getLanguage

public String getLanguage()

Returns the language code for this locale, which will either be the empty string or a lowercase ISO 639 code.

NOTE: ISO 639 is not a stable standard-- some languages‘ codes have changed. Locale‘s constructor recognizes both the new and the old codes for the languages whose codes have changed, but this function always returns the old code. If you want to check for a specific language whose code has changed, don‘t do

 
 if (locale.getLanguage().equals("he")) 
    ... 
 

Instead, do

 
 if (locale.getLanguage().equals(new Locale("he", "", "").getLanguage())) 
    ...
