// We can use stl container list as a double 
// ended queue to store the cache keys, with 
// the descending time of reference from front 
// to back and a set container to check presence 
// of a key. But to fetch the address of the key 
// in the list using find(), it takes O(N) time. 
// This can be optimized by storing a reference 
//	 (iterator) to each key in a hash map.

Below are the Big O performance of common functions of different Java Collections.


List                 | Add  | Remove | Get  | Contains | Next | Data Structure
---------------------|------|--------|------|----------|------|---------------
ArrayList            | O(1) |  O(n)  | O(1) |   O(n)   | O(1) | Array
LinkedList           | O(1) |  O(1)  | O(n) |   O(n)   | O(1) | Linked List
CopyOnWriteArrayList | O(n) |  O(n)  | O(1) |   O(n)   | O(1) | Array
