Program: How to access top level class variables from static member classes?

Since static code does not have a this reference, you can not access
instance variable of a top level class. You can only access static
members of a top level class.

package com.java2novice.nested.classes;

public class MyStatMemClassAcsVars {
	public static String staticVar = "You can access me!!!";
	private String privVar = "You cannot access me";
	public static class ChildClass{
		public void myMethod(){
			//you can access all static members of 
			//top level class
			//you cannot access instance members of
			//top level class
			//below line gives compile error
	public static void main(String a[]){
		MyStatMemClassAcsVars.ChildClass cc = new MyStatMemClassAcsVars.ChildClass();

You can access me!!!
