Not convinced. Giving a straight answer like that, Kamlesh Kumar, doesn't help anybody learn or do their work. If somebody posts a question and is directed to the API documentation for List<E>, he should be able to read what its 25 methods are and work out which to use. Or at least ask "Should I use xxx() or yyy()?"
I have pulled rank and taken the liberty of deleting the answer. I hope you don't mind, Rob Robert and Jesper.
