Java: Assume the availability of a method named makeStars that can be passed a n

Question

Java:

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 makeStars to accomplish the task of printing a single line.

   for(int i=n;i>=1;i--)
   {
       for(int j=1;j<=i;j++)
       System.out.print("*");
       System.out.print(" ");
   }
  
}
   public static void main (String[] args) throws java.lang.Exception
   {
       // your code goes here
      
       makeStars(5);
