inheritance - Override interface instead of parent class in Java -

i have class extends class (reloadableresourcebundlemessagesource) , implements interface(mymessageprovider) this:

public class custommessagesource extends reloadableresourcebundlemessagesource implements mymessageprovider{      @override     public string getmessage(string code, object[] objects, final locale locale{         try {             return getmessage(code, objects, locale);         } catch (nosuchmessageexception e) {             return code;         }     } } 

both interface , parent class have getmessage function want override interface one. code gives compile error because getmessage in parent class (reloadableresourcebundlemessagesource) final.

if override getmessageinternal() method not final, , called by getmessage() methods, can affect outcome not returning null. not need change calls getmessage() methods in code, call internal method themselves.

@override public string getmessageinternal(string code, object[] objects, final locale locale) {         string foo = super.getmessageinternal(code, objects, locale);          return foo == null ? code : foo;     } }
