getDisplayLanguage

public abstract String getDisplayLanguage(String languageCode,

For example, if languageCode is "fr" and locale is en_US, getDisplayLanguage() will return "French"; if languageCode is "en" and locale is fr_FR, getDisplayLanguage() will return "anglais". If the name returned cannot be localized according to locale, (say, the provider does not have a Japanese name for Croatian), this method returns null.

Parameters:

locale - the desired locale

Returns:

the name of the given language code for the specified locale, or null if it's not available.

Throws:

NullPointerException - if languageCode or locale is null
