: IND

示例2:

// Java code to illustrate getISO3Country() 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 country_code of this locale 
        System.out.println("Country: "
                           + first_locale.getISO3Country()); 
    } 
}

输出：

First Locale: ar_SA
Country: SAU

示例3:显示错误

// Java code to illustrate getISO3Country() method 
import java.util.*;

    { 
  
        // Creating a new locale 
        Locale first_locale 
            = new Locale("ar", "tez"); 
  
        // Displaying first locale 
        System.out.println("First Locale: "
                           + first_locale); 
  
        try { 
            // Displaying the country_code of this locale 
            System.out.println("Country: "
                               + first_locale.getISO3Country()); 
        } 
        catch (Exception e) { 
            System.out.println(e);
