HashMap :
->It is a key,value pair.
->key are not duplicated but values can be duplicated.
->Null key is possible.
->It is not Synchronized by default.
Hashtable:
->It is also key,value pair but both are Strings only.
-> Keys are not duplicated but values can be duplicated.
->Null insertion is not possible of both(key and value).
->It is Synchronized by default.
