Question

我是java的新手，我有一个我在学校工作的项目。当我运行程序时，它给了我所要求的一切，除了它打印的事实＆＃34;数字更大＆＃34;在答案之上。有什么我想念的吗？感谢

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

public class Project {

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

        int numberOfGuesses = 0;
        int x = 0;

        Random rand = new Random();
        int randomNumber = rand.nextInt(100) + 1;

        while (x != 1) {
            System.out.print("Guess an integer between 1 and 100: " );
            int guessedNumber = reader.nextInt();
            if (guessedNumber < randomNumber) {
                System.out.println("The number is bigger");
            }
            if (guessedNumber > randomNumber) {
                System.out.println("The number is smaller");
            }
            else{
            x++;
            }
            numberOfGuesses++;
        }
        System.out.println("You're correct! It took" + " " + numberOfGuesses + " " + "guesses.");

        }
    }
}

Answer 1

onSubmit()

要

        if (guessedNumber < randomNumber) {
            System.out.println("The number is bigger");
        }
        if (guessedNumber > randomNumber) {
            System.out.println("The number is smaller");
        }
        else{
        x++;
        }

Answer 2

当数字越大时，你的第二个如果失败并转到其他部分，它将x递增到1并存在程序。将第二个if语句放在else if。

        if (guessedNumber < randomNumber) {
            System.out.println("The number is bigger");
        }
        else if (guessedNumber > randomNumber) {
            System.out.println("The number is smaller");
        }
        else{
        x++;
        }
