Create a game in Java console - CapitalFinder [Advice & Help]

Question

I would like to create a game in java, and I would like your advice: I explain you the goal as simply as possible:

• It's a game that takes place with the IDE console only

The goal is to define a number of capitals to find : If the player choose 20 capitals, A table will be filled in beforehand (or not if I can find a simpler way other than linking X countries to capitals by hand (if this is the case I don't know how to do it so if you have explanations I'm a taker)

In the table 20 will be drawn at random to avoid that it is all the time the same, the goal being to answer a maximum of answers, with a timer to beat his record

Questions : According to you, should I use a table that I fill by hand with countries & by linking them to capitals? If yes, how? (I tried with: collection/array unfortunately I block on how to link them to capitals) Can I manage the display of countries / linked to capitals via an API (if yes which one?)

Do you have any suggestions to avoid my head on the design of this game?

Thank you in advance, I join you my current code which is that little filled because my tests were carried out but that little conclusive thus useless to show you this

package fr.antyss77.capitalfinder;

import java.util.ArrayList;

public class Utils {

    public static void country() {
        ArrayList<String> country = new ArrayList<>();
        country.add("France");
        country.add("Jordanie");
        country.add("Pays-Bas");
        country.add("Turquie");
        country.add("Irak");
        country.add("Thailande");
        country.add("Serbie");
        country.add("Madagascar");
        country.add("Maroc");
        country.add("Canada");
        country.add("Italie");
        country.add("Chili");
        country.add("Bahamas");
        country.add("Grèce");
        country.add("Espagne");
        country.add("Belgique");
        country.add("Cuba");
        country.add("Mexique");
        country.add("Inde");
    }

    public static void question() {
    }

    public static void capital() {
    }

    public static void points() {
    }
}

Answer 1

There are several ways to connect the capital and the country.

1. Use Map

   public static void main(String[] args) {
       Map<String, String> countries = new HashMap<>();
       countries.put("country", "capital");
       System.out.println(countries.get("country"));
   }
   

2. Use two Lists, where capital and country have same indexes.

   public static void main(String[] args) {
       List<String> countries = new ArrayList<>();
       List<String> capitals = new ArrayList<>();
       countries.add("country");
       capitals.add("capital");
   
       System.out.println(capitals.get(countries.indexOf("country")));
   }
   

3. Create new class Country, which will have two fields: name and capital to store objects of this class in some collection

   class Country {
       String name;
       String capital;
   
       public Country(String name, String capital) {
           this.name = name;
           this.capital = capital;
       }
   }
   
   public static void main(String[] args) {
       List<Country> countries = new ArrayList<>();
       countries.add(new Country("country", "capital"));
   
       System.out.println(countries.get(0).name);
       System.out.println(countries.get(0).capital);
   }
