Lists and util.ArrayLists

HiI have a doubt about util.ArrayLIsts. With this, I can create Lists like creating lists from scratch. I mean, ArrayLIsts uses pointers and all that stuff? Or is something completely different from the lists in which we have to create a pointer?Regards

List is an interface.

ArrayList is an implementation of List.

If this doesn't answer your question then please try and rephrase your question with less techno-babble.

In a list you can have a lot of elements. Within this elements you may have different attributes, like name, last name and phone. When you create a list, you put in every element of the list the attributes that they must have.

Then you can sort it, or delete some element, create trees, etc.

My question is:

I can do this with ArrayList

Hope is clear enough.

Kind regards
