DISCLAIMER:
THIS QUESTION WAS NOT MENT TO BE ARGUMENTATIVE!!!!!!!

What is fastest and less memory draining way of searching a key-value pair? I will be storing items in a key-value like relation and I need to access them quickly. Should I use a SQLite database? A Map? A Hashtable? A HashMap? Please give some advantages/disadvantages of using whatever method of searching.
