is your java file called GridLayoutDemo.java?

You shouldn't write "java blahblahblah.java", just "java blahblahblahblah". Also, be aware of the classpath. In this case, you're not likely to be in trouble because of it, but in case of 3rd part libraries or with packages - well, this might be the case.
Also, a very nice thing is that you don't try to work in IDE and use just a command line - you'll learn MUCH faster. Though MUCH more painful =)
