Recursion - Zero Problem

import java.util.Scanner;

public class FindingDigitsExample {
	
	public static int digit=0; //Digit has to be static and at the outside of the findDigit method.
	
	public static int findDigit(int number) { //Recursive functions can not have void.	

			if(number!= 0) {
				digit++;
				return findDigit(number/10);
			}
		
			else if(number == 0) {		
				return digit;
			}
		
			else //for invalid conditions it returns 1.
				return 1; 
		}
	
	public static void main(String[]args) {
		
		Scanner sc=new Scanner(System.in);
		System.out.print("Enter the number: ");
		int a=sc.nextInt();
		
		if(a==0) {
			System.out.println(1);
		}
		
		else {
			int b=findDigit(a);
			System.out.print(b);
		}
		sc.close();
	}
}

This version of code calculates digit number of zero as zero.

Recursion

public class FindingDigitsExample {

	public static int findDigit(int number) { //Recursive functions can not have void.
		
		int digit=0;
		
		if(number!= 0) {
			digit++;
			return findDigit(number/10);
		}
		
		else {		
			return digit;
		}
	}
	
	public static void main(String[]args) {
		
		int a=findDigit(124); 
		System.out.println(a);
		
	}
}

• When the main method run, it always gives zero.
