class Shape {
     public Shape() {
             System.out.println("Shape constructor");
     }//from w ww  . j a  va 2 s.co m
     public class Color {
             public Color() {
                     System.out.println("Color constructor");
             }
     }
 }

class Main {
     public static void main(String []args) {
              Shape.Color black = new Shape().Color(); // #1
     }
}

What will be the output of the program?
