Assume the availability of a method named makeStars that can be passed a non-negative integer n and that returns a String of n asterisks. Write a method named printTriangle that receives a non-negative integer n and prints a triangle of asterisks as follows: first a line of n asterisks, followed by a line of n-1 asterisks, and then a line of n-2 asterisks, and so on. For example, if the method received 5 it would print:
* * * * *
* * * *
* * *
* *
*
The method must NOT use a loop of any kind (for, while, do-while) to accomplish its job. The method should invoke printStars to accomplish the task of printing a single line.

It should use recursion and be done in Java.
