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
|
||||||

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
|
||||||
|
|
||||||
```
