Competitions
Compete with Professionals from Other Countries
Why to Compete?
XtremeJ had, in total, four different competitions: XtremeJ Competitive Programming, XtremeJ Challenge, XtremeJ Breakout Room, and XtremeJ Hackathon. There are many advantages in taking part. We believe that the following are the more important ones.
Becoming Active and Having Fun
Listening to talks delivered by others might be interesting and enjoyable. Yet, usually when being passive in listening to others, at some point, it might become tedious. The need to be more active always exists. The competitions we have in XtremeJ, and especially the ones taking place using the Kahoot platform, allow all participants to take part and show off their professionalism.
Showing Off Your Expertise on LinkedIn
We honor the winners with a nice banner that shows off their success, and share it on social networks, such as LinkedIn. Showing off your professionalism on LinkedIn brings respect.
Yielding new Career Opportunities
If you are between jobs, or a graduate looking for the first junior position, or are thinking about leaving your current job, our competitions might yield new career opportunities. We honor the winners and spread the word about the winners on LinkedIn. That might lead to new career opportunities.
XtremeJ Competitive Programming
XtremeJ Competitive Programming is a dynamic Kahoot-based competition that brings the spirit of classic competitive programming to life. Participants will face algorithmic and problem-solving challenges commonly seen in major contests, designed to test their coding expertise, logical thinking, and ability to perform under pressure. This interactive format ensures not only a tough intellectual workout but also an engaging, game-like experience where speed, accuracy, and knowledge all matter.
We were very excited to announce Tomer Armarnik as the winner of the XtremeJ Competitive Programming Challenge. Tomer demonstrated outstanding problem-solving skills, deep technical expertise, and exceptional performance under pressure, standing out among a strong field of participants. His achievement reflects both mastery of Java fundamentals and the ability to apply them effectively in complex, time-constrained scenarios. Congratulations to Tomer on this well-deserved accomplishment.
XtremeJ Challenge
XtremeJ Challenge is the flagship knowledge competition for every Java developer who loves a real challenge. This exciting contest dives deep into all aspects of the Java programming language, from exploring the latest features introduced in recent versions to revisiting core fundamentals that every developer should know and even uncovering the fascinating history that shaped Java into the global standard it is today. Each question is carefully designed to test not only technical accuracy but also depth of understanding, ensuring that participants demonstrate both skill and insight. More than just a quiz, this is a battle of expertise, speed, and confidence. Whether you are a seasoned professional or a passionate learner, the XtremeJ Challenge gives you the stage to prove your mastery, connect with fellow developers, and claim your spot as a true Java professional.

This achievement reflected both technical sharpness and a strong aptitude for collaborative, challenge-driven problem solving. Congratulations to Ronen on this impressive accomplishment.
XtremeJ Hackathon
XtremeJ Hackathon is the ultimate test of speed, creativity, and coding mastery. Participants face a real-world programming challenge and race to be the first to deliver a complete working solution. You can use any tool, any library, and even AI—the battlefield is wide open. What matters is solving the problem fast, submitting the code along with the correct output, and outpacing everyone else. This is not just about knowledge; it’s about thinking on your feet, leveraging every resource at your disposal, and proving you can build under pressure. The one who solves it first earns glory, recognition, and the crown of XtremeJ Hackathon winner..
