public String getDisplayCountry(Locale inLoc)

参数：该方法接受一个Locale类型的参数inLoc ，表示名称的本地化显示。
返回值：此方法返回适合给定语言环境和用户的国家名称。
异常：如果参数 inLoc 为 null，则该方法抛出NullPointerException 。
下面的程序说明了 getDisplayCountry() 方法的工作：
示例 1：

Java

// Java code to illustrate getDisplayCountry() method
 
import java.util.*;
 
public class Locale_Demo {
    public static void main(String[] args)
    {
 
        // Creating a new locale
        Locale first_locale
            = new Locale("English", "In");
 
        // Displaying first locale
        System.out.println("First Locale: "
                           + first_locale);
 
        // Displaying the country_name of this locale
        System.out.println("Country: "
                           + first_locale
                                 .getDisplayCountry(
                                     new Locale("Spanish",
                                                "Spain")));
    }
