non static variable cannot be referenced from static context?

non static variable cannot be referenced from static context?

I'm new to java and I have been exploring the different variable types.
Right now I am trying to determine is printed when I add 1 to a byte
variable of value 127 (the maximum value for a byte var). This is what my
code looks like:
public class vars {
byte b = 127;
byte c = 1;
public static void main(String[] args) {
System.out.println(b + c);
}
}
and on my System.out.println line I get the error message that my
non-static variables, b and c, cannot be referenced from a static context.
How should I fix this? Is there a better way to do this project in
general?
Thanks
