Tutorial

Preparing Eclipse

1. First,begin by visiting here and choose Eclipse IDE for Java Developers (pay attention to 32bit and 64bit versions)
2. Unzip the downloaded file int /Eclipse_Platform/Basics directory
3. Start Eclipse by going into your newly created directory (/Eclipse_Platform/Basics/) and click the Eclipse executable
4. 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

1. Now that you have Eclipse open and have defined a workspace, click File->New->Java Project
2. 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
3. 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

1. The package explorer allows one to explore the contents of various packages within their project
2. 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)
3. 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

Editing Java elements is as easy as double clicking on a class, header file, or any other file that has text based data. Double clicking on the file will open a new window to edit the Java element.

Creating a Java class

• Select a package in the package explorer, right click: New->Class
• Give the class a meaningful name, click finish
• Note: At least one class that you make should have "public static void main(String [] args)" CHECKED

Renaming Java elements

1. First, locate the Java elements you want to rename in the Package Explorer
2. 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
3. Java actually renames all instances of the previous file name to the new file, which is pretty nice

Moving and copying Java elements

1. 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

1. 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)
2. Finish by selecting ok
3. 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

1. First, locate the element you want to view the declaration for
2. Once located, right click on the elements name and select Open Declaration

Viewing the type Hierarchy

To view the type hierarchy of any Java element by right clicking the file and selecting Open Type Hierarchy

Searching the workbench

To use Eclipses Search function, you can either go to the toolbar and select Search->Search and type your search there, or you can hit ctrl+f while you have a file open to search within that file, which is the preferred way to do it in my opinion
