Hi,

Arraylist is a item collection of different datatypes.
Hashtable is a collection key value pair.

Array list is a list
In this we can add items to the list
Here we can add any datatype value, every item in arraylist
is treated as object

Hash table is a map
Here we can add data with the key
Retriving data in hash is faster then in array list.
