♣️ ♥️ The BlackJack Game ♠️ ♦️

1. What is it

A pretty basic implementation of the famous game BlackJack, written in JAVA using native Swing components, SQLite as the internal database, MigLayout as the layout manager and Flatlaf as a third-party look-and-feel provider.

2. How to use?

You can either clone this repository and setup a workspace in your IDE or simply download the latest jar file in our releases folder. To create a new player and start playing, just type an username and a checkbox will appear as soon as you start setting your password. Then tick the checkbox to create it and click Login.

If the checkbox does not come out, it means the username you picked already exists in the database, so pick another one.

3. Docker Usage 🐳

If you are a JAVA GUI application & Docker master, feel free to try to help me fix the problem below which is preventing us from having a pretty cool and functioning Docker image of the game.

Download the image 💿

Once you have Docker CE installed an running, from your Linux terminal or Windows cmd, type:

$> docker pull jrkrauss/blackjack:latest

Create the container and run/ship it 🚢

$> docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY jrkrauss/blackjack:latest

P.S: This is the problem I mentioned before. The container execution exits with the error below:

	No protocol specified
