Difference between Array List and Hash Table:-

Array List

• Array list is a collection of objects(may be of different types).
• We can add items to the Array List.
• Array List’s size can be changed dynamically
• index elements in an ArrayList with a numeric index.

Hash table

• Hash table is also collection which takes a key corresponding to each values.
• Hash table we can add data with the Key.
• A Hash table class is dynamically expands and contracts but doesn't impose an order on the elements like an array does. 
• index elements in a Hash Table with a key.  Such a key is often a string...
