Thanks

I am working on the above link but I am not able to figure it out how to write code which will make use of some of those methods. Do anyone have any examples ?

What specifically are you trying to do? Are you sure you need to implement the interface, as opposed to just using it?

[suresh kamsa]

I wanted to implement collection interface and work with it.

Hi Suresh,
You don't implement the collection interface directly, you implement a subinterface like so:
Map m = new Hashmap();
or
List l = new LinkedList();
or
Set s = new HashSet();
Then, you can add Objects to the collection!

[Ron Newman]

What kind of collection do you want to implement that isn't already provided in standard Java?
