Øvelse i swing.

Valgbaseret spil

// Der er 4 klasser indtil videre.

// Dette er den første klasse, som skal bruges til at initialisere alle "scenarierne" baseret på de valg man tager:

import java.util.HashMap;
/**
 * Lav en beskrivelse af klassen Scenarios her.
 * 
 * @author (dit navn her)
 * @version (versions nummer eller dato her)
 */
public class Scenarios
{
    private String scenario;
    private HashMap<String, Integer> allScenarios;
    
   public Scenarios(String scenario) {

       allScenarios = new HashMap<>();
       
    }
   
    
    
   public String getScenario() {
        return scenario;
    }
}

// Her er interfacen, som bliver brugt til at starte selveste programmet, og indeholder de vigtigeste informationer.
