I’ve really learnt some useful things during each half-day session; I’ve gained a deeper understanding of how Java works.

A rewarding course, despite my ‘beginner’ level in Java. I wasn’t always able to keep up with all the technical aspects, but it did allow me to discover many concepts and gain a better understanding of the Java ecosystem. This course gave me a good overview and some ideas on how to deepen my knowledge. Thank you
