Question

import java.util.Scanner;
public class guessGame {
    public static void main(String[] args){
        String ansOne;
        String ansTwo;
        String result="";

        Scanner sc = new Scanner(System.in);
        System.out.println("TWO QUESTIONS!");
        System.out.println("Think of an object and I'll try to guess it");
        System.out.println("Qusetion 1) Is it a animal,vegetable or mineral?  ");
        ansOne = sc.next();
        System.out.println("Qusetion 2) Is it bigger than a bread box");
        ansTwo = sc.next();

        if(ansOne == "animal" && ansTwo == "yes"){
            result = "Squirrel";
        }
        else if( ansOne == "animal" && ansTwo == "no"){
            result = "moose";
        }
            else if( ansOne == "Vegetable" && ansTwo == "Yes"){
            result = "carrot";
        }
            else if( ansOne == "Vegetable" && ansTwo == "no"){
            result = "Watermelon";
        }
            else if( ansOne == "mineral" && ansTwo == "Yes"){
            result = "Paper clip";
        }
            else if( ansOne == "mineral" && ansTwo == "no"){
            result = "Camero";
        }
        System.out.println("My guess is that You are thinking of a " +result);
        System.out.println("I would ask you if I'm right,but I don't actually care...");  
    }  
}

在上面的代码中，我想显示结果。但它没有显示，我得到以下输出：

两个问题！想想一个物体，我会试着猜测它问题1）它是动物，植物还是矿物质？蔬菜问题2）它是否比面包盒大是我的猜测是你在想一个人我会问你我是否对，但我实际上并不关心...

Answer 1

我认为你应该使用sc.nextLine（）而不是sc.next（）。另外使用equals（）而不是'=='

Answer 2

您必须将您的字符串与equals（）进行比较

E.g。 String1.equals（＆＃34; LALALA＆＃34）;

如果使用==进行比较，您将获得意想不到的结果。

我的代码没有显示存储在变量中的字符串
