JAVA

Can someone explain how I would write the

public static List findFilmByTitle (String title) ? Im having a hard time understanding it.

public class DataSource final static String FILM_FILE final static String ACTORS_FILE final static String FILM-ACTORS-LINK-FILE = "film-actors, csV". "films.csv" "actors.csv" public static void init String realPath ServletUtils.getProjectInputFilesPath); FilmReader aReader -new FilmReader); List films aReader.readFilmFile(realPath, FILM_FILE) FilmCatalog filmInventory FilmCatalog.getInstance); filmInventory.addAll (films); ActorReader actorReader new ActorReader (); List actors actorReader. readActorFile(realPath, ACTORS_FILE) ActorInventory actorInventory-ActorInventory.getInstance); actorInventory.addAll (actors); FilmActorReader fiLmActorReader new FilmActorReader O; List > pairs- filmActorReader.readFilmActorFile(realPath, FILM_ACTORS_LINK_FILE); FilctorBuilder builder = new FilmActorBuilder (); builder.build(filmInventory, actorInventory, pairs); public static List findFi lmByTitle (String title) f // You will write this method using the Strategy pattern... return foundFilms
