 +  - Override the default ''toString()'' method so it returns a string reporting the number facing up and how many sides it has, for example: ''D20 is showing 13'' 
 +  - Make a NumberCubeTester that create a 12 sides die and a 6 sided die, and the makes a loop:  
 + 
 +<code java>import java.util.Scanner; 
 + 
 +public class NumberCubeTester 
 +

 +        // make 2 new number cubes 
 +        do  
 +        { 
 +            // roll the cubes and return the sum of the 2 dice 
 +
