Movie Store – Part 3

In this workbook, you will apply the Big 3 steps to the Store class.

The store is identified by the movies that it manages. It can add movies, sell them, and allow the user to rent/return them.

Task 1 – Adding the field

---

Add the movies field to the Store class. The number of movies can increase or decrease so use an ArrayList.

Task 2 – The Big 3

---

1. Constructor.

   • It receives no parameters.

   • It sets the field equal to a new object of the ArrayList class.

2. Getter: getMovie

   • It receives one parameter: int index.

   • It returns an object at the requested index.

3. Setter: setMovie

   • It receives two parameters: int index, Movie movie.

   • It sets an element equal to a copy of the object being passed in.

As you're applying each step, careful not to fall into the reference trap.

Task 3 – addMovie.

---

• This method is void

• Receives one parameter: Movie movie.

• Adds a movie to the ArrayList.

Task 4 – sellMovie.

---

• This method is void.

• Receives one parameter: String movieName.

• Removes the movie that matches the name passed in.

Task 5 – rentMovie.

---

• This method is void.

• Receives one parameter: String movieName.

• Sets isAvailable equal to false.

Task 6 – returnMovie.

---

• This method is void.

• Receives one parameter: String movieName.

• Sets isAvailable equal to true.

Task 7 – Remove sellMovie, rentMovie and returnMovie

---

You probably noticed that rentMovie, sellMovie and returnMovie have identical code. Instead of three methods, create one:

• named action.

• accepts two parameters: String name, String action.

• runs three cases: sell, rent, and return.

Task 8 – toString.

---

• Set a String variable temp that equals "".

• Loop through every movie in the movies field.

• During each run, add the toString of each movie.

• During each run, add two new lines \n\n to temp.

• return temp;

Task 9 – Testing the code

---

• Inside main(), create an object of the Store class.

• add three movies to the movies field. Use the following values:

  • The Shawshank Redemption--Blue-Ray--9.2

  • The Godfather--Blue-Ray--9.1

  • The Godfather: Part II--DVD--9.0

• Print the Store.

Expected Output:

• call action and sell "The Godfather".

Expected Output:

• call action and rent "The Shawshank Redemption"

Expected Output:

• call action and return the movie "The Shawshank Redemption"

Expected Output:

Good Luck!
