Hi, ArrayList is not like Array-backed Lists, right? I remember Array-backed Lists is fix sized (can not delete or add). And ArrayList has a dynamic size.

ArrayList is built using an array, that is why it is called ArrayList. Please go through the details of ArrayList either from the API or from any certification book to learn more.
