 > An analogous real-world example of the Presentation Model design pattern is the relationship between a scriptwriter, an actor, and a director in a theater production. The scriptwriter creates the script (analogous to the business logic), which the actor then interprets and performs on stage (analogous to the user interface). The director acts as the intermediary, ensuring that the actor's performance aligns with the script and the vision of the play (similar to the Presentation Model coordinating the UI and the business logic). This separation allows the script to be rewritten without changing the actor's techniques or the director's interpretation, ensuring flexibility and maintainability.

 First, we have the `Album` class. This class represents the data model in our application. It contains properties like `title`, `artist`, `isClassical`, and `composer`.
 
 ```java
+@Setter
+@Getter
+@AllArgsConstructor
 public class Album {
     private String title;
     private String artist;
     private boolean isClassical;
     private String composer;

-    public Album(String title, String artist, boolean isClassical, String composer) {
-        this.title = title;
-        this.artist = artist;
-        this.isClassical = isClassical;
-        this.composer = composer;
-    }
-
-    // getters and setters...
 }
 ```
 
 Next, we have the `DisplayedAlbums` class. This class is responsible for managing a collection of `Album` objects.
 
 ```java
+@Slf4j
+@Getter
 public class DisplayedAlbums {
-    private List<Album> albums;
+    private final List<Album> albums;
