Difference between array list and hash table?

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.



Thanks
