Boolean value not resetting

I am working on a recursive call that checks to see if numbers are divisible by 10 and return false if not. I can't figure out why if(g != 0) ans = false; doesn't change the value of ans in the method and pass back false to the main method. Thank you for your help.

Code:

---

public class MultiplesOfTen {

        public static boolean dividedBy10 (int x[], int r, int y, boolean ans){
                               
                int g = (x[r]%10);
               
                if(g != 0)
                        ans = false;
                else if ( r < y){
                        r++;
                        dividedBy10(x, r, y, ans);
                          }
                return ans;
        }

        public static void main(String[] args) {
                int [] nums = {30,55,80,70,100};
                int r = 0; //set for the index value
                int len = nums.length -1;
                boolean ans = true;
                System.out.print("Are all the numbers dividable by 10?");
                System.out.println("The answer is: " + dividedBy10(nums, r, len, ans));

        }

}

Two remarks:

1) a parameter doesn't exist outside the method call;
2) you're ignoring the method return value in the else-clause.
