I have the following situation
Map<Key, ListContainer> map;
public class ListContainer{
List<AClass> lst;
}
I have to merge all the lists lst
from the ListContainer
objects from a Map
map.
public static void main(String args[]){
List<AClass> alltheObjectsAClass = map.values().stream(). // continue....
}
Any idea how, using Java 8 stream API?
