 ## Bonus Tasks ✒️
 1. Fetch and display movie information using movie ID
 
-Implement movie search by ID. User enters an ID, program displays complete movie details.
+In this section, you must implement the ability to search for a movie by its ID. The user enters an ID, and the program displays complete movie details.
 
-### ⚠️ First: Add Missing Fields to Movie Class
+Movie Class Fields (already defined):
-The API returns more data than your current class supports. Add these fields:
-- `actors`, `awards`, `director`, `imdb_id`, `imdb_votes`, `metascore`, `plot`, `rated`, `released`, `runtime`, `type`, `writer`
 
-### Implementation Steps:
+- id (Long) - Movie identifier
 
-1. **Complete `getMovieById(movieId)`**
+- title (String) - Movie title
-   - Build request to: `https://api.meshcomp.ir/api/v1/movies/{movieId}`
-   - If status 200 → return JSON body, else → return null
 
-2. **Complete `displayMovieDetails(movieId)`**
+- year (String) - Release year
-   - Call `getMovieById()` → check for null
-   - Use Gson to parse JSON to Movie object (after adding fields above)
-   - Print formatted output (see example below)
 
-### Example Output:
+- genres (List<Genre>) - List of genres
-```
+
-           =======================================================================
+- images (String) - Poster image URL
-                               THE SHAWSHANK REDEMPTION (1994)
+
-           =======================================================================
+- country (String) - Production country
-           Rating: 9.3/10  |  Votes: 1,738,596
+
-           Director: Frank Darabont
+- imdbRating (String) - IMDB rating
-           Cast: Tim Robbins, Morgan Freeman, Bob Gunton, William Sadler
+
-           Genre: Crime, Drama
+Implementation Steps:
-           Runtime: 142 min  |  Rated: R
+
-           Country: USA  |  Released: 14 Oct 1994
+- Build and Send Request (getMovieById method):
-           Plot: Two imprisoned men bond over a number of years, finding
+
-           solace and eventual redemption through acts of common decency.
+      - Create HTTP request to: https://api.meshcomp.ir/api/v1/movies/{movieId}
-           Awards: Nominated for 7 Oscars. Another 19 wins & 30 nominations.
+
-           =======================================================================
+      - Replace {movieId} with the ID from user
+
+      - Send request and get response
+
+- Handle Response (getMovieById method):
+
+      - If status code is 200, return JSON body
+
+      - Otherwise, print error and return null
+
+- Parse JSON and Create Movie Object (displayMovieDetails method):
+
+      - Parse JSON response to JsonObject
+
+      - Extract all fields: id, title, year, poster, country, imdb_rating
+
+      - Parse "genres" array and convert each to Genre object
+
+      - Create a Movie object with all extracted data
+
+- Display Results (displayMovieDetails method):
+
+      - Print all movie details in a clean format
+
+2. Advanced search (title, genre, year, rating, etc.)
+
+3. Sorting options for movies
+
+4. Save/load favorite movies to/from a file
+
+5. Improved console menu design
+
+6. GUI version using JavaFX
