1. Array good for index based retrieval
2. HashTable & HashMap good for random retrieval
3. HashMap not synchronized, HashTable synchronized, hence slower where synchronization is not required; HashMap requires external synchronization using Collections class, where synchronization is required
4. Vector like array, only resizable. Performance can be improved by estimating proper initial size
