Question:
Write a recursive method called starString that accepts an integer as a parameter and prints to the console a string of stars (asterisks) that is 2n (i.e., 2 to the nth power) long. For example,
- starString(0) should print * (because 20 == 1)
- starString(1) should print ** (because 21 == 2)
- starString(2) should print **** (because 22 == 4)
- starString(3) should print ******** (because 23 == 8)
- starString(4) should print **************** (because 24 == 16)
The method should throw an IllegalArgumentException if passed a value less than 0 .
