Hola Franco, como estas?

Resolvi el ej de manera parecida que la sol, pero creando comparadores estaticos en la clase TVEpisode. Queria saber si eso es correcto, o si deberia si o si estar en TVSeason. Gracias

package ej1;
import java.time.LocalDate;
import java.util.Comparator;

public class TVEpisode implements Comparable<TVEpisode>{
   private final int id;
   private final String title;
   private final double rating;
   private final LocalDate airedDate;

   public TVEpisode(int id, String title, double rating, LocalDate airedDate) {
       this.id = id;
       this.title = title;
       this.rating = rating;
       this.airedDate = airedDate;
   }

   public int getId() {
       return id;
   }

   public String getTitle() {
       return title;
   }

   public double getRating() {
       return rating;
   }

   public LocalDate getAiredDate() {
       return airedDate;
   }

   @Override
   public int compareTo(TVEpisode ep2){
       return Integer.compare(this.getId(), ep2.getId());
   }


   static public Comparator<TVEpisode> getDateComp(){
	return new Comparator<TVEpisode>(){
		@Override
		public int compare(TVEpisode o1, TVEpisode o2){
			int aux = o2.getAiredDate().compareTo(o1.getAiredDate()); 
			if(aux == 0){
				return o1.compareTo(o2); // asc
			}
			return aux;
		}
	};
   }
   static public Comparator<TVEpisode> getRankingComp(){
	return (o1,o2)->{
		int aux = Double.compare(o2.getRating(), o1.getRating());
		if(aux == 0){
			return o1.compareTo(o2);
		}
		return aux;
	};
   }

   static public Comparator<TVEpisode> getNameComp(){
	return (o1,o2)->{
		int aux = o1.getTitle().compareTo(o2.getTitle());
		if(aux ==0){
			return o1.compareTo(o2);
		}
		return aux;
	};
   }

   @Override
    public String toString(){
       return "(%d) Episode %s aired on %s has a rating of %.2f".formatted(id, title, airedDate.toString(), rating);
   }
}

package ej1;
import java.util.Arrays;
import java.util.Comparator;

public class TVSeason{
	private final TVEpisode[] array;
	
	public TVSeason(TVEpisode[] arr){
		array = arr;
	}
	private TVEpisode[] getVec(Comparator<TVEpisode> cmp){
		TVEpisode[] rta = Arrays.copyOf(array, array.length);
		Arrays.sort(rta, cmp);
		return rta;
	}	
	public TVEpisode[] getDateOrderCopy(){
		return getVec(TVEpisode.getDateComp());
	}
 	public TVEpisode[] getNameOrderCopy(){
                return getVec(TVEpisode.getNameComp());
        }
 	public TVEpisode[] getRatingOrderCopy(){
                return getVec(TVEpisode.getRankingComp());
        }
}

Hola @lulostupnik Está perfecto así.
