Java Bootcamp – Workbooks and Challenges

Movie Store – Part 1

From Java Bootcamp Resources -> Module 2 -> 8. Exception Handling -> Exception Handling Workbooks, open the folder: movie-store.

The requirements.

Based on the requirements, there are two types of objects:

We can describe each movie using six fields: name, format, rating, sellingPrice, rentalPrice, and isAvailable.

The store is identified by the movies that it manages. First, it adds movies to its collection. It also sells movies and allows the user to rent/return them.

The tasks in this workbook apply to the Movie class.

Task 1 – Fields

Add the necessary fields to the Movie class. Protect each field using the private keyword.

Task 2 – The Big 3

If a class has fields, you need to apply the Big 3:

  • Constructor

  • Getters

  • Setters

Task 2.1 – Constructor

  • The constructor will only receive three parameters: name, format and rating.

  • At first, isAvailable is equal to a fixed value of true.

  • Use conditional assignment syntax (? and :) to update the selling and rental price (see requirements).

Task 2.2 – Getters and Setters

You can autocomplete the getters and setters using Visual Studio Code Intellisense.

  • Note: getters for the boolean type are written as isFieldName. Here are some examples:

    • boolean empty -- getter: isEmpty

    • boolean available -- getter: isAvailable

    • boolean ready -- getter: isReady

    • boolean isReady -- getter: isReady

  • This note was added to your next cheat sheet.

Task 2.3 – setSellingPrice

Make setSellingPrice private. The caller should not be allowed to access it. The format should determine the sellingPrice.

Task 2.4 – setRentalPrice

Make setRentalPrice private. The caller should not be allowed to access it. The format should determine the rentalPrice.

Task 3 – Copy Constructor

To avoid the reference trap, we need a way to copy Movie objects. So, add a copy constructor.

Task 4 – toString

Every class that models an object should have a toString method.

Add a toString method to your class, and return a String that adheres to this format:

return "\t Name: " + <name> + "\n" +

"\t Format: " + <Format> + "\n" +

"\t Rating: " + <Rating> + "\n" +

"\t Selling Price: " + <Price> + "\n" +

"\t Rental Price: " + <Price> + "\n" +

"\t Availability: " + <in-stock if true and rented if false> + "\n";

Task 5 – Test your code.

  • Inside main(), create a new object of the Movie class and print it.
