Question

因此，我正在编写一个简单的游戏，其中计算机猜测您正在考虑的数字在1到1000之间。无论我何时告诉计算机，无论我说更高还是更低，无论何时我运行此代码，代码都如下所示：它永远不会更新最小值和最大值以缩小答案的范围，对我来说逻辑看起来很正确。：

package com.company;
import java.util.*;



public class Main {

    public static void main(String[] args) {
        //set and initialize variables
        int currentGuess;
        int min = 0;
        int max = 1000;
        boolean guessedCorrectly = false;
        String userInput;
        Random rand = new Random();

        //Create user input object
        Scanner user_input = new Scanner(System.in);

        //Explain Game Rules to User
        System.out.println("Please think of a number and I will try to guess it.");
        System.out.println("You can respond h for higher, l for lower, and c for correct: ");

        //Main Game Loop
        while (guessedCorrectly == false){
            currentGuess = min + rand.nextInt(max - min + 1);
            System.out.print("Is your number " + currentGuess);
            userInput = user_input.next();
            if (userInput == "h"){
                min = currentGuess;
            }else if (userInput =="l"){
                max = currentGuess;
            }else if (userInput == "c"){
                guessedCorrectly = true;
            }else{
                System.out.println("Please enter an h for higher, l for lower, or c for correct ");
            }


        }
        System.out.println("Congratulations to MEEEEEE, I guessed it correctly!");
    }
}

有什么想法吗？

Answer 1

更改是否检查字符串的值是否等于引用而不是引用：

"l".equals(userInput)

数字求解游戏未更新随机数的上限和下限... Java
