what is the difference between HashMap And HashTable?

Answer Posted / stalin

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
