(a) Given this class definition, what would be printed out by the code System.out.println(new Friends(2))? Use text and/or diagrams to show how you derive the answer.

(b) Produce an English description of the replace method, including an explanation of the effect achieved by use of the % operator. Suggest an alternative way of achieving this effect.
