Homework 2: Movie Database

Assignment

You are going to write 2 classes Movie.java and MovieDatabase.java.

Movie.java

The class represents movies. It has 4 private members:
Member variables

String title: title of the movie.
String[] directors : director(s) of the movie.
String[] casts: actors and actresses of the movie.
int year: the year that the movie released.

It has one public constructor:
Constructor

Movie(String title, String[] directors, String[] casts, int year): don't use shallow copying for the arrays.

It has several public methods:
Methods

boolean searchTitle(String keyword): search if the title contains the keyword.
boolean searchDirectors(String keyword): returns true if one of the director names contains the keyword.
boolean searchCasts(String keyword): returns true if one of the casts name contains the keyword
boolean search(Sring keyword) : returns true if either title, director names or cast names contain the keyword.
All the search method are not case sensitive. i.e, searchTitle("MATRIX") is same as searchTitle("Matrix")
If the movie name is "The Matrix", then searchTitle("trix") should return true because the word Matrix contains trix.

void showInfo(): show the information of the movie at the Dos Prompt. The format is like this

Title: The Matrix
Directors: Andy Wachowski, Larry Wachowski
Casts: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving
Year: 1999

Here are some sample outputs
Test1.java
To make sure that you are not using shallow copy.

public class Test1 {
    public static void main(String[] args) {
        String[] directors = {"Andy Wachowski", "Larry Wachowski"};
        String[] casts =  {"Keanu Reeves", "Laurence Fishburne","Carrie-Anne Moss", "Hugo Weaving"};
        Movie movie = new Movie("The Matrix",  directors,  casts,1999);
        movie.showInfo();
        // change one name of the directors
        directors[1] = "Charles Li";
        movie.showInfo();
    }
}

Output

Title: The Matrix
Directors: Andy Wachowski, Larry Wachowski
Casts: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving
Year: 1999
Title: The Matrix
Directors: Andy Wachowski, Larry Wachowski
Casts: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving
Year: 1999

Test2.java

public class Test2 {
    public static void main(String[] args) {
        String[] directors = {"Andy Wachowski", "Larry Wachowski"};
        String[] casts =  {"Keanu Reeves", "Laurence Fishburne","Carrie-Anne Moss", "Hugo Weaving"};
        Movie movie = new Movie("The Matrix",  directors,  casts,1999);
        movie.showInfo();
        System.out.println("searchTitle(\"matrix\") : " + movie.searchTitle("matrix"));
        System.out.println("searchTitle(\"hello\") : " + movie.searchTitle("hello"));
        System.out.println("searchDirectors(\"Andy\") : " + movie.searchDirectors("Andy"));
        System.out.println("searchDirectors(\"Charles\") : " + movie.searchDirectors("Charles"));
        System.out.println("searchDirectors(\"chowsk\") : " + movie.searchDirectors("chowsk"));
        System.out.println("searchCasts(\"Charles\") : " + movie.searchCasts("Charles"));
        System.out.println("searchCasts(\"Hugo Weaving\") :  " + movie.searchCasts("Hugo Weaving"));
        System.out.println("searchCasts(\"reeves\") : " + movie.searchCasts("reeves"));
        System.out.println("search(\"MATRIX\") : " + movie.search("MATRIX"));
        System.out.println("serach(\"HELLO\") : " + movie.search("HELLO"));
    }
}

Output

Title: The Matrix
Directors: Andy Wachowski, Larry Wachowski
Casts: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving
Year: 1999
searchTitle("matrix") : true
searchTitle("hello") : false
searchDirectors("Andy") : true
searchDirectors("Charles") : false
searchDirectors("chowsk") : true
searchCasts("Charles") : false
searchCasts("Hugo Weaving") :  true
searchCasts("reeves") : true
search("MATRIX") : true
serach("HELLO") : false

MovieDatabase.java

The class represents a database of movies. You can assume that there are no more than 1000 movies in the database. You can have as many private members as you like.
The class has the following public methods:
Constructor

MovieDatabase(): construct an empty database.

Methods

void add(Movie movie): add a movie to the database, ignore it if there are more than 1000 movies.
void search(String keyword): search the keyword in all the movies in the database. If a movie contains the keyword, prints out the information at the Dos Prompt. See the sample output for the format.
void showAll() : prints out all the movies at the Dos prompt. See the sample output for the format.

Test3.java

public class Test3 {
    public static void main(String[] args) {
               String[] directors = {"Andy Wachowski", "Larry Wachowski"};
               String[] casts =  {"Keanu Reeves", "Laurence Fishburne","Carrie-Anne Moss", "Hugo Weaving"};
               Movie movie1 = new Movie("The Matrix",  directors,  casts,1999);
               Movie movie2 = new Movie("The Matrix Reloaded", directors, casts, 2003);
               String[] directors3 = {"Quentin Tarantino"};
               String[] casts3 = {"Uma Thurman", "David Carradine", "Lucy Liu"};
               Movie movie3 = new Movie("Kill Bill: Vol. 1", directors3, casts3, 2003);
               String[] directors4={"John Woo"};
               String[] casts4 = {"Ben Affleck", "Uma Thurman"};
               Movie movie4 = new Movie("Paycheck", directors4, casts4, 2003);
               MovieDatabase database = new MovieDatabase();
               database.add(movie1);
               database.add(movie2);
               database.add(movie3);
               database.add(movie4);
               database.showAll();
               System.out.println("Search for Thurman................. ");
               database.search("Thurman");
               System.out.println("Search for Matrix.................... ");
               database.search("Matrix");
    }

Hints

In String class, toLowerCase(), toUpperCase() return lower case (or upper case) or the String. Please refer to this link and this link.
In String class, indexOf(String str) returns the index within this string of the first occurrence of the specified substring, it returns -1 if str is not found. You should use the method in all the search methods. Please refer to this link.
