    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)

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 🤣.
