The Java Collections Framework is chock full of useful abstract classes, interfaces, and concrete classes that you can use to handle your collections of stuff. Some of the classes you may be most interested in are the General-purpose Implementations like HashSet, ArrayList, and LinkedList. These are concrete classes that allow you to easily work with groups of common elements. For more information on LinkedList, check out this LinkedList Tutorial.
