JDBC LAB:

Define a movie database application that allows a user to look up information about a movie and provide a review for a movie. Your application should provide the following features:

? List all movies that are rated a particular rating (PG, PG-13, R, etc) entered by the user.

? All a user to post a review for a particular movie. A review consists of review text and a star rating with o5 stars = Excellent o 4 stars = Good o 3 stars = Neutral o 2 stars = Poor o 1 star = Very Poor

? List all reviews for a movie and include the average star rating for the movie Your solution should read the database connection information (jdbc driver and connection url) from a properties file called database.properties.

You can create a console based application to implement this application or write a GUI interface to provide these movie database features described above. The only requirement is that the class containing the main method should be called MovieDBApp. Here is some information about the database table schema you will be using:

A set of commands to create and populate the MOVIE and MOVIE_REVIEW tables are provided below.

CONNECT 'jdbc:derby:C:\temp\CSC251\Lab11DB;create=true';

CREATE TABLE MOVIE (MOVIE_ID int not null primary key GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),MOVIE_NAME varchar(100), RATED varchar(10));

CREATE TABLE MOVIE_REVIEW (REVIEW_ID int not null primary key GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1), MOVIE_ID int, REVIEW varchar(500), STARS int);

INSERT INTO MOVIE(MOVIE_NAME, RATED) values('Divergent', 'PG-13');

INSERT INTO MOVIE(MOVIE_NAME, RATED) values('Muppets Most Wanted', 'PG');

INSERT INTO MOVIE(MOVIE_NAME, RATED) values('The LEGO Movie', 'PG');

INSERT INTO MOVIE(MOVIE_NAME, RATED) values('Saving Mr. Banks', 'PG-13');

INSERT INTO MOVIE(MOVIE_NAME, RATED) values('Her', 'R');

Notice that in the CONNECT statement has a portion of the connection URL highlighted. This statement assumes that you will want to have the database files located in C:\temp\CSC251\Labb11DB. If you would like the database files to be located somewhere else on your system, you will need to update this statement. Also, when the MOVIE and MOVIE_REVIEW tables are created the MOVIE_ID and REVIEW_ID are set to be automatically generated by the database. As a result, any SQL statements to INSERT INTO the MOVIE or MOVIE_REVIEW table will not need to specify and ID. Instead, the database will automatically generate these values for you.

import java.util.Scanner;

public class MovieDBApp { private static final int SELECTION_FIND_MOVIE = 1; private static final int SELECTION_WRITE_REVIEW = 2; private static final int SELECTION_VIEW_REVIEWS = 3; private static final int SELECTION_EXIT = 4;

public static void main(String[] args) { Scanner in = new Scanner(System.in); int selection = getMenuSelection(in); while(selection != SELECTION_EXIT) { if(selection == SELECTION_FIND_MOVIE) { System.out.print("ENTER RATING>> "); String rating = in.nextLine(); } else if(selection == SELECTION_WRITE_REVIEW) { System.out.print("ENTER MOVIE NAME>> "); String movieName = in.nextLine(); System.out.print("ENTER NUMBER OF STARS (1 - 5)>> "); int stars = in.nextInt(); in.nextLine(); System.out.print("ENTER MOVIE REVIEW TEXT>> "); String reviewText = in.nextLine(); } else if(selection == SELECTION_VIEW_REVIEWS) { System.out.print("ENTER MOVIE NAME>> "); String movieName = in.nextLine(); } else { System.out.println("INVALID MENU OPTION"); } selection = getMenuSelection(in); } in.close(); } public static int getMenuSelection(Scanner in) { int selection = 0; System.out.println(" --- MAIN MENU ---"); System.out.println("(1) Find Movie"); System.out.println("(2) Write Review"); System.out.println("(3) View Movie Reviews"); System.out.println("(4) Exit"); System.out.print(" ENTER MENU SELECTION>> ");

if(in.hasNextInt()) { selection = in.nextInt(); in.nextLine(); } else { in.nextLine(); } System.out.println();

return selection; }
