Name =name;  This. index =index; }     Public Staticstring GetName (string index) { for(Season s:season.values ()) {if(S.getindex (). Equals (index))returnS.getname (); }        return NULL; }     PublicString GetIndex () {returnindex; }     Public voidsetindex (String index) { This. index =index; }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }}

Iterating through an enumeration class

 Public Static string GetName (string index) {        for  (Season s:season.values ()) {            if  return  s.getname ();        }         return NULL ;    }
