Black Friday 2025

Again, we bring you our most popular classes, with up to $500 off. This year, we also have a 10% discount for our upcoming "Extreme Java Concurrency Performance" and "Mastering Virtual Threads" bundle. This is taught live from 10:00-16:30 Berlin Time, December 8-12. It's an excellent course and when we did it two weeks ago, we found a concurrency bug in the JDK. In addition, we have a new course on modernizing to Java 25 - really fun with lots of code to refactor. Or turn on your favourite AI and watch it do it for you.

1. Practical Refactoring to Modern Java: 32% off
2. Java Specialists Superpack 2025: $500 off (Includes free upgrade to Superpack 2026 when it is released)
3. Java Concurrency Aficionados 2024: 42% off
4. Extreme Java Concurrency Camp Live Class December 8-12: 10% off
5. Mastering Virtual Threads in Java (Loom): 38% off (Includes free upgrade to Java 25 version when it comes out in early 2026)

Our Black Friday and Cyber Monday specials start on Friday the 28th November, and continue to the end of the 4th of December, in order to give you lots of time to get budget approval from your company. We can also do the payment directly via invoicing and bank transfer.

Enjoy and happy Black Friday!

Kind regards from Crete
