I like the lectures, but they are not explained well enough for someone who is new to Java. I wouldn't recommend it because some things are skipped over or not explained properly, which is confusing and means you have to check the whole project because of a tiny point, which takes a lot of time. On the other hand, the tutors try to finish the videos really quickly, and I think he thinks that if he records the videos quickly, it will be easier, but it's not really. For anyone who wants to buy this course, I would recommend thinking twice and not being fooled by what he said. I worked as a Java developer and I know what you need; I'm not theoretical. Don't be fooled by that sentence.

Instructor Bio
Hi!
My name’s Adrian and I’m an engineering manager and a former senior software developer. I specialise in back-end languages such as Java and Python. My programmer portfolio also includes lots of database technologies: both SQL and NoSQL databases. I hold a Master’s Degree in Computer Science.
I have over 10 years of experience teaching people IT online. What makes my courses special is their practical background – I’m an active developer, not an IT theorist, so I know the best practices. I also know what programming skills are in demand.
My courses are:
- based on practice so that you don’t learn useless theory,
- straight to the point to save your time,
- easily digestible because I want you to understand it all without problems.
