Accessing int's, String's by methods.

Hey, I'm having a newbie problem with accessing specific integers (let's take that for instance) in void methods.

Code:

---

public class Methods
{
    public void setVars()
    {
        int num1 = 4;
        int num2 = 12 * 5 / 3;

    }

    public void calcVars(int num1, int num2, int calcs)
    {
      Methods calc = new Methods();
      calcs = num1 + num2;
    }

    public static void main(String args[])
    {
       
        System.out.println(calcs);
    }

}

---

The variable calcs should only calculate what is being given by num1 and num2. I forgot how to access that, if that's the error o.o.

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code
at Methods.main(Methods.java:18)
Java Result: 1

In main method you have not declare the variable calcs. Without declaring you cannot use any.

Here,

Code:

---

Methods calc = new Methods();

---

you have create an object to the same class (refereed). What you really going to do that with it?
