Sneaker App

This is a Java console application that allows users to view upcoming sneaker releases, add sneakers to a shopping cart, and checkout. Before accessing the app, the user must authenticate with a default username and password.

How to Run

To run the program, you will need to have Java installed on your machine. Once you have Java installed, follow these steps:

1. Clone this repository or download the source code as a zip file.
2. Open the project in your preferred Java IDE (such as Eclipse or IntelliJ IDEA).
3. Compile and run the SneakerApp class.

Alternatively, you can run the program from the command line by navigating to the root directory of the project and running the following commands:

javac oopsdan/SneakerApp.java
java oopsdan.SneakerApp

Authentication

The default username and password are both "Admin". The application uses SHA-256 hashing to secure the password.

Usage

The application will display a main menu with the following options:

1. View Upcoming Releases
2. View Shopping Cart
3. Add Sneaker to Shopping Cart
4. Remove Sneaker from Shopping Cart
5. Checkout
6. Exit

To make a selection, enter the number corresponding to the option and press Enter.

View Upcoming Releases

This option displays a list of upcoming sneaker releases. The release dates are hardcoded in the Sneaker objects in the SneakerApp class.

View Shopping Cart

This option displays the items currently in the shopping cart, if any.

Add Sneaker to Shopping Cart

This option displays a list of available sneakers and prompts the user to select a sneaker to add to the shopping cart.

Remove Sneaker from Shopping Cart

This option displays the items currently in the shopping cart and prompts the user to select a sneaker to remove from the shopping cart.

Checkout

This option displays the total price of the items in the shopping cart and prompts the user to confirm the purchase.

Exit

This option exits the application.

About the Code

The LoginSystem class handles user authentication by comparing the entered username and password to the default values. The Sneaker class defines the properties of a sneaker, and the SneakerApp class contains the main logic of the application.

The application uses an array to store the available sneakers and an ArrayList to store the items in the shopping cart.

The application uses Java's built-in LocalDateTime class to handle date and time calculations.
