Cannot find class or type named "EXAMPLE"

I keep getting this error, and I don't know why it is not working.

To help others read your problem (and copy / test your code) please edit your post, highlight your code, format your code with CTRL-o, and save.

Did you create a folder named EXAMPLE and put the sketch file in it, then try to run it in the Processing IDE?

Don't do that. Instead, open a new sketch, paste the code in. When you save it, the enclosing folder and the main file will be renamed to have the same name. E.g.:

MyOpenKinect / MyOpenKinect.pde

It needs to be this way to compile; Processing handles making the folder and file names match automatically when you start in Processing.

@jeremydouglass I tried doing that, but now I get this error.

Exception in thread "Thread-245" java.lang.NullPointerException at processing.app.SketchCode.getDocumentText(SketchCode.java:228) at processing.app.ui.Editor.prepareRun(Editor.java:2716) at processing.mode.java.JavaEditor.prepareRun(JavaEditor.java:1781) at processing.mode.java.JavaEditor$34.run(JavaEditor.java:1095) at java.lang.Thread.run(Thread.java:745)

I don't know. Maybe try:

• Closing Processing and reopening it.
• Launching an example sketch from the examples menu -- does nothing run, or just not this sketch?
• If this is a p5.js sketch, have you confirmed that you are in p5.js mode, and not default / Java mode?
• Did Processing ever work before, or is this the very first time using it on this machine? If nothing at all is working, have you tried uninstalling it and reinstalling it?
