Hi Ayan.

If you simply use a System.out.println() on the list, it displays quite nice.
In case you need some kind of formatted output, please detail.

Cheers,
Claudiu

Sorry,for not being precise with my query.
Actually,I need to access each (KEY,VALUE) pair from each hashmap and then do some updation on the elements of each hashmap and then display it.

You would have to iterate through the list- you can use Enhanced for loop. so you get HashMap instances on each iteration, use it to get the key-value pairs.
So if you can convert this into code, we would be able to help you further
