如何根据用户输入选择ArrayList？

Question

我想让程序根据我的扫描仪输入从ArrayList中进行选择。比如，我写早餐和甜食，它必须随机列出早餐甜食，并打印随机索引。

我还在学习Java，我只是在玩，并试图编码小项目来训练它。

import java.util.ArrayList;
import java.util.Random;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        // program begins here, you get asked what kind of lunch you want to eat
        // after asking for the meal type and answering it, it goes to the next question

        System.out.println("Hi, welcome to Recipe-Randomizer! What kind of meal do you want, breakfast, lunch or maybe dinner?");
        System.out.print("Type one of the give choices now: ");
        String mealType = scanner.nextLine();
        System.out.print("So you want to eat for " + mealType + ". Do you want to eat some sweet or savory " + mealType + "?\nType in one of the given choices: ");
        String flavor = scanner.nextLine();
        System.out.println("A " + flavor + " " + mealType + "? Well, let's see what we have here.\nI am going to pick a random recipe.\nPlease wait...");


        // list of meals, list name describes
        ArrayList<String> breakfastSweet = new ArrayList();
        

        ArrayList<String> breakfastSavory = new ArrayList();

        ArrayList<String> lunchSweet = new ArrayList();
        

        ArrayList<String> lunchSavory = new ArrayList();
        

        ArrayList<String> dinnerSweet = new ArrayList();
        

        ArrayList<String> dinnerSavory = new ArrayList();
       

        GetRandomFromList.outputMeal(mealType, flavor, dinnerSavory); // doesn't make sense to put the list already in, I want it to automatically select the right list.

    }
}

下面是我已经写过的课程：

import java.util.ArrayList;
import java.util.Random;

public class GetRandomFromList {

    private static String randomList(ArrayList<String> list) {
        Random rand = new Random();
        return list.get(rand.nextInt(list.size()));

    }

    public static void outputMeal(String mealType, String flavor, ArrayList<String> list){ // the list should be chosen automatically, so my code doesn't work as I want it to work
        if (mealType.equals("breakfast") && flavor.equals("sweet")){
            System.out.println("What about " + GetRandomFromList.randomList() + "?");
        }
    }
}

我是否可以将列表存储在变量中，可能是这样的：

if (mealType.equals("breakfast") && flavor.equals("sweet")){
            // here make a variable of the breakfastSweet list
}

我知道很难理解我，但英语不是我的主要语言，希望它能被理解。
