RE: What is the difference between HashTable and HashMap?
Hashtable does not allow null values or null keys, whereas hash map allows null keys and null values. Hashtable is synchronzied whareas hashmap is not synchronized. In case of single thread using hashmap is faster than the hashtable. In case of multiple thereads, using hashtable is advisable.
