how to convert List<Map<String, String>> into the list containing the values of the map in java8

Question

List<Map<String,String>> - this is given

I want to get List<String> of values of the map.

Answer 1

If I understand correctly what you mean you can do something like this:

List<Map<String, String>> listOfMaps = ...;
List<String> values = listOfMaps.stream()
    .flatMap(map -> map.values().stream())
    .collect(Collectors.toList());

Answer 2

List< String > valuesList = new ArrayList<>(yourmap.values());
