Question

我正在尝试编写文字游戏。有些问题是随机显示的，用户会尝试正确回答。

我用开关大小写匹配了问题和答案，但由于无法弄清楚如何在String数组中找到单词，所以无法检查它是否正确。同样，由于该方法，开关盒中也存在错误。

import java.util.Scanner;

import java.util.Random;

public class Odev {

public static void main(String[] args) {

    Scanner input= new Scanner(System.in);
    System.out.println("Enter the 1 for answer or 2 for requesting a letter.");


    int first= input.nextInt();
    String[] question = new String[9];
    String [] answer=new String[9];
    question=array(question);
    answer=array2(answer);
    Random b= new Random();
    int randomNumber=b.nextInt(question.length);


    if(first==1) {
        System.out.println(question[randomNumber]);

        System.out.println(randomNumber);
        String a1=input.next();
        switch (randomNumber) {
        case 0: equalM(a1, answer[0]);

        break;
        case 1: equalM(a1, answer[1]);

        break;
        case 2:equalM(a1, answer[2]);

        break;
        case 3:equalM(a1, answer[3]);

        break;
        case 4:equalM(a1, answer[4]);

        break;
        case 5:equalM(a1, answer[5]);

        break;
        case 6:equalM(a1, answer[6]);

        break;
        case 7:equalM(a1, answer[7]);

        break;
        case 8:equalM(a1, answer[8]);
        break;
        }
    }


}

您可以使用哈希图轻松完成此操作，但是如果您要坚持使用数组，则可以打印出所有答案选项及其索引号，然后读取用户键入的数字以获取正确答案。然后，您只需检查该数字是否等于用于生成问题的随机数即可。
