- The course progression (from JVM internals to more high-level topics) - Some insights from practical exercises - Visual style (not some presentation, but a nicely styled page)
Ivan Suvorov - Deutsche Bank
Course - Java Advanced
the knowledge of the trainer was very high - he knew what he was talking about, and knew the answers to our questions
Adam - Fireup.PRO
Course - Advanced Java Security
That we got a complex overview also about the context - for example why do we need some annotations and what they mean. I liked the practical part of the training - having to manually run the commands and call the rest api's
