猜谜游戏0-100 java

我有一个代码需要设置为0-100,并且有可能将零设为正确的答案.我将我的最终整数设置为MAX(100)/ MIN(0).但是0永远不是正确的答案.我有4年的编码经验,并且有2年的Java经验,但是似乎任何问题1-100或1-任何其他MAX都可以.请提供帮助,或说明是否不允许使用0.

import java.util.Random;
import java.util.Scanner;

public class GuessingGame {

    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);
        Random generator = new Random();

        int MIN = 0;
        int MAX = 100;
        int answer;
        int guess;
        String another = "y";
        boolean flag = false;
        boolean anotherFlag = true;

        while(anotherFlag){
            answer = generator.nextInt(MAX) + 1;

            System.out.println("I'm thinkin of a number between 0 and " + MAX );
            System.out.println("Can you guess what it is? n");
            flag = false;
            while(!flag) {
                guess = scan.nextInt();

                if(guess == answer){
                    System.out.println("You guessed correctly");
                    flag = true;

                } else{
                    System.out.println("That was wrong,try again.");
                }
            }

            System.out.println("Want to Play again?(y/n)");
            another = scan.next();

            if(another.equalsIgnoreCase("y") == true){
                anotherFlag = true;
            } else{
                anotherFlag = false;
            }
        }

谢谢您的帮助.
