BJP3 Exercise 12.7: writeChars

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

Write a method writeChars that accepts an integer parameter n and that prints out n characters as follows. The middle character of the output should always be an asterisk ("*"). If you are asked to write out an even number of characters, then there will be two asterisks in the middle ("**"). Before the asterisk(s) you should write out less-than characters ("<"). After the asterisk(s) you should write out greater-than characters (">"). For example, the following calls produce the following output:

Call Output
writeChars(1); *
writeChars(2); **
writeChars(3); <*>
writeChars(4); <**>
writeChars(5); <<*>>
writeChars(6); <<**>>
writeChars(7); <<<*>>>
writeChars(8); <<<**>>>

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