Maybe you shouldn't give the factorial of 1 the value 2 as it is returning in your first "if" construct. Now I am not expert but I think this should work:

public class facto{
    public static void main(String[] args){
        System.out.println(dust(5));
    }

static int dust(int n)
   {
       int output;
       if(n==1){
         return 1;
       }
       
       output = dust(n-1)* n;
       return output;
   }
}


I suppose that in your version the recursion is not able to complete properly because of "maybe" your trying to both return the value and calculate it at the same time. Hope the code snippet helps, I am just a beginner myself so apologies if I didn't get it right. P.S I know I haven't considered the condition of the input being 0.
