Advance Java Series Session 1 - Addition to CFM in Java 6

In java 6 we have a deque is what double ended queue we can say double ee where we can get the value from both the ends where you can push the value from both the end. Navigableset where you can navigate from any way and even you can search for the closest matches based on the value navigablemap that is similar to the navigable set where you can search for the entries based on the given values for key. So you have over here like a sealing floor kind of the method which gives you the nearest entry for that specific value which you are passing through. Array deque is a implementation double ended queue in the form of array.
