The HashMap class is roughly equivalent to Hashtable,
except that it is unsynchronized and permits nulls.
(HashMap allows null values as key and value whereas
Hashtable doesnt allow).
HashMap does not guarantee that the order of the map will
remain constant over time. HashMap is unsynchronized and
Hashtable is synchronized.
