Есть ли способ сопоставить ответы и вопросы в массиве String

Я пытаюсь закодировать словесную игру. Есть вопросы, которые отображаются случайным образом, и пользователь пытается ответить правильно.

Я сопоставил вопросы и ответы с помощью переключателя, но я не могу проверить, правильно это или нет, потому что я не могу понять, как мне найти слова в массиве String. Кроме того, в переключателе есть ошибка из-за метода.

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;
        }
    }


}
