CS 1302 Lab 9 – This is a tutorial covering Lists: ArrayList, LinkedList, and PriorityQueue. There are 6 stages to complete this lab: Stage Title Text Reference 1 The ArrayList Class 20.2, 20.4 2 The LinkedList Class 20.4 3 Speed Comparison: ArrayList vs. LinkedList 20.4 4 The Comparator Interface 20.5 5 Static Methods for Lists & Collections 20.6 6 The PriorityQueue Class 20.9 To make this document easier to read, it is recommend that you turn off spell checking in Word: Choose: File, Option, Proofing At the very bottom, check: spelling errors…” and grammar errors…” “Hide “Hide The ArrayList Class In this stage we will demonstrate some of the methods in the ArrayList class that we have not considered before. Read (no action required) – A collection in programming is a general term to refer to any class that holds a group of items. The ArrayList class (Ch. 11) is a collection and so is an array, and a Stack. In this chapter we will study a number of other collection classes. The ArrayList class inherits its behaviors through the interfaces shown on the right. Note that Collection is the root interface and List is a subinterface. (Two abstract subclasses: AbstractCollection and AbstractList implement the behaviors). In this stage, we will consider some of the methods shown in red in the class diagram above. Setup Do the following: – Establish a Workspace Create a folder on your drive where you will put your lab or use an existing one. – Run Eclipse As the program begins to run, it will ask you to navigate to the Workspace you want to use. – Create a Project Create a Java project with the name, lab09_lastNameFirstInitial, e.g. lab09_gibsond. – Create a package named list_examples. Run Example Read (no action required) The addAll method: – public bool addAll(Collection<? Extends E> c)
