    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    non-static variable nylro cannot be referenced from a static context
    The nylro variable only exists when an instance of the class is created.
    Some solutions:
    move it into the main() method
    make it static so the code in the static method: main() can reference it
    create an instance of the class and use the reference to that instance to refer to nylro
    If you don't understand my answer, don't ignore it, ask a question.
