如何让程序创建自己的变量以匹配（无限）用户输入？

Question

import java.util.Scanner;

public class Study {

public static void main(String[] args){

    System.out.println("Hello, welcome to Study Help v1.0!");
    try {
        Thread.sleep(2500);
    } catch (Exception e) {
        e.printStackTrace();
    }
    System.out.println("In this program we will help you study for an upcoming test or assessment!");
    System.out.println("Unfortunately, this version only works for a multiple choice test.");
    try {
        Thread.sleep(2500);
    } catch (Exception e) {
        e.printStackTrace();
    }
    System.out.println("Please input the number of questions that there will be for your studying.");

    int questions;

    Scanner userNumber = new Scanner (System.in);

    questions = userNumber.nextInt();

    System.out.println("You've chosen " + questions + " questions.");
    System.out.println("Now, add the questions to your study guide.");

    //This will later become a while loop (until their input numbers equal the amount of questions they said earlier)
    System.out.println("Input the full question number " + (questions-=questions-1)+ " now.");

    String userInput;

    Scanner userQuestion = new Scanner (System.in);

    userInput = userQuestion.nextLine();
    }
}

我需要能够将每个单个问题输入分配给新变量（questionOne，questionTwo等）。 我会对答案做同样的事情，并将两者（问题和答案）存储在单独的数组中。

查看Javas ArrayList类型。 您可以在运行时使用list.add(obj);存储许多对象list.add(obj); 方法。 这样，您可以存储尽可能多的问题！
