==Tutorial==
===Preparing Eclipse===
# * First,begin by visiting [http://http://www.eclipse.org/downloads/ here] and choose Eclipse IDE for Java Developers (pay attention to 32bit and 64bit versions)# * Unzip the downloaded file int /Eclipse_Platform/Basics directory# * Start Eclipse by going into your newly created directory (/Eclipse_Platform/Basics/) and click the Eclipse executable# * There will be a dialog box that opens that requests the location of your workspace, enter the following: '''./wksp/{app type}''' where {app type} is something along the lines of 'lab', 'simple', 'hello', ect
===Creating your first Java project===
# * Now that you have Eclipse open and have defined a workspace, click File->New->Java Project# * After doing so a window will popup requiring you to enter a name for your Java Project, enter any name appropriate to the work you will be doing# * Click the next button, followed by the finish button, and you have no created your first Java Project
===Browsing Java elements using the package explorer===
# * The package explorer allows one to explore the contents of various packages within their project# * By default, package explorer is open in eclipse on the far left of your screen (if it is not open, Navigate->Show In->Package Explorer will open it again)# * There will be a tree diagram in the Package Explorer, displaying your Java Project, packages, src folder, and all class, header files, ect
===Editing Java elements===
===Renaming Java elements===
# * First, locate the Java elements you want to rename in the Package Explorer# * Once you have located your file right click on the Java element, select Refactor->Rename and then choose the new name you want for the file# * Java actually renames all instances of the previous file name to the new file, which is pretty nice
===Moving and copying Java elements===
# * Moving Java elements can be done in various ways such as:** Right clicking the Java element, selecting Refactor->Move** Simply dragging and dropping the Java element** Selecting Refactor in the top menu and then selecting move# * You then choose the new destination of the file you are attempting to move/copy (you can also create a new location/folder if need be)# * Finish by selecting ok# * Copying and pasting is as simple as highlighting the desired text, hitting ctrl+c then pasting by pressing ctrl+v
===Navigate to a Java element's declaration===
# * First, locate the element you want to view the declaration for# * Once located, right click on the elements name and select Open Declaration
===Viewing the type Hierarchy===
===Running your programs===
*Ensure that the *NOTE specified in class creation is adhered to:
** public static void main(String [] args), Must exist in a class
* There are several ways to run your programs in eclipse including:
** You can right click a java project or package and select run as (which gives numerous options in which to run your program)
** And you can also use the keyboard shortcut Ctrl+F11
 
===Debugging your programs===
*Select your Java project in the package explorer, right click: Debug As->Java Application
===Evaluating expressions===
 
* Evaluating expressions requires you to be in Debug Perspective before doing anything
* Once in debug perspective, highlight the line in which you want to evaluate the expression for
* Then, in the toolbar, select Context->Inspect
 
===Evaluating snippets===
 
* TO evaluate a snippet, we must first create a scrapbook page
** This is done by File->New->Other->Java->Java Run/Debug->Scrapbook Page
* A window will pop up asking for both a folder and file name, enter these
* An editor will now pop up where you can enter your code snippets that you wish to have evaluated
* To view the results, right click on the snippet and select display
 
===Using the Java browsing perspective===
===Writing and running JUnit tests===
*Select a package in the package explorer, right click: New->JUnit Test Case
**Give it a meaningful name, Click Finish
*Ensure your class "extends TestCase"
*Create functions within your class, JUnit will automatically call them if they adhere to the naming conventions: function name = "test" + x
**public void testEquivs()
*Select your Java project in the package explorer, right click: Debug As->JUnit Test
