Как я могу распечатать несколько классов в arraylist

---

I'm a first grader of a software engineering study and I have some trouble with a showcase I have to make. I give you a quick rundown of my project.

I don't know if anyone is familiar with the game Clash Royal? Its a game based on getting higher in trophies and collecting cards. And each arena unlocks new cards.

I want to make a deck builder. Where you can select 8 cards, and I calculate the average elixer cost. I want a function that can display all the cards available for your trophy range, and a function to see what cards you have unlocked in the arena you are at.

With that out of the way, let me explain my problem: I made a Superclass: Card, and the classes Troop, Spell, DefBuilding, and PassiveBuilding extend on that superclass. After that,

Then I made a Class: Arena, and in my main, I wanna declare al the arena's. The thing I am struggling with is the fact that I don't know how I can print all the cards in a vector of the matching Arena. In 1 arena you have multiple classes, for ex. you have spells and troops in the arraylist.

So the actual question is as follow: How can i print out a list of all the cards that are in that arraylist, showing the name and elixer (only the attributes in the superclass Card).

MAIN:

package logic;

import data.Arena;
import data.Card;
import data.Spell;
import data.Troop;

import java.util.ArrayList;

public class Main {

    public static void main(String[] args) {

        /* Create Arena's */
        Arena trainingCamp = new Arena("Training Camp", 0, 0);

        /* Create Cards Arena 1 */
        Card arrow = new Spell("Arrows", 3, 243, 86, 4);
        Card minions = new Troop("Minions", 3, 84, 84, 190, 2, 1, "Medium", 0, 3);

        /* Create ArrayList Arena 1 */
        ArrayList<Card> trainingCampList = new ArrayList<>();

        /*Put cards in the arraylist*/
        trainingCamp.getTrainingCampList().add(arrow);
        trainingCamp.getTrainingCampList().add(minions);

        /*Print cards out on the screen*/
        for (Card card : trainingCampList) {
            System.out.println(card.toString());
        }

ARENA:

package data;

import java.util.ArrayList;

public class Arena {
    private String name;
    private int minTrophies;
    private int maxTrophies;

    public Arena(String name, int minTrophies, int maxTrophies) {
        this.name = name;
        this.minTrophies = minTrophies;
        this.maxTrophies = maxTrophies;
    }

    ArrayList<Card> trainingCampList = new ArrayList<>();

    public ArrayList<Card> getTrainingCampList() { return trainingCampList; }

    public void setTrainingCampList(ArrayList<Card> trainingCampList) {
        this.trainingCampList = trainingCampList;
    }
}

CARD:

package data;

public class Card {
    private String name;
    private int elixer;

    public Card(String name, int elixer) {
        this.name = name;
        this.elixer = elixer;
    }

    @Override
    public String toString() {
        return "Card{" +
                "name='" + name + '\'' +
                ", elixer=" + elixer +
                '}';
    }
}

TROOP:

package data;

public class Troop extends Card {
    private int dammage;
    private int dammagePerSecond;
    private int hitpoints;
    private double range;
    private double hitSpeed;
    private String speed;
    private int deathDammage;
    private int count;

public Troop(String name, int elixer, int dammage, int dammagePerSecond, int hitpoints, double range, double hitSpeed, String speed, int deathDammage, int count) {
        super(name, elixer);
        this.dammage = dammage;
        this.dammagePerSecond = dammagePerSecond;
        this.hitpoints = hitpoints;
        this.range = range;
        this.hitSpeed = hitSpeed;
        this.speed = speed;
        this.deathDammage = deathDammage;
        this.count = count;
    }

}

SPELL:

package data;

public class Spell extends Card{

    private int dammage;
    private int crowTowerDammage;
    private double radius;

public Spell(String name, int elixer, int dammage, int crowTowerDammage, double radius) {
        super(name, elixer);
        this.dammage = dammage;
        this.crowTowerDammage = crowTowerDammage;
        this.radius = radius;
    }
}

Что я уже пробовал:

The last ting I tried was to add a to a to string method in my class card that to print out the name and elixer. I only put 1 Troop card and 1 spell Card in the list to see if it should word. But if failed.

I got no errors, so i dont know what i am doing wrong :(

NOTE: I only put the classes of Spell and Troop in the question, i dont need the other classes. If i can make this work. I can do it for all the classes.
