Welcome to the Ranch

Please do not add new questions to an old thread. Fortunately I can create a new thread from your post.
Please copy‑and‑paste all code and errors. I ran your code and did not get the error you quoted. You did however manage to write string instead of String.

[Jesper de Jong]

Java is case-sensitive. That means that "System" is not the same as "system", and "String" is not the same as "string". You have to get the spelling exactly right; if the name of a class has a capital letter, then you must write it exactly like that.
You write:

public static void main(string[] args) 

Class String is with a capital S. So that should be:

public static void main(String[] args)

It's also easier to get used to the conventions if you use them yourself. Following standard Java conventions classes always start with a capital (like String and System), and variables and methods with a lower-case letter. So while it makes no difference to whether it works or not, Loopy is a better class name than loopy.
