    ArrayList--> Index based. HashTable-->Key based.

    1) Hash table store data as name, value pair. While in array only value is store. 2) To access value from hash table, you need to pass name. While in array, to access value, you need to pass index number. 3) you can store different type of data in hash table, say int, string etc. while in array you can store only similar type of data.

    Hashtable is key/value pair based collection where Arraylist is index based. arraylist canbe easily sorted but hashtable is not.
