Java Locale getISO3Country()用法及代碼示例

Java中的Locale類的getISO3Country()方法用於獲取指定語言環境的國家或地區代碼。這將是大寫的ISO 3166 3字母國家/地區代碼，如果語言環境未指定國家/地區，則為空字符串。

用法:

LOCALE.getISO3Country()

參數：此方法不帶任何參數。

返回值：此方法不返回任何值。

異常：如果three-letter國家/地區縮寫不適用於指定的語言環境，則該方法將引發MissingResourceException。

以下示例程序旨在說明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()); 
    } 
}

輸出：

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()); 
    } 
}

輸出：

First Locale: ar_SA
Country: SAU

            System.out.println("Country: "
                               + first_locale.getISO3Country()); 
        } 
        catch (Exception e) { 
            System.out.println(e);
