Boolean value not resetting

[BillyB]

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.

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.

kind regards,
