question: gets the next key from the map . concode_field_sep Iterator iterator concode_elem_sep Map.Entry last concode_elem_sep Map map concode_elem_sep boolean canRemove concode_field_sep Object getKey concode_elem_sep Object getValue concode_elem_sep Object setValue concode_elem_sep void reset concode_elem_sep boolean hasNext concode_elem_sep String toString concode_elem_sep void remove
target: Object function ( ) { last = ( Map . Entry ) iterator . next ( ) ; canRemove = true ; return last . getKey ( ) ; }
