Find Sum of Digits of Number Simple and Recursive in Java

Simple

class SimpleSum{
    public static void main(String args[]){
	int Int = 475849;

	int temp = Int;
	int sum=0;

	while(temp!=0){
		
	sum += temp%10;
	temp /= 10;

	}

	System.out.println("Sum of Digits is " + sum);
	
    }
}

Recursive

class RecurSum{
	private int Int = 475849;
	private int recursiveSum(int x){

	if(x==0)
	return 0;
	
	int sum = recursiveSum(x/10) + x%10;
	return sum;

	}

	public void example(){
	
	System.out.println(recursiveSum(Int));

	}
}
