Ravi Kumar · Answer

There are following difference between ArrayList and Hashtable :- A hashtable store data as name, value pair. While an ArrayList only value is store. If you want to access value from the hashtable, you need to pass name. While in arraylist to access value, you need to pass index value. In a hastable you can store different type of data like int, string etc. While in arraylist you can store only similar type of data. for more http://www.etechpulse.com/2013/08/what-is-difference-between-arraylist.html

Hi Ali, Array List 1.Array List is a List. 2.In Array list we can only add items to the list. 3.Here we Can Add any datatype value,Every item in Arraylist is treated as object. 4.Index Numeric. 5.Data in Arraylist is stored in as only the value. 6.Slow when come to search Hash Table 1.Hash Table is a map. 2.In Hashtable we can add data with the key. 3.Retrieving by key in Hashtable is faster than retrieving in Arraylist. 4.Index can be string also. 5.Data in Hashtable is stored in the key-value pair. 6.Fast when searching.
