Java:代码工作不正确 [英] Java: Code ain't working the right way

问题描述

首先，您必须知道我是 Java 的菜鸟，我刚开始编写代码，它是我的第一门编程语言.所以如果我开始有点愚蠢，请不要生气，我只是想学习编码 - 谢谢

我正在尝试制作一个简单的猜谜游戏"，但我的代码没有等待用户输入.请帮帮我，我不知道该怎么办.

I'm trying to make a simple " guessing game ", but my code aren't waiting for the user-input. please help me, I don't know what to do.

我的代码:

    public static void main(String[] args)
    {
        //Creating the scanner
        @SuppressWarnings("resource")
        Scanner input = new Scanner(System.in);


        //Creating the two random numbers.
        Random rand = new Random();
        int userNumber  = rand.nextInt(10) + 1;
        int comNumber = rand.nextInt(10) + 1;


         //Asks the user what to do.
        System.out.println("Your number is: " + userNumber +" of 10");
        System.out.println("Do you think that your number is Heigher(H), Lower(L) or Equal To(E) the computers number");


            //Checking if the user is right.

        //If the user types in LOWER
        if(userNumber < comNumber && input.equals("L"))
            System.out.println("You are right. The computer's number is: " + comNumber);
        if(userNumber < comNumber && !input.equals("L"))
            System.out.println("You are wrong. The computer's number is: " + comNumber);

        //If the user types in EQUAL TO.
        if(userNumber == comNumber && input.equals("E"))
            System.out.println("You are right. The computer's number is: " + comNumber);
        if(userNumber == comNumber && !input.equals("E"))
            System.out.println("You are wrong. The computer's number is: " + comNumber);

        //If the user types in HEIGHER.
        if(userNumber > comNumber && input.equals("H"))
            System.out.println("You are right. The computer's number is: " + comNumber);
        if(userNumber > comNumber && !input.equals("H"))
            System.out.println("You are wrong. The computer's number is: " + comNumber);

        else
            System.out.println("You can only type in ' L ', ' E ' or ' H '.");




    }
}

如果您能帮我解决我的问题，我会很高兴，并告诉我如何删除 @SuppressWarnings("resource")/解释为什么它必须在那里.>

推荐答案

您使用的 Scanner 是错误的.您需要调用 scanner.nextLine() 从用户那里获取输入(一个字符串)，你需要将字符串转换为整数(使用 Integer.parseInt) 进行比较它与其他整数.

You're using Scanner wrong. You need to call scanner.nextLine() to get input (a String) from the user, and you need to convert the String to an integer (with Integer.parseInt) to compare it with other ints.
