Best of luck to you. Junior Member BLANK WINDOW SOLUTION: Like those before me, I was pulling my hair out trying to fix the blank window problem. I tried PC (Windows 10), Mac (El Capitan) and nothing would work. As the problem was platform neutral, I suspected it was a Java problem, though I couldn't go back to 1.6 due OS compatibility issues. It turns out that adding a single line to the code fixes it: private static final long serialVersionUID = 1L; before the run method.

It appears the serialVersionUID is a mandatory requirement in Java 1.8 that wasn't the case in 1.6. Good luck to you all; now I just have to wait for my hair to grow back, after pulling most of it out in frustration! • Attachment: (Size: 735.78KB, Downloaded 718 times).

I am going through courses on SEE. I also had the blank Java window when I ran a java file from the Assignments download.

I was able to get them to run in JDK 1.8 using the standard Eclipse. Here's what I did.

There is a Stanford Eclipse plug-in. I found instructions for that. Under the installation instructions for Mac or Windows, whichever you use, there is a link to the Stanford plug-in. Then go to and download, unzip and import into Eclipse the BlankKarelProject.zip file.

Now, I don't know a lot of stuff. But when I imported that Blank one and ran that java file, I got a blank world to load. Then in that java application window, I clicked the Load World button.

A file window opened up and I navigated to the file on my local disc the world named 'CollectNewspaperKarel' and then I see what the world is supposed to look like for that assignment. I notice for the imported Assignment file there is no src or lib dirs. My best guess is I can work on/edit the assignment in the respective assignment's java file then copy paste it into the BlankKarel.java file, run, see it happen in the world I selected.

Karel the Robot was quite a success. Karel was used in introductory computer science. Macintosh is somewhat different from running it under Windows.
