是否有ISO 3166-1国家/地区代码的开源java枚举

摇篮

OSGi的

Bundle-SymbolicName: com.neovisionaries.i18n
Export-Package: com.neovisionaries.i18n;version="1.22.0"

此代码在Sun Java 6中获得242个国家:

String[] countryCodes = Locale.getISOCountries();

尽管ISO网站声称有249个ISO 3166-1-alpha-2代码元素,但javadoc链接到相同的信息.

以下是我使用国家/地区代码+国家/地区名称生成枚举的方法:

package countryenum;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Locale;

public class CountryEnumGenerator {
    public static void main(String[] args) {
        String[] countryCodes = Locale.getISOCountries();
        List list = new ArrayList(countryCodes.length);

        for (String cc : countryCodes) {
            list.add(new Country(cc.toUpperCase(), new Locale("", cc).getDisplayCountry()));
        }

        Collections.sort(list);

        for (Country c : list) {
            System.out.println("/**" + c.getName() + "*/");
            System.out.println(c.getCode() + "(\"" + c.getName() + "\"),");
        }

    }
}

class Country implements Comparable {
    private String code;
    private String name;

    public Country(String code, String name) {
        super();
        this.code = code;
        this.name = name;
    }

    public String getCode() {
        return code;
    }


    public void setCode(String code) {
        this.code = code;
    }


    public String getName() {
        return name;
    }


    public void setName(String name) {
        this.name = name;
    }


    @Override
    public int compareTo(Country o) {
        return this.name.compareTo(o.name);
    }
}

如果您已经依赖Java语言环境,那么我建议使用简单的HashMap而不是为国家/地区等创建新类.

如果我只依赖Java Localization,那么我将如何使用它:

private HashMap countries = new HashMap();
String[] countryCodes = Locale.getISOCountries();

for (String cc : countryCodes) {
    // country name , country code map
    countries.put(new Locale("", cc).getDisplayCountry(), cc.toUpperCase());
}

填写地图后,您可以在需要时从国家/地区名称获取ISO代码.或者您也可以将其作为国家/地区名称映射的ISO代码,只需相应地修改"put"方法即可.
