Java Challenge Belgium 2017
Java Challenge Belgium 2017

Do you think that you have what it takes to become Belgium’s Java champion? From March to April 2017, the company Groupe Open organizes its first Java challenge in Belgium


The first round takes place online. Our finalists will then compete for the title of the "Java Champion 2017" at the end of April. 

How to participate?

The registration is open for the entire duration of the challenge. You only need to register on EDITx.

How is the challenge organized?

You will have 15 minutes to give the correct answer to as many questions as you can. The Challenge consists of a set of multiple-choice questions with one or multiple correct answers.

The challenge allows two Jokers: the "50/50", in which the computer eliminates half of the answers and "Ask the Challengers", in which the percentage of the challengers who chose each specific answer is displayed to you.

After having completed the Java Challenge, you will see your result immediately, but you won't see the answers. We will email the details of the scores to all players once the Challenge will be closed so that the correct answers can't be shared among the players during the running time of the Challenge.

12 finalists will be identified at the end of the first round. If you qualify or if you rank among the 25 best participants, your name, first name and your score will be posted on the leaderboard and announced to all the challengers via the Challenge Results email. There will be two leaderboards: a global leaderboard ranking all the participants and a leaderboard dedicated to the students. The name and first name of the best 20 students will be publicly accessible at the end of the Challenge.
