First, download the GDSV via the Download Page.
Once downloaded, simply run the Windows Installer file (.msi).
Follow the on-screen instructions to install the GDSV.

In order to have your data structure class be displayed/used in the GDSV you must implement the GenericDataStructureViewable interface that has the arrayRepresenationOfDataStructure() method.

In order to compile your data structure class with the new interface, you must have the GDSV.jar library added to your classpath. To do this in BlueJ simply select Tools -> Preferences -> Libraries Tab and add GDSV.jar (You can find GDSV.jar in the GDSV installation folder: C:\Program Files\GDSV\ default for windows).

The GDSV is an application to help code and check student-created data structures. In order to help you see the process, here is a complete example (we use an ArrayStack class):

1. Create a class
2. Import the GDSV classes: import gdsv.*;
3. Write the data structure (Use this code)
4. Make sure your class realizes arrayRepresenationOfDataStructure()
5. Compile

Once you have successfully installed the GDSV, included the libraries, and coded a data structure, you are ready to run the GDSV. To do so, double click on the "Run the GDSV" icon where you installed the GDSV. (You may also execute the GDSV.jar file).

When the GDSV starts up, just follow the on screen instructions. You may also review the Change Log and other Auto Updater features by selecting the "Update" tab.

Click "Continue..." to continue past the Automatic Updater; this will start the GDSV.

With the GDSV now open you are ready to load your data structure into the program. Following the on-screen instructions, browse your computer for your data structure's CLASS file. Next, select what type of data structure it is (you can always change it later). Finally, click "Start" to load your data structure into the GDSV!

From here you can call methods you coded and see the changes on your data structure visually.
