我如何正确地将此值传递给main？

Question

我无法将“猜测”的值传递到我的主要方法中。 试图返回猜测的方法在main中只显示为零。我尝试了各种方法，例如void方法和不同的返回值，但是即使从主对象的while循环中，guess值也不会更新我看到，应该从方法中更新它，并将其传递给它下面的猜测。

import java.util.*;
public class assignment052 {
  public static void main(String[] args) {
    Scanner console = new Scanner(System.in);
    int userGuess = 0;
    int compNum = 0;
    int guess = 0;
    int totalGuesses = 0; //
    int best = 9999; //
    introduction();

    int games = 0;

    String playAgain = "y";
    while(playAgain.equalsIgnoreCase("y")) {
     System.out.println();
        System.out.println("I'm thinking of a number between 1 and 100...");
        games++;
        guessNumber(console, userGuess, compNum, guess);
     System.out.println(guess);
     totalGuesses += guess;
        System.out.println("Do you want to play again?");
        Scanner newGame = new Scanner(System.in);
        playAgain = newGame.next();

     if (best > guess) { // 
        best = guess; // 
        }

    }
    result(games, totalGuesses, best);

}
// Method that introduces the game
public static void introduction() {
    System.out.println("This program allows you to play a guessing game.");
    System.out.println("I will think of a number between 1 and");
    System.out.println("100 and will allow you to guess until");
    System.out.println("you get it.  For each guess, I will tell you");
    System.out.println("whether the right answer is higher or lower");
    System.out.println("than your guess.");
}

// method to play 1 game
public static double guessNumber(Scanner console, int userGuess, int compNum, int guess) {
    Random rand = new Random();
    userGuess = console.nextInt();
    guess = 1;
    compNum = rand.nextInt(100)+1;
    while(compNum != userGuess) {
     if(compNum > userGuess) {
            System.out.println("It's higher.");
        } else {
            System.out.println("It's lower.");
        }
        guess++;
        userGuess = console.nextInt();
    }
    System.out.println("you got it right in " + guess + " guesses");
  return guess;
}
// method for overall result

public static void result(int games, int totalGuesses, int best) {
  System.out.println("Overall results:");
  System.out.println();
  System.out.println("Total games played : " + games);
  System.out.println("Total guesses : " + totalGuesses);
  System.out.println("Guesses per game : " + totalGuesses / games);
}
