Can't find symbol for user input

[nonny]

It worked earlier, but I don't know what i did to make it not work o-O
Check my code as well?

import java.util.*;
public class PP
{
   public static void main (String[] args) {
       Scanner myInput = new Scanner(System.in);
       System.out.print("Input an integer number: ");
       N = myInput.nextInt();
       System.out.println("The prime palindrome numbers are \n");
       myPrint(N);

   }
   
   public static void myPrint(int numPP){
       int count = 0;
       
        if(is_prime(N) && is_palindrome(N)){
            count++;
        }else
           System.out.println("There are no prime palindrome integer numbers");
    }
   
  
   public static boolean is_prime(int N){    
       if (N < 4){
           return true;
       }
       
       for (int i = 2; i <= N / 2; i++) {
           if (N % i == 0) {
               return false;
               }
        }
        return true;
    }    
               
    public static boolean is_palindrome(int N){
        int result = 0;
         
        while (N != 0){
            int rem = N%10;
            N = N/10;
            result = result*10+rem;
        }
        return true;
    }
}

maybe you ommited the decleration of N
