I've gotta say John, I am doing Java in Uni, and I have their book, and a few others, but your videos wipe the floor with them when it comes to clarity and explanations.
Seriously, if you aren't a teacher, you should be one.
I was disheartened when I was reading the course materials for my class, but just watching your videos has really helped with everything.
Thank you very much indeed.

Your channel single handedly allowed me to pass my intro to java course. Went from failing to a 3.0.
Thank you!

You make things look so much easier. I feel like I have watched perhaps an entire lecture after most (if not all) of your videos.
And I mean that in the best possible way. Keep being great, you certainly have a gift in teaching!

this keyword was so confusing to me as a beginner- more than most other concepts!!-video really nails it down, and helps reinforce my understanding

[JusQuelle]

This was a great explanation of the "this" keyword, thank you so much!

[bhaweshpandey]

I am a beginner, so I guess it will take sometime to thoroughly grasp all at once.
Thanks for the explanation man!!

Thank you John! I’m a sophomore Software Engineer, and you explain things much clearer than my professor ✨

I am just learning Java (from mechanical engineering, career switch) and your videos are great.
Keep it up and Thank you !

[wallywild]

Plz keep doing this in just a couple months you’ve provided so much value

You explain it better than anyone, bc you inform us what we need to know NOT what you know.

I think that using "this" in class methods, like constructor or getters and setters, is not for avoid confusing between the function parameter and the filed name.
The uses of "this" is for referencing the specific object in memory beacause we can have many other objects of the same class.

I've watched a bunch of your videos today just in two hours and I'm amazed of how you make things look so clear in just seven minutes or so per topic :D Great job!

[sportingdirector]

Thank you! I'm so appreciative of this that I'll watch the ad in its entirety so you can get some of the money!

[gigachard]

Omg been fighting with Intellij to understand getters, setters and constructors and watching This was an instant 4 piece! Thank you!!!

Dang near perfect, and no, I don't have any complaint at all, except that in other languages some good developers felt that "this" was redundant in instance methods and should generally be avoided as noise (their approach was non-ideal when the natural name for a method parameter was the same as a data member, of course -- they would wind up having to munge those). On the theme of "I love how you do brief intros that don't overwhelm the learner with minor details without lying or teaching anything they will have to learn later" a very good book I am reading does just that. In a quest to prepare the reader for cert exams, they don't merely ignore stuff that isn't on the exam in that area, but actively make some misstatements that won't affect one's performance on the exam, but if you go beyond later, you will actively have to unlearn some "convenient lies" that they could have just ignored instead. It is a fine line, but you normally always land on the right side of it. There are extremely few "untrue statements" or "non-facts" found in your videos in service of making a good introduction. That is not easy to pull off, and I really appreciate it.

The explanation is insanely clear! Saved me from another course tbh
