Hi, I am getting a rather odd error message when I try compile a java program. I have attached the original java code and a copy of the error message in a .txt file. Any help you guys can offer will be much appreciated.
I'll help you by offering some friendly advice here
don't just attach your code and errors and assume we have the time, or every moment work on a pc with Java runtime installed on it.
show the relevant code and the error messages you get in your post, that would save us a lot of work and make us more willing to help you out
Edit: I've just read the last line of your error-message (about all the effort I was going to put into it)
seems to me that you're calling a non existing method.

I thought it would be easier to just attach the files rather than plaguing this thread with lots of source code lol. I don't have a problem with posting the code here so thats what I will do. Thank you for your advice.

lol omg there was no point in posting all of this because I just had that light bulb moment and figured it out. I forgot to add the the Swing Layout Extension in the Libraries.... blame my professor who is supposed to be a Dr in his field. NooB!
