Private instance method

Question

I want to have a private instance method in my application that changes the values of some variables. Then I want to use these variables in the main method. Is it possible to do this?
When I tried to do it, I recieved the following error message:
non-static variable cannot be accessed in static context
Can anybody help me?

import java.util.*;
public class Test {
  public static void main(String[] args) {
    Test test = new Test();
    test.showData();
    test.setMyString("xyz");
    test.setMyInt(55);
    System.out.println("Main1 - myInt="+test.getMyInt()+", myString="+test.getMyString());
    test.mungeData();
    System.out.println("Main2 - myInt="+test.getMyInt()+", myString="+test.getMyString());
  private int myInt = 3;
  private String myString = "abc";
  public Test() { }
  public String getMyString() { return myString; }
  public void setMyString(String s) { myString = s; }
  public int getMyInt() { return myInt; }
  public void setMyInt(int i) { myInt = i; }
  public void mungeData() { myInt++; myString+="x"; }
  public void showData() { System.out.println("Test - myInt="+myInt+", myString="+myString); }
}
