Question

I need help with fixing this java program as described in the image below:

import java.util.Scanner;
 
public class LabProgram {
   
   /* TODO: Write recursive drawTriangle() method here. */
 
 
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);
      int baseLength;
      
      baseLength = scnr.nextInt();
      drawTriangle(baseLength);
   }
}

 

Write a recursive method called draw Triangle() that outputs lines of '*' to form a right side up isosceles triangle. Method draw Triangle() has
one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9
spaces before the first '*' on the first line for correct formatting.
Hint: The number of '*' increases by 2 for every line drawn.
Ex: If the input of the program is:
3
the method drawTriangle() outputs:
*
19
***
Ex: If the input of the program is:
the method drawTriangle() outputs:
*
***
*****
