Java guessing game "Cannot resolve symbol"

Question

I am trying to make a guessing game where it generates a number from 1-9 and you have 4 guesses. Despite my best efforts im getting "Cannot resolve symbol" when i try to use randomNum after i initialized it in the start. // My first Java project so any help would be appreciated.

import java.util.Scanner;

public class GuessingGame {
    public static void main(String[] args) {

        int guess;
        int guesses = 0;
        Scanner input = new Scanner(System.in);
        for (int i = 0; i <= 0; i = i + 1) {
            int randomNum = (int)(Math.random() * 10);
            System.out.println("I have created a number 0-9 can u guess it?");
            System.out.println("You have 4 guesses");
        }
        while (guesses <= 4) {
            guess = input.next().charAt(0);
            if (guess == randomNum){
                System.out.println("You guessed it! the number was" + " " + randomNum);
            }
             else {
                System.out.println("Wrong!");
                guesses = guesses + 1;
                if(guesses > 4) System.out.println("U lost! the number was" + " " + randomNum);
            }
        }
        input.close();
    }
}
