Netflix Database
In this program, you will build a Netflix movie database usingthe provided file, netflix.csv. The file contains more than twohundred records of movies and TV programs, with each recordconsisting a title, a rating, a release year, and a user ratedscore.
There are three classes that you will need to implement: Movie,NetflixHandler, and NetflixApp.
Class: Movie
|
Movie |
|
– title: String – rating: String – year: int – score: int |
|
+ Movie (String title, String rating, int year, int score) + getTitle(): String + getRating(): String + getYear(): int + getScore(): int + toString(): String |
Instance variables:
- title: Title of a movie or TV program.
- rating: Rating of a movie or TV program. E.x.: R or PG-13
- year: Year of release.
- score: User rated score.
Methods:
- Movie (String title, String rating, int year, int score): Anoverloaded constructor.
- Getters for all the instance variables.
- toString(): It returns a string of information: title yearrating score
Class: NetflixHandler
|
NetflixHandler |
|
– data: Movie[] – actualSize: int + SIZE: int = 500 |
|
+ NetflixHandler () + read (String filePath): void + displayAllMovies (): void + searchTitle (): void + searchYear (): void + sort (Movie[] movies, int size): void + makeRecommendations(): void |
Instance variables and constants:
- data: It is an array of Movie objects.
- actualSize: It is the real number of Movie objects in apartially filled array.
- SIZE: A constant that is set to be 500.
Methods:
- NetflixHandler (): The default constructor that initializes theinstance variable, data, to a Movie array that has a size of500.
- read (): This method opens the given file, netflix.csv, andreads it. While reading the file line by line, it also creates aMovie object and saves it into data.
- displayAllMovies (): This method loops through all the Movieobjects saved in data and display their information.
- searchTitle (): This method looks for a movie that matches thetitle provided by a user.
- searchYear (): This method looks for a group of movies thatmatch the release year given by a user.
- sort (Movie[] movies, int size): This method sorts a givenMovie array, movies, using the provided size. It sorts the arrayinto a descending order based on the user rated score.
- makeRecommendations (): This method makes recommendations to auser based on two options. Option one: It finds thetop-5 movies, based on the user rated score, undera certain rating. The method then writes those 5 movies into afile, “top_5_movies.txt”. Option two: It finds thetop-20 movies, based on the score only. The methodthen writes those 20 movies in to a file, “top_20_movies.txt”.
Class: NetflixApp
This is the main class. It has a private andstatic method, menu, which displays a menu that containsseveral choices (Please see the expected outcomes file for moredetails.). The main method should create a NetflixHandler objectand let it call the read method before taking any choices.
