Write a method called writeNums that takes an integer n as a parameter and prints to the console the first n integers starting with 1 in sequential order, separated by commas. For example, consider the
following calls:
writeNums(5);
System. out. println(); // to complete the line of output
writeNums(12);
System. out. println(); // to complete the line of output
These calls should produce the following output:
1, 2, 3, 4, 5
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. Write a simple
main program to call the recursive method for the examples of 5 and 12 above.
