## Bonus Tasks ✒️ ## Bonus Tasks ✒️
1. Fetch and display movie information using movie ID 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) - genres (List<Genre>) - List of genres
- Print formatted output (see example below)
- images (String) - Poster image URL
- country (String) - Production country
- imdbRating (String) - IMDB rating
Implementation Steps:
- Build and Send Request (getMovieById method):
- Create HTTP request to: https://api.meshcomp.ir/api/v1/movies/{movieId}
- 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
### Example Output:
