Question

这是代码

package Question2;
import java.util.Scanner;
import java.util.Random;

public class PlayTheGame {
    public static void main(String[]args){

        Random randomNumber = new Random();
        int numberToGuess;
        int numberOfTries;
        int numberOfLimit=5;
        int UserInput;

        Scanner scan = new Scanner (System.in);
        int start =1;
        boolean winTracker =false;
        while(1==start){
            numberToGuess=randomNumber.nextInt(10);
            UserInput = 0;
            numberOfTries=0;
            System.out.println("Please guess the number between 1 and 10");
            while(numberToGuess!=UserInput && numberOfTries < numberOfLimit){
                UserInput=scan.nextInt();
                numberOfTries++;

                if (UserInput == numberToGuess){
                    System.out.println("You win!");
                    System.out.println("The guess number is "+numberToGuess+"and it's correct");
                    System.out.println("It took a total of "+numberOfTries+"guesses");
                }
If user has guessed in correctly, how to print the number that user input and tell the user that these are the numbers that you have input?

                else if (UserInput < numberToGuess){
                    System.out.println("Oppss..The number is too small");
                    System.out.println("Try next guess :");
                }

                else if (UserInput > numberToGuess){
                    System.out.println("Oppss..The number is too Highh");
                    System.out.println("Try next guess");
                }
            }

                if (numberToGuess!=userInput){
                    System.out.println("Oppss..You are out guess limitation!The correct number is : "+numberToGuess);
                }
        }
    }
}

如何在猜谜游戏中打印出用户输入的数字？任何帮助将不胜感激。

Answer 1

由于UserInput实际上是用户输入的内容，因此只需像其他任何内容一样打印。

   else if (UserInput < numberToGuess){
System.out.println("You have guessed: "+UserInput);   // <------ prints the user's choice
System.out.println("Oppss..The number is too small");
System.out.println("Try next guess :");
}

///在您的评论之后编辑

每次用户输入数字时，请将其存储在arraylist中。

ArrayList <Integer> inputs = new ArrayList();

然后每当用户输入一个数字时，

inputs.add(UserInput);

当该人获胜时，只需将其打印出来即可。

for(int i=0; i<inputs.size(); i++){
     System.out.print(inputs.get(i) + ",");
 }

以下是代码的外观：

ArrayList <Integer> inputs = new ArrayList();
Scanner sc = new Scanner(System.in);
int UserInput = sc.nextInt();

    .... code
else if (UserInput < numberToGuess){    // lets say the person got the number wrong, add to the list
inputs.add(UserInput);
 System.out.println("You have guessed so far: "+ inputs);
System.out.println("Oppss..The number is too small");
System.out.println("Try next guess :");
}

Answer 2

一种方法是添加列表

ArrayList<Integer> guessesSoFar = new ArrayList<>();

然后在numberOfTries++;添加此

之后

guessesSoFar.add(userInput);

然后输出

System.out.println("Guesses so far: " + Arrays.toString(guessesSoFar.toArray()));

PS。在userInput;）
