BJP3 Exercise 12.2: writeNums

Language/Type: Java recursion recursive programming
Author: Whitaker Brand (on 2013/04/01)

Write a method writeNums that accepts an integer parameter n and prints the first n integers starting with 1 in sequential order, separated by commas. For example, the following calls produce the following output:

Call Output
writeNums(5); 1, 2, 3, 4, 5
writeNums(12); 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Your method should throw an IllegalArgumentException if passed a value less than 1. Note that the output does not advance to the next line.
