FYI: Linked Listed are not part of the AP Computer Science subset

Lists

A list is a collection of objects
A list can only store objects of a class, not primitive types
Wrapper classes are provided to get around this limitation
Lists are implemented through the List interface
An ArrayList implements the List interface
A LinkedList also implements the List interface (not in AP subset)
List methods you need to know are: size, add, get, set, remove

Lists
