Homework - Calling method into main

I am new to Java and trying to create a program that is a guessing game. The user inputs a number 1-20. The program tells the user if it is correct or not. The method giveHint() must display a hint but not return a value. The program must keep asking the user to try again until it is correct. I am not sure how to call the method into the main. Any help or advice would be appreciated. I thank you for your time.

Code:

package guessinggame;
import java.util.Scanner;

public class GuessingGame {


    public static void giveHint(int guess,int answer) {
             
        if (answer < guess){
            System.out.println("Incorrect! \n Hint: Try a higher number");
            
        }
        else if (answer > guess){
            System.out.println("Incorrect! \n Hint: Try a lower number");
            
        }
    }    
  
    public static void main(String[] args) {
        
        int guess;
        int answer;
        
        Scanner my_input = new Scanner(System.in);
        answer = (int)(Math.random()*20) + 1;
        System.out.println("Enter a number between 1 and 20");
        guess = my_input.nextInt();
        if (answer == guess){
            System.out.println("Correct!");
            }      
      else if (answer < guess || answer > guess) {
          //This is where I need to import the giveHint() method 
             }
    } 
      
     
    
}

Here is my current progress. I just cant seem to get it to compile thought. Thoughts?

Code:

package guessinggame;
import java.util.Scanner;

public class GuessingGame {

         public static void main(String[] args) {
        
        int guess;
        int answer;
        
        Scanner my_input = new Scanner(System.in);
        answer = (int)(Math.random()*20) + 1;
        System.out.println("Enter a number between 1 and 20");
        guess = my_input.nextInt();
            if (answer == guess){
            System.out.println("Correct!");
            }      
            else  {
            giveHint();
             }
    } 
      
        public static void giveHint(int answer, int guess) {
             
        if (answer < guess){
            System.out.println("Incorrect! \n Hint: Try a higher number");
            
        }
        else if (answer > guess){
            System.out.println("Incorrect! \n Hint: Try a lower number");
            
        }
    }   
        
    
}

Thanks NormR, but I think I got it. I am not receiving errors. Here is my code:

Code:


package guessinggame;
import java.util.Scanner;

public class GuessingGame {

   public static void giveHint(int answer, int guess) {             
        if (answer < guess){
            System.out.println("Incorrect! \n Hint: Try a lower number.");            
        }
        else if (answer > guess){
            System.out.println("Incorrect! \n Hint: Try a higher number.");            
        }
    } 
   
   public static void main(String[] args) {        
        int guess;
        int answer;        
        Scanner my_input = new Scanner(System.in);
        answer = (int)(Math.random()*20) + 1;
            System.out.println("Enter a number between 1 and 20");
        guess = my_input.nextInt();
            while (guess!=answer) {
        giveHint(answer,guess);
        guess = my_input.nextInt();
             }
            if (answer == guess){
            System.out.println("|***** CORRECT! *****|");
            }
    } 
      
               
    
}
