Answer Posted / chandan phukan
Two main differences between Hastable and HashMap are
1. Hashtable is synchronised but HashMap is not.
2. Hashtable does not allow "null" key but HashMap allows
"null" Key.
However one point to remember is that only one "null" key is
allowed in HashMap but multiple "null" values are allowed in
HashMap.
