Question

I need help creating a code below

 

Write a recursive method called digitCount() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10.

Ex: If the input is:

345

the method digitCount() returns and the program outputs:

3

1 import java.util.Scanner;
2
3 public class LabProgram {
4
5
/* TODO: Write recursive digitCount() method here. */
6
7
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int num, digits;
8
91811231415 16
10
}
num scnr.nextInt ();
digits
digitCount (num);
System.out.println(digits);
