猜一个范围内的随机数的Java程序

编写一个程序，生成一个随机数，并要求用户猜数字是什么。如果用户的猜测值高于随机数，程序应显示Too high, try again 。如果用户的猜测值低于随机数，程序应显示Too low, try again 。程序应该使用一个循环，直到用户正确猜出随机数为止。

Input: 15 (a random value that is not known before)
Output: Guess a number between 1 and 100: 
1
Too low, try again
Guess a number between 1 and 100: 
10
Too low, try again
Guess a number between 1 and 100: 
25
Too high, try again
Guess a number between 1 and 100: 
20
Too high, try again
Guess a number between 1 and 100: 
15
Yes, you guessed the number.

import java.util.Scanner;
  
public class GFG {
    public static void main(String[] args)

        // stores actual and guess number

        // Random instance
        Random rand = new Random();
  
        boolean correct = false;
  
        // correct answer
        answer = rand.nextInt(MAX) + 1;
  
        // loop until the guess is correct
        while (!correct) {
  
            System.out.println(

            // guess value
            guess = in.nextInt();
  
            // if guess is greater than actual
            if (guess > answer) {
                System.out.println("Too high, try again");
            }
  
            // if guess is less than actual
            else if (guess < answer) {

                    "Yes, you guessed the number.");
