Movie Store – Part 5

In this workbook, you will add interactivity to the application.

Task 1

---

Inside Main, make the Store object a class variable.

Task 2

---

Inside Main, define a function named loadMovies.

/**
 * Name: loadMovies <--------
 * @param fileName (String)
 * @throws FileNotFoundException
 *
 * Inside the function:
 *   - 1. loads movies from <fileName>.txt.
 *   - 2. adds all movies to the store object's movie field.
 *        Hint: You will need to 'split' a String into three.
 */

The function receives the fileName from which you will load movies.

/**
 * Name: loadMovies
 * @param fileName (String) <-------
 * @throws FileNotFoundException 
 *
 * Inside the function:
 *   - 1. loads movies from <fileName>.txt.
 *   - 2. adds all movies to the store object's movie field.
 *        Hint: You will need to 'split' a String into three.
 */

The function throws a FileNotFoundException.

/**
 * Name: loadMovies
 * @param fileName (String)
 * @throws FileNotFoundException <--------
 *
 * Inside the function:
 *   - 1. loads movies from <fileName>.txt.
 *   - 2. adds all movies to the store object's movie field.
 *        Hint: You will need to 'split' a String into three.
 */

Follow the steps to complete the function. Note, you can't use scan.next() because it picks up the next String separated by white space. In this case, the separator is two hyphens --.

You'll need to:

• Pick up the entire line as one String (nextLine).

• Research how to 'split' a String into mutiple Strings.

• Research how to parse a Double from a String (for the rating).

/**
 * Name: loadMovies
 * @param fileName (String)
 * @throws FileNotFoundException
 *
 * Inside the function: <------------
 *   - 1. loads movies from <fileName>.txt.
 *   - 2. adds all movies to the store object's movie field.
 *        Hint: You will need to 'split' a String into three Strings.
 */

From main(), try to call loadMovies. Then, print:

• "MOVIES LOADED\n\n"
• the movie object.

In case of a failure, catch the FileNotFoundException.

Expected Output:

Task 3 -- manageMovies

---

Inside Main, add a method called manageMovies.

/**
 * Name: manageMovies <--------
 * Inside the function:
 *   - 1. Starts a new instance of Scanner;
 *   - 2. In an infinite loop, the user can choose to a) purchase or b) rent c) return.
 *   -        case a: ask for the name and sell them the movie.
 *   -        case b: ask for the name and rent them the movie.
 *   -        case c: ask for the name and return the movie.
 *   - 3. call close() from the Scanner object.
 */

Create a Scanner object.

/**
 * Name: manageMovies
 * Inside the function:
 *   - 1. Starts a new instance of Scanner; <-------
 *   - 2. In an infinite loop, the user can choose to a) purchase or b) rent c) return.
 *   -        case a: ask for the name and sell them the movie.
 *   -        case b: ask for the name and rent them the movie.
 *   -        case c: ask for the name and return the movie.
 *   - 3. call close() from the Scanner object.
 */

• Make a while loop that runs infinitely.

• println: \nWould you like to \n\ta) purchase\n\tb) rent \n\tc) return.

/**
 * Name: manageMovies
 * Inside the function:
 *   - 1. Starts a new instance of Scanner;
 *   - 2. In an infinite loop, the user can choose to a) purchase or b) rent c) return. <----------
 *   -        case a: ask for the name and sell them the movie.
 *   -        case b: ask for the name and rent them the movie.
 *   -        case c: ask for the name and return the movie.
 *   - 3. call close() from the Scanner object.
 */

After performing one of the actions, println "\n\nUPDATED MOVIES\n\n"followed by the updated list of movies. Finally, call manageContacts from from inside the try block.

Task 4: The finally block

---

finally gets called after the try - catch block.

Add a finally block at the end of the try - catch block

finally {

   //gets called last (after try - catch)

}

This is a good place for cleanup code. In this case, feel free to print: "Process Complete".
