non static variable cannot be referenced from static context?

Question

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

You might like to read through [Understanding Instance and Class Members](http://docs.oracle.com/javase/tutorial/java/javaOO/classvars.html) — MadProgrammer, Sep 16 '13 at 01:33
One of solutions would be moving your variables to main method. — Pshemo, Sep 16 '13 at 01:34
You need an `instance` of your class (i.e. `object`) to reference these variables. — PM 77-1, Sep 16 '13 at 01:35

try this is code to use the member variable inside the main function you need the class object
vars v= new vars();

  public class vars {

            byte b = 127;
            byte c = 1;

            public static void main(String[] args) {
        vars v=new vars();
            System.out.println((v.b + v.c));


            }
        }
