public class Solution {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int n = in.nextInt();
String str="#";
for (int i=0;i<n;i++)
{
System.out.printf("%"+n+"s%n",str);
str=str+"#";
}
}

I inspired by your solution.
good to see your implemenation , by seeing your code i found that i was uncessary using an extra loop
The "extra" loop is hidden by the printf. So what? Complexity is the same.
can you please explain how this line wokrs
System.out.printf("%15s","##"+"\n");
