HashMap: HashMap offers 0(1) lookup and insertion. The Last element of the LinkedList contains null in the pointer part of the node because it is the end of the List so it doesn’t point to anything as shown in the above diagram. Comparable and Comparator 13. LinkedHashMap 10. The way I could mitigate the JSON Array to collection of LinkedHashMap objects problem was by using CollectionType rather than a TypeReference.This is what I did and worked:. If you iterate through the keys, though, the ordering of the keys is essentially arbitrary. Comparable and Comparator 13.
