猜数字游戏不起作用

Question

Apparently my code is not working according to an automated test and doesn't give me a pass for my solution, however when I run it it seems to work fine. I'm wondering what's wrong with my code?:

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

public class GuessingNumberGame {

    public static void main(String[] args) {
        Scanner reader = new Scanner(System.in);
        int numberDrawn = drawNumber();

        int i = 1;
        boolean correct = false;

        while (correct == false) {

        System.out.print("Guess a number: ");
        int guess = Integer.parseInt(reader.nextLine());

        if (guess == numberDrawn) {
            System.out.println("Congratulations, your guess is correct!");
            correct = true;

        } else if (guess < numberDrawn) {
                    System.out.println("The number is lesser, guesses made: " + i);
                                i++;
                    } else if (guess > numberDrawn) {
                        System.out.println("The number is greater, guess made: " + i);
                                    i++;
        }
        }
    }

    // DO NOT MODIFY THIS!
    private static int drawNumber() {
        return new Random().nextInt(101);
    }
}

It is exercise 41 on the University of Helsinki online Java course, the exercise details are here: http://mooc.cs.helsinki.fi/programming-part1/material-2013/week-2?noredirect=1#e41

The errors that I get are:

• If guess is too small, program should print "The number is greater".
• If guess is too large, program should print "The number is lesser".
• If the drawn number is 1 and user input is 0, 1, program should at first print "The number is greater", and after that "Congratulations, your guess is correct!"
• If the drawn number is 1 and user input is 2, 1, program should at first print "The number is lesser", and after that "Congratulations, your guess is correct!"

Thank you

You have simple logic mistake

When the number is lesser condition should be guess > numberDrawn or the number is greater it should be guess < numberDrawn :

    if (guess == numberDrawn) {
         System.out.println("Congratulations, your guess is correct!");
         correct = true;
    } else if (guess > numberDrawn) {
                System.out.println("The number is lesser, guesses made: " + i);           
                i++;
    } else if (guess < numberDrawn) {
                System.out.println("The number is greater, guess made: " + i);           
                i++;
    }
