All the answers I’m getting are actually confirming my theory.

For vanilla code I get it. Vanilla Java I can totally understand where things came from and why. It’s the libraries that get me. How am I supposed to know that the library expects X? Is a very common question I have.

I understand it at the end but that’s because someone’s given me the answer. But I couldn’t derive that by deduction if I wanted to because I didn’t even know that was a thing.

And all the guys giving the tutorials seem to be running off their memory but they don’t tell you how they figured it out
