You should really use an IDE rather than notepad or w.e you use. Download Eclipse from here [Only registered and activated users can see links. ] An IDE makes writing Java a lot more easier as it tells you the errors as you write your code also makes reading code a lot less of a task for newbs and not just that there's a whole lot more. Then learn a little more about Java by reading here: [Only registered and activated users can see links. ] The reason why I am telling you this is because the CMD console is telling you what is wrong and even without knowledge of Java you should know what the problem is or anyone who understands plain English. The problem is these days is that people are too lazy to read a tutorial... It will take you maybe even a couple of hours to learn the basics, you may find it boring or amazingly fun but once you get the hang of it you're off and you can do all sorts of things then you just learn more as you go along! No one wants to help you with this simple answer because you haven't tried to learn and without learning you're not going to get anywhere. If you listen to this it will benefit you, also you might take a big interest into programming and then make a career out of it if you enjoy it that much... who knows ayy? I wish you luck young one.
