We wanted to encourage students to improve their java coding skills.

What it does

The user has to sign up on the web application (after creating the account it can simply log in). The user can choose a task, write a solution and then upload it on the site. It will be automatically checked.

How we built it

We split in two teams (front-end and back-end) and we have been simultaneously working on each part . Before starting we made a short design of how the final project should look like. We have 6 HTML and PHP pages (log in, sign up, error, list of problems, each problem and home). For the sign up and log in, we are using a MySQL database. We hosted it on the Google Cloud Platform in a virtual machine running Debian. The code input by the user is tested in a sort of "sandbox" - to prevent malicious code from being run on the server.

Challenges we ran into

We had some difficulties when implementing Ace. Also we could not properly display the mistakes of the user's solution.

Accomplishments that we're proud of

We are proud we were such an efficient team. We managed to learn many new things in a really short time. It was an amazing experience!

What we learned

It was the first time we worked in such a complex project. We learned how to use html, php and mysql tools more efficiently. Even more, we extended our knowledge regarding java script, java and git environment.

What's next for Java Tester

We would like to implement a "Contest" section so that you can invite friends in a competition. In the future we want to work more on the error output.
