Java library/api which converts language code to language name

Question

Is there a Java library/api which , given an iso language code, returns the corresponding language name. For example zh-cn should return chinese, en should return english and so on.

Answer 1

The Java Locale class can do this:

new Locale("zh", "cn").getDisplayName();
--> Chinese (China)

You just have to parse the language/country names.

Answer 2

You don't need a library; you can use java.util.Locale for this.

Locale locale = new Locale("zh", "cn");
System.out.println(locale.getDisplayLanguage());

This will print

Chinese
