List Operations

• To allow duplicate elements to be stored in a collection, a list can be used. A list can not only store duplicate elements, but can also allow the user to specify where the element is stored. The user can access the element by index.

• The ArrayList class and the LinkedList class are concrete implementations of the List interface. Which of the two classes you use depends on your specific needs.

• Common operations: add, addAll, get, indexof, lastindexof, and remove.

• Enumeration is a Java interface used to extract the elements of a container like vector one at a time successively.
