~~~ Here are a Few Reviews on The in28Minutes Way ~~~
Excellent, fabulous. The way he has prepared the material and the way he teaches is really awesome. What an effort .. Thanks a million
A lot of preparation work has taken place from the teacher and this is visible throughout the course.
This guy is fantastic. Really. Wonderful teaching skills, and goes well out of his way to make sure that everything he is doing is fully understood. This is the kind of tutorial that gets me excited to work with a framework that I may otherwise not be.
The best part of it is the hands-on approach which the author maintained throughout the course as he had promised at the beginning of the lecture. He explains the concepts really well and also makes sure that there is n

I enjoyed this course. I learned a lot from this teacher. This looks like this course took a lot of time and effort, and I enjoyed the exercises, puzzles, and lessons. This is a great course.

Course flow is logical. Even some of the more complicated core java topics are explained very well.

sorry for my first review, i realy like your course

The course was fantastic. Now I am able to create basic programs and understand complex programs easily. The way of teaching was great.

It is a great course. Only it is a pitty that teacher does not follow programming conventions.

The coursed helped me pass a test about java and object-oriented programming concepts. It is a great introduction to Java and also can be used as a reference guide to the language.

This course is the best informative java course and very practical. I recommend the course to any person thinking of starting the journey to Java

This is a very good course for learning Java basics. Anyway, programming is best learned with practice: perhaps having a few "complex" exercises at the end of every section, in which one can test what they have learned, would make this course perfect.

I am a computer science student brushing up on the fundamentals of java syntax before I take my Data Structures course. This was an awesome guide and properly detailed covering topics that can get you up and running in less than a month if you are dedicated to learning these modules once a day like I did!

Excellent narration of various topics.. Very good examples to put across the message.

The instructor is very knowledgeable and takes the time to go into each topic in great detail!While some instructors just browse through topics leaving you confused, this instructor explains everything! I would highly recommend this course!I am hoping that this instructor releases more courses in the future! Perhaps NoSQL, asynchronous event based messaging (Vert.x, reactor core), or spring Roo topics?

The course was really informative with various puzzles and exercises to help understand the concept better.
