I got back into Java recently after not using it for like 8 years and have been haphazardly using == for strings and it has been working, presumably because I have been always using strings as state variables in games, and so have been manually typing the strings in my conditions as literals (if (facing == "up")) etc. I saw a comment on another video and I'm glad I found this early enough to refactor everything. haha.

You are great. Congrats for channel and being Team Leader. Maybe you could/should make a video talking about what should a junior know. I think i know equals now, exceptions/throw/finally/catch etc, im learning generics and i undertand but i saw a generic method in an interview(company was about HR, and i was asked 4 Design Patterns which i knew but wasnt good enough for company anyway) i had no idea what it was even if i knew generics it was kind of pro code/ultra weird and hard i think it was with lists btw..i also hate leetcode i prefer videos like yours to actually learn java. I would also learn more from you cause you good and you enjoyable i hope you do the same in your job irl. i think i also know most of collections hashmap/set etc

The underline is even if the primitive or non primitive or user defined type java will check for the memory location and not the values.. (if the values are same then uses same memory location).

John, where did you get the source and how did you attach the source to the binaries? UPDATE: solution is to point your JRE path to the path with the JDK instead!
