Is there anyway to match answers and questions in String array

I am trying to code a word game. There are questions which is shown randomly and user try to answer right.

I matched questions and answers with switch case but I can't check if it is right or not because I can't figure out how can I find words in String array. Also, there is an error in the switch-case because of the method.

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;
        }
    }


 }

public static String [] array(String [] question) {




question[0]="A beverage which is white and generally consumed in mornings";
question[1]="The natural satellite of earth";
question[2]="An adjective which describes people who have not adequate money";
question[3]="A furniture sit around for eating or studying";

 }


 public static String[] equalM(String a1, String[] answer) {


for (int i=0; i<answer.length; i++) {
    if(a1.equals(answer[i])) {
        System.out.println("Correct you gained 500 points");
    } else 
        System.out.println("Wrong.You lost 500 points");
