Answer Posted / tarun kumar
class Hashtable was part of the original java.util and is a
concreate implementation of a Dictionary class. In java2 it
is reengineering it so that it also implements the Map
interface.
Thus it is now integrated into the collections framework.
class HashMap implements Map interface.
Because, Hashtable is a concreate implementation of
Dictionary class, is Legacy class, all legacy classes are
synchronized. So,thats why Hashtable is sunchronized.
I can say that both Hashtable and HashMap are same, accept
synchronization.
