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();
    }
}

I need to be able to assign every single question input to a new variable (questionOne, questionTwo, etc.). I would do the same thing for the answers and store both (questions and answers), in separate arrays.

Check out Javas ArrayList Type. You can store many Objects at runtime withe the list.add(obj); Method. This way you can store as Many questions as you like!
