Stuck in main function. countDigit function is right but code is showing error

#1

import java.util.*;
public class Main {
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int d = sc.nextInt();
System.out.println(countDigit(n,d));
}

public static int countDigit(int n,int d){
    int count = 0;
	while(n !=0){
		int rem = n%10;
		if(rem == d){
			count++;
		}
		n = n/10;


	}
}

}

@discobot in the countDigit Function you are not returning anything but since you have specified int as return type you need to return an int.
correct CountDigit Funciton // Return count;

public static int countDigit(int n,int d){
    int count = 0;
	while(n !=0){
		int rem = n%10;
		if(rem == d){
			count++;
		}
		n = n/10;

	}
return count;
}
