List

One of the collection types defined in the java.util package is List.

• List is an interface.
• List guarantees insertion-order; the order you add elements into a list is the same order that you will iterate through them.
• List allows duplicate elements. (Some collections do not.)

Since List is an interface, we instantiate an implementing class.

• ArrayList is a class that implements List.

List<String> myList = new ArrayList<>();

• LinkedList and Vector are other classes that implement List.
