Great solutions here, just one more option that taking into consideration handling of null values:

Map map = new HashMap<>();

Map stringifiedMap = map.entrySet().stream()
             .filter(m -> m.getKey() != null && m.getValue() !=null)
             .collect(Collectors.toMap(Map.Entry::getKey, e -> (String)e.getValue()));
