 ## Bonus Tasks ✒️
 1. Fetch and display movie information using movie ID
 
-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.
+Implement movie search by ID. User enters an ID, program displays complete movie details.
 
-Movie Class Fields (already defined):
+### ⚠️ First: Add Missing Fields to Movie Class
+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`
 
-- id (Long) - Movie identifier
+### Implementation Steps:
 
-- title (String) - Movie title
+1. **Complete `getMovieById(movieId)`**
+   - Build request to: `https://api.meshcomp.ir/api/v1/movies/{movieId}`
+   - If status 200 → return JSON body, else → return null
 
-- year (String) - Release year
+2. **Complete `displayMovieDetails(movieId)`**
+   - Call `getMovieById()` → check for null
+   - Use Gson to parse JSON to Movie object (after adding fields above)
+   - Print formatted output (see example below)
 
-- genres (List<Genre>) - List of genres
+### Example Output:
-
+```
-- images (String) - Poster image URL
+           =======================================================================
-
+                               THE SHAWSHANK REDEMPTION (1994)
-- country (String) - Production country
+           =======================================================================
-
+           Rating: 9.3/10  |  Votes: 1,738,596
-- imdbRating (String) - IMDB rating
+           Director: Frank Darabont
-
+           Cast: Tim Robbins, Morgan Freeman, Bob Gunton, William Sadler
-Implementation Steps:
+           Genre: Crime, Drama
-
+           Runtime: 142 min  |  Rated: R
-- Build and Send Request (getMovieById method):
+           Country: USA  |  Released: 14 Oct 1994
-
+           Plot: Two imprisoned men bond over a number of years, finding
-      - Create HTTP request to: https://api.meshcomp.ir/api/v1/movies/{movieId}
+           solace and eventual redemption through acts of common decency.
-
+           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

-     * INSTRUCTIONS:
+        - Then use Gson to parse your json string
-     * 1. Call getMovieById(movieId) to get the JSON response
+     5. Print all movie details in a readable format
-     * 2. Check if response is null (if yes, print error and return)
+
-     * 3. Parse the JSON string to JsonObject (inside try-catch)
+     (PUT ALL PARSING CODE INSIDE THE EXISTING try-catch)
-     * 4. Extract all fields: id, title, year, genres array, poster, country, imdb_rating
-     * 5. Convert genres array to comma-separated string
-     * 6. Print all movie details in a readable format
-     *
-     * PUT ALL PARSING CODE INSIDE THE EXISTING try-catch
-     *
-     * @param movieId The ID of the movie to display
