Re: just a simple array code. please help
Please edit your post and wrap your code with code tags:
[code=java]
YOUR CODE GOES HERE
[/code]
to get highlighting and preserve formatting.
The nylro variable only exists when an instance of the class is created.non-static variable nylro cannot be referenced from a static context
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.
