Your videos are very helpful. After taking an 8 week course, this 15 minute video just explains it all so well. Great review and even helps me both recall and retain the concepts so much better than just the course by itself. I wish I had watched this when first learning Java and feeling like it true was a foriegn language I could never pick up.

I'm a beginner programmer and I've been learning python actually for about 3 weeks now, but I am interested in learning about Java too. Gotta say compared to a simple print("Hello World") in python, the way to print hello world in java seemed way more complicated. this video helped me to have a better understanding of how python scripts work.

This is simply amazing. I don't know if it's just the fact that it's been about 8 years since I started my programming journey, but I don't recall any other moment where Java actually made sense to me. Just realized that I already knew pretty much everything that was talked here, just not in the right order

To be honest, in my 3 years of experience, I hadn't come across a very straightforward and understandable explanation of Static vs Non-Static. Whenever people try to explain it, they tend to prioritize either time or quality, sacrificing one over the other. But in this case, you managed to provide a nice explanation without compromising on either time or quality. Great job! ( I was really struggling to explain this to a friend)

This was so helpful! I’m in week 3 of class and feel like I haven’t even started yet. I literally just signed up for a tutor, but wanted to find YT video to help in the meantime. You definitely made some of it make sense…like I get the feel of what is actually going on now. Versus looking at a bunch of codes just doing what I can to follow along. I was like why I am even writing this, why does it have to go here, what is one line doing for the other, etc.. I was feeling like I needed an “Intro to Introduction to Java” class 🤣.
