This is a very simple class, but the results from typing 11, 22 , 44, or 111 for example are quite amuseing :p.
Running it a couple of time you will soon ask you self, Wtf? :p, I know why it does do it, I just find it amusing lol.

Java:

import java.util.Scanner;     public class Ch04Ex02 {        public static void main (String [] args) {          Scanner input = new Scanner (System.in);          double cost = 0.75 + 1.00;          System.out.println ("Enter the diameter of the pizza in inches: ");          double diameter = input.nextDouble();          cost = cost + (0.05* (diameter * diameter));          System.out.println ("The cost of making the pizza is: $"+ cost);          input.close();            }    }
